“…The increase of sea surface temperature due to changing climate has preceded vital rainfall pattern fluctuations [ 5 ]. Rainfall is an essential element in hydrological cycle, and its spatial as well as temporal variability is of major significance considering scientific and socioeconomic prospects [ 6 ]. Future changes in rainfall patterns are anticipated to increase and might cause more extreme rainfall events [ 7 ].…”

“…Although climate change is a broad area of research, the changing pattern of precipitation deserves urgent and systematic attention as it will affect the availability of food supply (Jain et al, 2013). Rainfall contributes significantly to the hydrological cycle, and the Spatio-temporal rainfall variability is crucial from both a scientific and a socioeconomic standpoint (Mehta & Yadav, 2021;Ramkar & Yadav, 2019). Precipitation changes used to have a substantial impact on society, and thus it's necessary to have up-to-date data to predict where precipitation is occurring and how much it varies (Gajbhiye et al, 2016;Yaduvanshi et al, 2015).…”

Changing trends captivate millions of analytical minds. It grabs much when the impact on human lives and properties is involved. The utmost concern is changing weather patterns, which led to a worse impact on the amount and distribution of the precipitation. Essentially, the challenge in several nations is to reach the whole population with adequate water per day. Even a country like India, which has thousands of rivers, streams, lakes, ponds, etc. unable to reach the whole population, as it depends on the uneven event, the Monsoon for its >80% annual rain during monsoon months (June-September). The Nation’s westernmost district, Kutch, which holds the title for the largest area-wise district in India, has been bearing from changing trends in rainfall for a long time. The rainfall distribution within the district is uneven and has experienced contrasting extreme events like drought and flood within consecutive years. The present study attempts to analyse the Spatio-temporal rainfall pattern for 58 years from 1961 to 2018 for the Kutch district using the IMD4 long-term daily gridded (High Spatial Resolution, 0.25° x 0.25°) rainfall dataset. In addition, the Mann-Kendall (MK) test and Sen’s slope method were performed to detect the trends and the magnitude of change over the studied period, respectively. The results indicate high rainfall variability during monsoon months in the north and northwest, while relatively moderate and low in the south and west parts of the district, respectively, and show an upward trend in monsoon rainfall at a 5% significance level in all the Taluka of the Kutch district.

“…But for this study, precipitation-based drought indices are considered (i.e., D%, SPI, and RAI) (Mehta & Yadav 2021a). The variability of the standardized precipitation index (SPI) was examined at 3, 6, 9 and 12-month intervals (Hajani et al 2014;Ramkar & Yadav 2019). By applying the Mann-Kendall test at the 5% significance level, trends of 3, 6, 9 and 12 monthly SPI outcomes were examined (Mehta & Yadav 2019).…”

Drought forecasting is being considered an important tool to help understand the rainfall pattern and climate change trend. Drought is a prolonged period of months or years in which an area, whether surface water or groundwater, becomes insufficient in its water supplies. Drought is considered as most difficult but least known environmental phenomenon, impacting more persons than any other. There are several indices used to classify droughts. For this study, precipitation-based drought indices are considered (i.e., SPI, RAI and Percentage Departure of Rainfall). The objective of the research is to examine and determine the possible rainfall trends over the Jalore district of South-West Rajasthan in Luni river basin. In this research, trend analysis using the rainfall data from the years 1901 to 2021 was carried out on monthly, seasonal and annual basis. To define the current trend path, the Mann-Kendall test and Sen's slope estimator test were used. In order to detect the trend and its change in magnitude over a particular period of time, Sen's slope estimator was used. During the southwest monsoon, declining rainfall leads to short-term meteorological droughts, which have severe effect on the agriculture sector and Jalore district's water supplies, while rising rainfall during other seasons tends to mitigate the severity of drought. The result of research reveals that there is rise of pre-monsoon and post-monsoon rainfall, but it also depicts a fall in the annual rainfall which reflects in reduced Winter and S-W monsoon rainfall.
