In the recent past, there were extensive floods in the Western Himalayan region (WHR) due to continuous long spells of heavy rainfall for 3–4 days that caused a huge loss in life and property over the region. WHR is a data sparse region, with limited meteorological stations having a continuous long spell of daily precipitation data. In the present study, spatial and temporal variability of seasonal as well as annual precipitation, precipitation days and maximum accumulated daily, 2 days, 3 days, 4 days and 5 days precipitation over WHR is considered by using daily precipitation data of 18 meteorological stations of the region. Out of 18 meteorological stations, five stations have continuous data from 1901 to 1980 and remaining 13 stations data is considered for their common period from 1981 to 2014. Accordingly, the analysis is carried out in two parts, first for 1901–1980 (for 5 stations) and second for 1981–2014 (for all the 18 stations). The analysis suggests high variability in the spatial and temporal distribution of seasonal as well as maximum accumulated daily to 5 days precipitation over WHR. In general, increasing trends in maximum accumulated precipitation in lower altitude stations and decreasing trends in higher altitude stations are observed in monsoon season and vice-versa in the winter season during the period 1981–2014. The increase in maximum accumulated daily to 5 days precipitation is up to 9.7 mm per decade during 1901–1980 and is up to 45.5 mm per decade during 1981–2014 in monsoon season in lower altitude stations. Thus, the increase in maximum accumulated precipitation during monsoon season becomes manifold during 1981–2014 as compared to the period 1901–1980.

近来，由于连续 3-4 天的长时间强降雨，西喜马拉雅地区 (WHR) 发生了大面积洪水，给该地区的生命和财产造成了巨大损失。WHR 是一个数据稀少的地区，气象站有限，每天都有大量连续的降水数据。在本研究中，利用 18 个气象站的日降水资料，考虑了 WHR 的季节和年降水量、降水天数和最大累积日、2 天、3 天、4 天和 5 天降水的时空变异性。该区域。在 18 个气象站中，有 5 个站具有 1901 年至 1980 年的连续数据，其余 13 个站的数据考虑为​​ 1981 年至 2014 年的共同时期。因此，分析分两部分进行，第一部分是 1901-1980 年（5 个站），第二部分是 1981-2014 年（所有 18 个站）。分析表明，WHR 的季节性和最大累积每日至 5 天降水的空间和时间分布具有高度可变性。总的来说，1981-2014年间季风季节观测到的最大累积降水量在低海拔站有增加趋势，在高海拔站有减少趋势，反之亦然。1901-1980 年期间最大日累积至 5 天降水量增加高达每十年 9.7 毫米，1981-2014 年在低海拔站的季风季节增加高达 45.5 毫米每十年。因此，
