Answer. Only under specific conditions, development of tropical cyclones can be seen. To form three major conditions which are required are the presence of a low-pressure area in the ocean, the temperature of more than 27°C and the Coriolis force. Besides these pre-existing low focus areas and wind system along with proper space to spin and twist. It requires instability in the atmosphere and high humidity in the troposphere from lower to middle levels, etc. All these conditions help in the formation of tropical cyclones.
