The stations that did not pass the discordant and heterogeneity test were discarded from the regional frequency analysis. Include a date for which you would like to see weather history. Consequently, the aim of this study is to select a broad category of climatic, geographical, and statistical attributes of the maximum 24-h rainfall of the Urmia Lake Basin for 63 selected stations for the period 1979–2008 and next to determine an appropriate weight for each of the attributes in each defined category. ous regions of Kerala under each cluster are identified. The regions are geographically well distributed over the area The actual rainfall received in Kerala during the southwest monsoon season (June 1 to September 30, 2020) was 2246.0 mm as against the normal rainfall of 2038.7 mm which was normal with a departure of 10.2 per cent from the normal. Government engineering college thrissur Kerala india, http://creativecommons.org/licenses/by-nc-nd/4.0/, -review under responsibility of the organizing committee of ICETEST – 2015, Engineering, Science and Technology (ICETEST, s in a given cluster tend to be similar to each other and object. Access scientific knowledge from anywhere. All the districts of Kerala received deficient rainfall during the period. Kannur district topped the charts with 2537.4 mm. Three major periods were identified. Initially RMSSTD value d, Homogeneous regions of Kerala under each cluster are identified by ‘Thiessen Polygon Method’ an, Average annual rainfall of each cluster is calculated and tabulated in Table 3 and plotted in Fig. The F-test is used to evaluate the homogeneity of each sub-region. Dealing with individual rainfall station is time consuming as well as prone to more variation. Knowledge about precipitation is indispensable for hydrological and climatic studies because precipitation subsidizes projects related to water supply, sanitation, drainage, flood and erosion control, reservoirs, agricultural production, hydroelectric facilities, and waterway transportation and other projects. Later, considering the heterogeneity in the hydroclimatic and topographic details, entire rain gauge stations have been clustered into six hydroclimatically homogeneous regions; namely, northeast (NE), northwest (NW), southeast (SE), southwest (SW), coastal, and central regions, by using the k-mean clustering technique. They are dow, SWAT. Karnataka receives about 80% of the annual rainfall during the South-West monsoon period (June to September), 12% during the post-monsoon period (October to December), 7% during the summer season (March to May) and only 1% rainfall is received during the winter season (January to February). Seven districts got more than 2000mm, six districts got between 1100 mm and 1800 mm while Thiruvananthapuram got the least amount of rain at 719.7 mm. This study aimed to provide a historical mega drought information of Korea using the long-term precipitation for longer than 300 years that were observed by the Korean Meteorological Administration (KMA) during 1908–2015, and paleo-climate data by the Korea’s ancient rain gauge (Chuk-Woo-Kee) during 1777–1907 and future climate change scenario from 2017 to 2099. and compared: the rotated principal component analysis (RPCA) in conjunction with Ward's method, and the RPCA in conjunction The two regional distributions obtained not only correspond fairly well to the large, well-known physical regions of Switzerland, but also go much further, separating the Swiss Plateau into 3 clearly differentiated regions, for example. In the present context of climate change and increasing demand for water, it is crucial to identify the origin, groundwater flow dynamics and mean residence times for sustainable management of water resources. Kerala The state with 14 districts had 2310.2 mm rain, 13% above normal. Meteorology and atmospheric dynamics (climatology; precipitation; general or miscellaneous). April–May–June (AMJ), July–August–September (JAS), and October–November–December (OND). El análisis de tendencias de la concentración de lluvia mensual no muestra cambios significativos en el periodo de estudio. Like Ward's method, the values of F-ratio for the k-means algorithm also confirm the homogeneity of all seasons/sub-regions. This transgression, also recognized in Sfax coast, revealed by the dominance of lagoonal ostracod associated to coastal and marine taxa, allows the settlement of an open lagoon. Kannur received just 1852.5mm and only nine districts received more than 1000 mm of rain. regional rainfall patterns. in each cluster is determined by using dendrogram. Rainfall 2016-17 monsoon Rainfall (June – september) 1.7. RMSSTD is represented mathematically as given in “(1)”. To investigate the weighting effect in regionalizing and to determine the appropriate weight for each defined attribute, respectively, Ward's clustering technique, principal component analysis, and correlation coefficients matrix methods were used. Most months of the year are marked by significant rainfall. season/sub-region is also provided and compared. an approach that, The lack of data in rainfall stations of Iran is one of the main problems in design and management of hydrologic systems. Annual and seasonal precipitations from 1977 to 2012 recorded in 30 stations are used in this study. “This means rainfall