how cyclones are formed?
Answers
Answer:
cyclones are formed when two winds clashes
Answer:
The tropical cyclone is formed when a transfer of water vapour and heat from the warm ocean to the overlying air occurred primarily by evaporation from the surface of the sea. As we know that warm, moist air rises, it expands and cools, quickly and become saturated and released latent heat due to the condensation of water vapour. By this process, the column of air in the core of the developing disturbance is warmed and moistened. The temperature difference is formed between the warm, rising air and the cooler environment that causes air to become buoyant and enhance its upward movement.
If the surface of the sea is too cool then there will not be enough heat available and the rate of evaporation will be low to provide fuel to the tropical cyclone. Even the supply of energy will also be cut off due to warm surface water layer is not enough deep.
It happens because the tropical system modifies the underlying ocean. The sea surface becomes cool due to the falling of the rain from the deep convective clouds and the strong winds in the centre if the storm will further create turbulence. If this resulting mixing brings cool water from the below the surface layer to the surface, the fuel supply for the tropical system will be removed.
Let us tell you that the vertical motion of the warm air is not enough to initiate the formation of a tropical cyclone. Therefore, if the warm, moist air flows into a pre-existing atmosphere disturbance then only development will occur.
The rising air warms the core of the disturbance by releasing both latent heat and direct heat transfer from the surface of the sea and the atmospheric pressure in the centre of the disturbance becomes lower. As a result, the pressure decreases and causes the surface winds to increase, which in turn increases the vapour and heat transfer and contributes further to the rising of the air. The core becomes warm and the increased surface winds thus fortify or reinforce each other in a positive feedback mechanism.
