Question 1 · 10 marks · 177 words written

What are the suitable conditions for the formation of a tropical cyclone? Also, bring out differences between a tropical and an extra-tropical cyclone.

Opening

Tropical cyclones are a natural phenomenon resulting out of pressure differences on land and may cause disastrous consequences and thus require to be studied effectively.

Suitable conditions for formation of Tropical Cyclone-

Body

(1) Core area of Low Pressure (2) Constant supply of water to give it energy (3) Coriolis force (due to Earth's rotation) to give it a spin (4) ambient air temperature to give it a particular spin

Close

Tropical CycloneExtra-tropical cyclone
(1) Originates in Tropical area (23 1/2 N - 23 1/2 S)(1) Originates in Temperate areas.
(2) Pressure differencet Coriolis force leads to its formation.(2) Air fronts owing to different air masses leads to their formation.
(3) Die on reaching landmass(3) No such constaint.
(4) Recent anomaly of cyclone not dying on land.(4) Climate change leads to high force cyclones

Thus, varied geographical locations and natural factors leads to differences in formation of the type of cyclones in an area.
