Results are similar to those obtained by applying principal component analysis. On average, January is the driest month. AMJ, JAS and OND and 4 sub-regions for JFM and annual data. Kerala receives copious rain (average 3000 mm a year)each year. Pai said many conditions contributed in this year’s heavy rainfall. 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. 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. The wettest month is June with an average of 341mm of rain. 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. The climate is very warm here in this month. In all cases component scores are computed and their spatial distribution is discussed. In this study, groundwater residence time and recharge conditions of the deep aquifer of Sfax were investigated using environmental isotopes and noble gases. 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 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). “Reduction in monsoon rainfall over Kerala is mainly driven by both the weakening of upper and lower level monsoonal circulations,” said S Abhilash of the Department of Atmospheric Sciences at the Cochin University of Science and Technology, one of the authors of the research paper. (212) 419-8286 Three major periods were identified. Five Agglomerative Hierarchical clustering measures based on mostly used six proximity measures are chosen to perform the regionalization. All data correspond to the average monthly values of the last 20 years. season/sub-region is also provided and compared. Include a date for which you would like to see weather history. The accuracy of results of quantile estimates are evaluated by using relative RMSE% and relative BIAS% through the use of Monte Carlo simulation. Clustering of Regional The pelagic influences are augmented by the high marine geochemical elements concentrations such as the chloride (Cl) and the sulfur (S). 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. The The climate is tropical in Pala. From 1995 to 2005, the monthly rainfall data were collected from the daily weather reports published by the IMD, Trivandrum. 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 spatial distribution of the seasonal and annual precipitation was analyzed in western Iran using data from 140 stations covering the period 1965–2000. The time variability of dry and wet periods in the identified sub-regions was analyzed using the Precipitation Index (PI) and the existence of any long-term trend was tested. Eight other districts received more than 2000 mm.
