Why Tropical revolving storm curve away from equator?
Main reason is the Coriolis Force.
Coriolis force is caused due to rotation of the earth.
Coriolis force deflect the wind in right in Northern Hemisphere and left in southern Hemisphere.
Coriolis force is minimum at equator and as latitude increase, intensity increases as latitude increases and is maximum at poles.
Coriolis force deflect the TRS in right in Northern Hemisphere and left in southern Hemisphere and taking it away from equator.
For a formation of TRS, adequate value of coriolis force is required.