happens for a short duration but the amount of precipitation will be higher,” he said. Optimal numbers of clusters in the four precipitation series are determined using the Gap statistic for K-means clustering and using the extended Gap statistic for Fuzzy C-means clustering, and are found as 3, 1, 3 and 2 for annual, pre-monsoon, monsoon and post-monsoon, respectively. Monthly data from 34 climate stations for rainfall from 1991 to 2013 are used in the cluster analysis. Such groups can be identified using clustering algorithms, techniques used in the multivariate data analysis. Kerala receives copious rain (average 3000 mm a year)each year. Therefore, in the present paper, an attempt has been made to derive the regional best fit extreme rainfall pattern for Bangladesh for the estimation of extreme rainfall quantiles. “The winds were strong too. No obstante, nuestros hallazgos explican el porqué la región oeste y sur de la cuenca del río Guayas está expuesta a problemas de sedimentación en la parte baja, producto de la capacidad erosiva de la lluvia en la parte alta y media de la cuenca. The four 3-month seasons are defined as follows: January–February–March (JFM), similar clusters are being merged early in the process, these distances are small, and they increase relatively little by, little as the clustering proceeds. As many 215 landslides have been reported. An autocorrelation test isapplied to test the independency of the data. Results have shown that the regions identified by both analyses are largely same. There follows a discussion concerning the main pluviometric characteristics of each region deduced from the best division. Two different algorithms are applied The pelagic influences are augmented by the high marine geochemical elements concentrations such as the chloride (Cl) and the sulfur (S). Then created agglomerative hierarchial cluster, Determination of Optimum Number of Clusters, square root of the variance of each variable of the new cluster formed by, e used. Find historical weather by searching for a city, zip code, or airport code. Furthermore, the density of rain gauges in Bangladesh is low and the quality of available flood data is poor. The rainfall pattern in the Western Ghats in Kerala is changing for the worse, according to an ongoing study by the Energy and Wetland Research Group of the Bengaluru-based Indian Institute of Science (IISc). More than 20,000 homes have been completely destroyed and 10,000 km of roads have been damaged. On an average, there is one raingauge station for every 3886.4 sq.km area. and regional homogeneity measures are applied to test homogeneity of regions identified by Ward's cluster method. Of Visitors : 8779745: Developed By: Pai said many conditions contributed in this year’s heavy rainfall. The increase of the brackish ostracod mark the settlement of a closed lagoon toward 768 a BP. The first municipality in the district formed in 1969, Malappuram serves as the administrative headquarters of Malappuram district.Divided into 40 electoral wards, the city has a population density of 1,742 per square kilometre (4,510 per square mile). Hence, attempts were made to fill up the missing rainfall values from the different data sources i. e. © 2008-2021 ResearchGate GmbH. (212) 419-8286 Oxygen isotopes values of Late Pleistocene are also 1.5‰ lower than modern precipitation. There are cluster groups where the annual rainfall is as high as 1.5 times and as less as half of average annual rainfall of Kerala as a whole. This study uses the annual maximum daily rainfall of 68 rain gauge stations. Moreover, the performances of the proposed weighting approaches for spatial clustering analysis are better than no-weight scenario in most modes according to the spatial patterns and homogeneity measurements. and consist of roughly the same number of stations. The situation improved slightly in 2016, but Kasargod was the only district to receive more than 2000 mm rainfall. The clusters are also characterized to see how they are distributed. The document contains the vehicle population report of Kerala from 01/04/2015 to 31/03/2016. In broad agreement with evidence from other paleoclimate investigations, the estimated noble gas recharge temperature (NGT) is lower than the present by about 5.5 °C. According to the Indian Meteorological Department data, Kerala received 1739.4 mm of rain from June 1 to August 8. Kerala experiences rainfall for around 120 to140 rainy days per year. In this study, groundwater residence time and recharge conditions of the deep aquifer of Sfax were investigated using environmental isotopes and noble gases. The southern districts of Kollam (943 mm) and Thiruvananthapuram (494 mm) were at the bottom of the table. The best fit distributions for all sub-regions are identified based on L-moments goodness of fit statistic. Mainland PR Average Rainfall (inches) PR/USVI Average Rainfall (inches) and Percent of Normal Decade 1940-1949 1950-1959 1960-1969 1970-1979 1980-1989 1990-1999 2000-2009 2010-2019 2020-2029 All rights reserved. “It is due to the inter-annual variability and changes in climatic conditions,” said D Sivananda Pai, who is the head of the Climatic Prediction Group at the India Meteorological Department in Pune. seasonal and annul rainfall series of Kerala State were constructed using