摘要

利用1982 - 2018年的降水和雨天数据,对年、季、月潜在趋势的意义进行了调查和评估。采用MannKendall检验和Sen’s斜率估计检验确定现有趋势方向,采用Sen’s斜率估计检验检测随时间变化的趋势方向和幅度。试验结果表明,塔希勒地区年降水量和阴雨日数呈增加趋势。季节降雨量和降雨日数在夏季呈减少趋势,在东北季风和西南季风季节呈减少趋势。月降雨量和阴雨日数趋势在7 ~ 11月呈增加趋势,5月呈减少趋势。MW21-MW24、MW30、MW33和MW43-MW45的周降雨量和雨日数趋势均呈减少趋势。

Rainfall and Rainy Days Trend Analysis in Miraj Tahsil of Sangli District
The study has been carried out to investigate and asses the significance of the potential trend on annual, seasonal and monthly basis using the data period between 1982 to 2018 for rainfall and rainy days. MannKendall test and Sen's slope estimate test were applied to identify the existing trend direction and Sen's slope estimator test were used to detect the trend direction and magnitude of change over time. The test results showed increasing annual rainfall and rainy days trend over the tahsil. The seasonal rainfall and rainy days showed decreasing trend for summer season and decreasing trend for northeast monsoon and southwest monsoon seasons. The monthly rainfall and rainy days trend showed increasing trend for July to November months and decreasing days for May month. The weekly rainfall and rainy days trend showed decreasing trend for MW21-MW24, MW30, MW33 and MW43-MW45.
