Occurs in the coastal areas in the tropics
Bring heavy rainfall and strong winds speed about 200 km per hour
Accompanied by thunder and lightning
In Japan, China & the Philippines are called Typhoon
In Bangladesh and Australia is known as Tropical Cyclones
Atlantic areas they are called Hurricanes
THE FORMATION OF TROPICAL STORM
Develop over the warm oceans when the surface temperatures exceed 27◦C
When air over the sea get heated, it expands and rises very rapidly.
This create an area of intense low pressure.
Warm moist air rises to a great heights, condensing to form clouds and rain.
Air from the surrounding higher pressure area rushes inward in a spiraling manner to replace the rising warm air.
The air spin in at speed of about 200 km per hour, absorbing large amount of moisture and forming cumulonimbus clouds and heavy rains.
The cold air then sink, the centre of the storm is called the eye in area of calm weather marked by clear skies
THE EFFECTS OF TROPICAL STORM
Destroy life – especially in the populated areas
Destroy property- uproot trees, destroy crops and houses
Storm surges- when strong winds raise the ocean surface into a giant waves and destroy coastal settlements and flood large areas.
Flood – a covering water over land which is normally dry which are related to weather.
a) continuous rain- a longer period of rain, when the water cant seep inside the ground and more runoff
b) snow melt- snow melt and increase the volume of water in the river and runoff
c) storm surge
