Key Drivers Behind Extreme Weather Events

  • El Niño–Southern Oscillation: It is a climate pattern involving changes in sea surface temperature in Central and Eastern Tropical Pacific Ocean.
  •  Indian Ocean Dipole: It is the difference in sea surface temperature between the western Indian Ocean and the eastern Indian Ocean.
  • Arctic Oscillation:  It is a see-saw shifting of atmospheric pressure between the Arctic and the mid-latitudes of the North Pacific and North Atlantic. It affects weather throughout the northern hemisphere. 
  • Asian Monsoon:  It is a seasonal reversal in the direction of the prevailing winds. It is a key driver of seasonal variation in South and East Asia. 
  • Atmospheric Rivers (Ars) Over Asia: 
    • They are long, narrow, shallow, and transient corridors of strong horizontal water vapor transport typically associated with a low-level jet stream ahead of the cold front of an extratropical cyclone. 
    • They are active over mid-latitude oceans and play a crucial role in the global Equator-to-Pole water vapor transport.
