A map illustrates monsoon winds with rising air
currents over a hot land mass, showing how these
winds form.

Example: Southwest monsoon brings heavy rains to India in June-September

A map shows hot land with rising air currents,
explaining the formation of monsoon and trade winds.

Example: Warm equatorial air rises and cool polar air flows in
  • These wind systems affect weather patterns across continents .
Example: Monsoon failure causes drought in farming regions
