Trend and variability of monsoonal rainfall in different blocks of Chhattisgarh
An attempt has been done for the trend analysis and to find out the variability of monsoonal rainfall of different (146) blocks of Chhattisgarh. For that Long-term rainfall data of 25 years (1996-2020) was collected from the department of Agrometeorology, CoA, IGKV, Raipur (C.G.). for the trend analysis linear trend method was used with the help of TREND software. And Coefficient of variation was utilized to quantify the monsoonal variability. Results revealed that In Chhattisgarh plain zone out of 89 blocks, 3 blocks (Rajim, Mahasamund, Arang) observed a significantly increasing trend, and only 1 block (Champa) reported significantly decreasing trend of monsoonal rainfall. In the Bastar plateau zone out of 25 blocks 11 blocks observed significantly increasing trend of monsoonal rainfall. In the Northern hill zone out of 32 blocks, only 1 block (Jaspur) observed a significantly increasing trend and 11 blocks observed significantly decreasing trend of monsoonal rainfall. In Chhattisgarh Plain Zone, Monsoonal variability ranged between 13% (Malkharoda block) to 31% (Deobhog block). In Bastar plateau zone, Monsoonal variability ranged between 16% (Kondagaon block) to 28% (Sukma block). In Northern Hill Zone Monsoonal variability ranged between 15% (Pharsabahar and Duldula block) to 27% (Surajpur block).
