What is aerosols and how does it affecting Indian Monsoon ?
An aerosol is a colloid of fine solid particles or liquid droplets, in air or
another gas. Aerosols can be natural or anthropogenic. Examples of natural
aerosols are fog, forest exudates and geyser steam. Examples of artificial
aerosols are haze, dust, particulate air pollutants and smoke.
Aerosols affecting Indian monsoon:
- Monsoon cloud gust into mainland due to pronounced difference in temperature
between land and the sea.
- GHG trap heat and overtime cause temperature to rise over the land and the sea.
- This affect the temperature gradients between them , over the decades leads to
raise in the frequencies of extreme rainfall or long rainless spells.
- The IMD last year recorded 2016 to be the hottest year in India has seen at
least 5 droughts years since 2002.
