LIFE CYCLE OF CYCLONIC STORMS
A low-pressure area when formed over warm sea conditions is likely to intensify in to
a depression. Depending upon the heating of ocean, the energy is supplied to a
depression. It further
strengthens the low
pressure area in to deep
depression. with supporting
conditions, the cyclogensis
starts by further sucking the
moist warm air feeding
more energy to the system.
The system organizes in
the form of cyclone and
further intensifies
depending upon the
prevailing wind and
temperature conditions. a
typical storm track is shown
in the given figure. The

storm brewing in sector A7 as
depression and intensifies as cyclone as it moves to sector A6. In sector A5, it further
intensifies to severe cyclonic storm until land fall in sector A4. It continues to remain
for sometime as severe cyclonic storm overland as it continues to draw energy from
ocean through its coast lines. When the system is totally on land, the energy feed is
cut off and the system weakens to cyclonic storm and continues to maintain in sector
A3 and part of A4 due to its inherent energy. The storm further weakens to
