Introduction

Cyclones are large areas of low pressure & revolving air & thunderstorms

12 words

Main Body

Ideal conditions required:

Sea surface temp ~27°C or above
Large area of low salinity
Low wind shear
Upper air divergence
Existence of low pressure region

Factors for increased activity over Arabian sea

1Early withdrawal of monsoon reduce Vertical wind shear
2Rising sea surface temperature due to climate change
3Increased glacial melt of rain providing greater amount of fresh water
4Presence of Low pressure trough from bay of bengal
5Greater summer of shade winter enhance cyclone season in October-November
6Weakening tropical Jet stream enome conditions for cyclones.

  • Clearly defines what cyclones are
  • Lists ideal conditions required for cyclone formation
  • Links climate change to cyclonic activity
  • Includes specific temperature thresholds (27°C)
  • Mentions seasonal patterns (October-November)
