Spatiotemporal variability of weather extremes over eastern India: evidences of ascertained long-term trend persistence and effective global climate controls

The present study acknowledged climate variability induced periodic variation in localized extreme weather event occurrences under diverse agro-eco regions of Eastern Himalayas India during the past five decades. widespread rise warm nights (TN90p; 0.31–1.67 days year?1), reduced daily rainfall intensity (SDII), and changes other extremes, viz. temperature precipitation signified clear signals on regional atmospheric warming across eastern India. agro-ecological extended Bramhaputra valley coastal belts south Bengal experienced most persistent shifts while upper Himalayan range from North to Arunachal Pradesh steepest decline average absolute quantitative estimates extremes over Together with El Niño La Niña events, large-scale global circulations particularly expansion warmer Pacific Warm Pool (PWP) Atlantic Meridional Mode (AMM) contributed dynamics monthly annual time scale Our findings will be useful for better understanding climatology, designing, successful implantation location-specific suitable agricultural policies towards change adaptation near future.
