Cyclones:
·
A Cyclone is a rapid
inward air circulation around a low-pressure(LP) area.
·
They are confined to the
area lying between 30° N and 30° S latitudes in the atmosphere.
Cyclones
in India:
·
Tropical cyclones in the
North Indian Ocean region develop during the pre-monsoon (April to June) and
post-monsoon (October to December) periods.
Conditions
for the formation of a tropical cyclone:
·
Large and continuous
supply of warm and moist air.
·
Strong Coriolis force
that can prevent the filling of low pressure at the centre.
·
Unstable condition that
creates local disturbances.
·
Absence of strong
vertical wind wedge which disturbs the vertical transport of latent heat.
Naming
of cyclones:
·
Countries affected by the
Arabian Sea and Bay of Bengal cyclones rotationally give names of cyclones in a
sequence.
·
The name ‘Midhili’ was
given by the Maldives.
