Intense LOW Pressure weather systems. These
generate extremely heavy rain, very strong winds and
storm surges.
Storms measure over 200-700km across.
They form over oceans and are fuelled by energy from
the oceans. They disipate (break down) once over land.…read more

Over the summer months deep oceans within the Tropics are
absorbing heat.
Once they reach 26.5c this triggers convection of warm moist air off
the sea surface = UP
To replace the air that has risen, new air is drawn in across the ocean
surface. This too will be forced to rise. This process is repeated several
hundreds of times = SUCK
This forms an area of Intense Low Pressure. As the air is warm it is able
to hold more moisture so huge cumulonimbus clouds develop and
strong winds.
As the earth rotates this causes the winds to spiral and rotate = SPIN
It is not 100% clear how they progress from a Tropical Storm to a
Revolving Tropical Storm…read more