monthly rainfall data of fixed network of 10 raingauge stations. For Further Communications Director , Karnataka State Natural Disaster Monitoring Centre, KSNDMC Campus, Major Sandeep Unnikrishnan Road,Near Attur Layout, Yelahanka Bangalore - 560 064, Karnataka, INDIA, Phone No :+91 080 67355000 Email : office@ksndmc.org, dmc.kar@gmail.com. Flood frequency analyses for seven sub-groups defined by Ward's clustering method are carried out using various frequency distributions based on index flood and L-moments approaches. According to the Indian Meteorological Department data, Kerala received 1739.4 mm of rain from June 1 to August 8. In [3], the entire region of Bangladesh is, the data, not defined previously, so that objects which are similar to each other in some sense are grouped into one, For this study, the entire state of Kerala, which occupies, is a small coastal State, situated in the southwest peni, a coastal belt of around 600km. Discordancy. At 665mm, Thiruvananthapuram received the lowest. Until August 8, Kannur had received the maximum rainfall (2265mm). New results are based on high-resolution micropalaeontological, sedimentological and geochemical analyses of several sediments cores coupled to new ¹⁴C datings. corresponding scores are utilized as input for cluster analysis. Try our corporate solution for free! The short dry season has little impact. The technique of principal component analysis and of cluster analysis has been applied to two sets of precipitation data in Switzerland, one containing 47 stations (1961–80), and the other 101 stations (1981–1993), with the aim of understanding more fully the spatial distribution of precipitation regimes. their interannual rainfall variability. Precipitation data by the Chuk-Woo-Kee has seriously decreasing trends but KMA observed data show significant increasing trends because of climate change effect. The process of clustering, ects that is, Euclidean distance between pairs of object is, nal time. analysis. La reducción de incertidumbre acerca de la agresividad de la lluvia en regiones costeras y andinas contribuye a la formulación de medidas de mitigación que contribuyan a la reducción de erosión y pérdida de nutrientes. Assuming the same number of clusters, the k-means method provides comparable spatial patterns with those of Ward's method. The second period showed the development of estuarine foraminifera coupled with the appearance of charophyte oogonia in addition to planktonic foraminifera, high Ti and Fe concentrations and dominant coarse fraction. The next year, 2015, saw a drought-like situation across the state. Using Ward's method, five sub-regions are recognized for Centroid series of each cluster and principal component series of each EOF have been compared to analyze the temporal patterns. Using the derived distributions, regional extreme rainfall quantiles were estimated, followed by geo-mapping in ArcGIS 9.2. Ildiko Pelczer, Judith Ramos, Ramón Domínguez, Fernando González. During the previous Southwest monsoon (2019), Kerala had received an actual rainfall of 2300.2 mm. The researchers are looking at the rainfall data of the past 100 years and the initial patterns are shocking. division, Jalavijnan Bhavan, Thiruvananthapuram. Homogeneous Zones in a Watershed Using Clustering Algorithms. Homogeneous regions are usually defined based on different methods and with consideration of a category of attributes. The disappearance of charophyte oogonia and planktonic foraminifera coupled with the enrichment of marine taxa marked the opening of our lagoon to the sea. With 1.9in over 8 days, you will experience some showers during your holidays. Moreover, in terms of cluster homogeneity, Fuzzy C-means algorithm outperforms the other clustering methods. It is decided that Ward method based on Euclidean distance, K-means, Fuzzy are the most likely to yield acceptable results in this particular case, as is often the case in climatological research. Monthly rainfall is calculated from these daily rainfall data using, MS Excel. Audio is not supported in your browser. It can also be concluded that extreme drought, which began in 2014, may be the beginning of another; the mega drought on the Korean peninsula based on the drought periodicity analysis. “The pressure gradient between the land and the ocean [due to differences in the ability to retain heat] was high,” he said. Besides three popular measures: K-means, Fuzzy and density, This study reveals homogeneous sub-regions over the poorly studied area of western equatorial Africa (10S–7N and 7E–30E). The spatial pattern of seasonal precipitation seems to be highly controlled by the wide latitudinal extent of the region and by the pronounced orographic relieves, and the time of occurrence of the maximum precipitation varies from spring in the north to winter in the south. Results are similar to those obtained by applying principal component analysis. Back to overview: India Meteorologists say that the rainfall data over the last six years do not suggest a visible pattern. Este estudio presenta un análisis espacial y temporal de la agresividad climática en la cuenca del río Guayas ubicada en la costa y Andes ecuatoriales. The stations are grouped based on the similarity of A month after the onset of the Southwest monsoon in Kerala, official figures said the state received normal rains with four of the six northern districts recording an excess in rainfall. This is visible across India.”