The identification of climate change impacts on rainfall (annual, seasonal and monsoon rainfall) was
studied using hundreds of rainfall data ranging from 1916-2006. The existence of trend in annual and
seasonal rainfall series was detected by Statistical Test, namely Mann-Kendall and the Difference of Two
Populations in monsoon series using Mann-Whitney.
The results of the test showed that annual and seasonal rainfalls in most of the studied area had decreased
where others had increased. The monsoon rainfall showed a significant difference in frequency distribution
particularly in the months March-April-May (MAM) and December-January-February (DJF).
