Sudden Stratospheric Warming
• Southern India received excessively heavy rainfall (ten times the normal) in the beginning of 2021.
• This winter rain, according to the scientists, is due to sudden stratospheric warming that occurred in the Arctic region.
About Sudden Stratospheric Warming:

• It is preceded by a situation where the polar jet stream of westerly winds in the northern hemisphere is disturbed by natural weather patterns. This is usually addressed as the polar vortex.