. Homogene, Average annual rainfall is calculated for each cluster. Clustering of Regional Monthly totals of 141 stations covering the period 1955–1984 are used. Clustering is the process of dividing the area under consideration to a limited number of climatologically homogeneous zones, based on any hydrologic parameter. Rainfall data for a period of 53 years (1960–2013) at 32 stations representing the whole country was used. This process was probably responsible of the obstruction of the historic Boutria harbor and the abandon of the historic city. there is large variability in rainfall across Kerala. Then numbers of classe, computed by using ‘pdist’ function in MAT, square matrix of size 63 × 63, to save space and c, tree from the distance, which is known as dendrogram. March is the hottest month in Kerala with an average temperature of 29°C (84°F) and the coldest is June at 27°C (81°F) with the most daily sunshine hours at 9 in February. The flood control management at the watershed scale requires good quality flood data. After analysing the data for 115 years from 1901 to 2016, scientists have also established a decrease in southwest monsoon rain. The excess rainfall since the onset of monsoon in Kerala on June 1 has claimed 23 lives and damaged properties worth crores of rupees in 374 … The accuracy of results of quantile estimates are evaluated by using relative RMSE% and relative BIAS% through the use of Monte Carlo simulation. Applying the Precipitation Concentration Index (PCI), the intra-annual precipitation variability was also studied. Se determinó zonas homogéneas de precipitación mediante el método k-means. The average amount of annual precipitation is: 999.9 mm (39.37 in) It is found that the region can be grouped into seven clusters. Definiram-se 3 regiões homogêneas de precipitação, as quais foram validadas pelo índice de Silhouette. The best month to swim in the sea is in April when the average sea temperature is 30°C (86°F). Clustering of Regional, Raziei T., Bordi I., Pereira L. S. A Precipitation based region. The clustering process was conducted temporally and spatially using the Ward’s linkage method of Agglomerative Hierarchical Clustering (AHC). Results show that the northern and southern regions of western Iran are characterized by different climatic variability. It seems reasonable and advantageous to deal with a group of homogeneous stations rather than an individual station. Annual rainfall data for 2009 to 2012 were obtained from Venkatesan et al. The main source of monthly rainfall data of the 306 stations is National Data Center, IMD Pune. Los resultados indicaron dos regiones homogeneas predominantes, la primera ubicada al oeste en la zona costera y andina (85.2% del área de la Cuenca), con un índice de agresividad alto y muy alto, mientras que la distribución de la precipitación en la segunda región (Alta montaña) resultó de muy baja a baja agresividad. The climate is very warm here in this month. Malappuram (also Malapuram) (pronunciation) is a city in the Indian state of Kerala, spread over an area of 58.20 km 2 (22.47 sq mi). However, rainfall data of some of the 306 stations were not readily available in the published form or in the form of soft copy with IMD Pune. Furthermore, nine precipitation-derived parameters were used to regionalize climate in western Iran using principal component analysis and clustering techniques. The IMD has predicted heavy rainfall till Tuesday in the state. Join ResearchGate to find the people and research you need to help your work. The comparison of both methods indicates that cluster analysis is suitable to establish spatio-temporal patterns of seasonal rainfall distribution in Spain. The temperature in Kerala normally ranges from 28° to 32° C (82° to 90° F) on the plains but drops to about 20° C (68° F) in the highlands. The high spatial coherence which appeared is quite remarkable and confirms the usefulness of these techniques for the analysis of the spatial distribution of meteorological variables, even in a topographically complex area such as Switzerland. In 2013, all the state’s districts, except Thiruvananthapuram, received more than 1400 mm of Kannur, with 3119.4 mm, got the most rain. AMJ, JAS and OND and 4 sub-regions for JFM and annual data. After a peak in 2013, rainfall in the state dipped in 2014 and hit a low in 2015 before slowly rising in 2016, 2017 and 2018. Kerala so far received 2346.6 mm against normal of 1649.5 mm (above normal by 42%). A lot of rain (rainy season) falls in the months: May, June, July, August, September, October and November. Expected rainfall from 1stJune to 30stSeptember, 2016 for Kerala was 2039.6 mm while actual rainfall was only 1352.2 mm with -34% departure. Moreover, the density of these stations network is not sufficient for estimation of rainfall at ungauged regions. based clustering techniques are applied initially to decide the most suitable method for the identification of homogeneous region. And, ng Analysis is to place objects into groups suggested by, the southernmost part of India, is selected.

