SARAS 3 detects faint signals emitted by ... Read More...

Northeast India’s Extended Rainy Season

Feb 07, 2024

What causes the extended rainy season in northeast India compared to central India? The extended rainy season in northeast India, which lasts significantly longer than the central Indian monsoon season, is primarily influenced by the region’s unique geographical and climatic conditions. Factors such as the rate of temperature change with altitude in the troposphere, used as a proxy for the heat source over the region, play a crucial role. How do climate phenomena like ENSO affect northeast India’s rainy season? The El Niño and Southern Oscillation ... Read More...
