Typhoon

The troposphere contains water vapor, carbon dioxide, and other gases that trap heat radiating from the Earth's surface. Heat is transferred within the troposphere via conduction and convection. Convection leads to low pressure systems where tropical cyclones form over warm ocean waters near the equator. As warm, moist air rises over the ocean surface and condenses, it releases heat which causes more warm air to rise in a spiral pattern, developing the eye and wind speeds of a typhoon.

Troposphere is a part of the atmosphere where clouds are being formed.

This layer consists of water


vapor, carbon dioxide, methane, nitrous oxide, and others. These gases block some heat that is radiated
back from the ground. Through the process of conduction and convection, heat is being transferred from
one place to another. It is also through convection that a warm, moist air combines with cold air which
leads to the low-pressure system formation where tropical cyclones are initiated.
A typhoon is a very strong circular storm that originates
from warm oceans in the tropics near the equator and is
characterized by low atmospheric pressure, high winds,
and heavy rain.
How are typhoons formed? The process of
development before a storm or a cyclone form, starts
over a large body of water which is relatively warm with a
surface temperature of 26oC During condensation, heat
is released which warms the cool air, making the air
lighter and causing it to rise. As light air rises, more warm
air from the surface of the ocean moves into developing
storm and continues to grow, creating a wind spiral
pattern that spins around a calm area at the center of the
storm, called eye.