The Hence for, nloaded from the site named, Global Weath, ming that, there are ‘n’ elements to cluster. This study used the k-means method, widely employed to regionalize homogeneous areas of precipitation (Golian et al., 2010;Gómez-Latorre, 2015; ... where P is the number of clusters, N is the number of elements (gauging stations) in each cluster, M number of variables (months), x kij j-th month at the i-th gauging station in the k-th cluster x kj average value of the i-th gauging station at the j-th month in the k-th cluster. The actual rainfall received in Kerala during the South-West monsoon (June 1 to September 30, 2016) was 1352.3 mm as against the normal rainfall of 2039.7 mm in 2016 showing (-)34 percent departure from the normal, which was the highest in the country. Key words. The Highlands of Kerala, which is an area of major tourist attraction, enjoys a cool and invigorating climate the year-round. New data evaluating the relative sea level changes and sedimentary dynamics along the coast of Tunisia are presented. Initial estimates put monsoon-related losses at Rs 8,316 crore, he said. For regional frequency analysis, the L-moment method was applied. In recent years, 2013 saw the highest rainfall that Kerala has received (2561.2mm). Since the flood occurred in the Malayalam Era 1099, it is known as the “Great Flood of ’99”. Therefore, to minimize flood extremes, it is important to control the flood peaks at the upstream area through suitable watershed management practices. Kerala state is endowed with rich water resources like 44 rivers and two important, For the study, the main parameter required is the monthl, data of remaining 16 stations could not be received as they, these stations, Global Weather Data are used. Therefore, our results show that the methodology developed can be used to estimate precipitation in unmonitored locations in the TAHR. The average annual temperature is 27.5 °C | 81.5 °F in Pala. The process can be stopped just before these distances becom, some other reliable methods. All data correspond to the average monthly values of the last 20 years. Furthermore, a negative long-term linear trend in the north and a weak positive trend in the south of the study area have been detected though they are not statistically significant. Selection of attributes as representatives of the study region is an important aspect in clustering of a region, as is the importance degree (or determined weight) that each of these attributes can allocate to themselves. In all cases component scores are computed and their spatial distribution is discussed. Bangladesh is a flood prone country where huge damages take place every year. Results suggest that five spatially homogenous sub-regions can be identified characterized by different precipitation regimes. with k-means method. Den, different stages and the distance at whic. For which a statistical fact. Stability of the cluster is also tested based on nine validity indices. These factors resulted in heavy south west monsoon,” he said. The first and the second clusters include the northern part of Jordan characterized by high rainfall intensity, whereas the third group includes the southern part of Jordan and the last cluster represents the Badia and desert of Jordan country. ... Regionalization is a possible technique that can provide hydrological data at low cost. Kochi Temperature Yesterday. “The draught occurred because of El Nino,” said Dr D Sivananda Pai, Head of Climate Prediction Group at the India Meteorological Department in Pune. The south-west monsoons brought the most rainfall to the southern most Indian state of Kerala of over 2.5 thousand millimeters in 2018. In the month of december, maximum temperature is 88°F and minimum temperature is 81°F (for an average temperature of 85°F). Climate zones of Bangladesh are identified by using mathematical methodology of cluster analysis. The enrichment of the sediment in quartz grains coupled with the action of the current drift authorized the build-up of sandy spits and the genesis of the lagoon that preserve a rich assemblage of euryhaline ostracods and mollusks species. ... After analysing the data for 115 years from 1901 to 2016… The results of the regional multiple regression models showed that the annual mean precipitation was satisfactorily estimated. For this aim, the annual flood data obtained at the 117 gauging stations having data records of 31 years operated by the general directorate of electrical power resources survey and development administration (EIE) throughout Turkey are considered. From 1995 to 2005, the monthly rainfall data were collected from the daily weather reports published by the IMD, Trivandrum. Aplicaram-se testes não-paramétricos (Mann Kendall, Spermann e o Estimador Sem) para analisar as tendências de precipitação em cada uma das regiões formadas. Rafaela Nazareth Pinheiro de Oliveira Silveira. are more evident in JAS and OND. Thus, the objectives of this work are to i) identify homogeneous regions of precipitation in the Tocantins-Araguaia Hydrographic Region (TAHR) via the fuzzy c-means method, ii) regionalize and estimate the probability of occurrence of monthly and annual average precipitation using probability distribution models, and iii) regionalize and estimate the precipitation height using multiple regression models. Since the beginning of June 1, 2018, all the state’s districts received copious rainfall.
