• Tropical storms with very strong winds wih speeds of at least 119km/hr

• Monsoon winds that blows across Asia and speeds

• Cool sea and ocean temperatures that is around 20°C to 27°C

The (a)   of the typhoon is a low pressure area with very calm weather, clear skies and light winds. This is the centre of the typhoon.

Why do typhoons weaken when they approach the land?

• Because once they reach the land, there are not able to gather enough wind and heat.

• Because once they reach the land, they lose their supply of warm moist air from the sea or ocean.
