Which type of rain loke orographic cyclonic or convectional occurs in singapore
Answers
Cyclonic
Air flow around the center of a surface Low. In the Northern Hemisphere, this flow is counterclockwise as seen from above. (In the Southern Hemisphere, it is clockwise.) Also, any rotation in the direction of the Earth's rotation.
___________
cyclone
A low pressure region with its accompanying surface wind. Also a synonym for a tropical cyclone, or hurricane.
___________

On the basis of the sources for the uplifting action of the air, there are three categories of rainfall that may occur viz.
1. Convectional rainfall,
2. Cyclonic/Frontal rainfall.
3. Orographic/Relief rainfall.
Convectional rainfall: This type of rainfall occurs in Singapore.
This is moist air being heated from the ground surface.
Heating of the surface air make it to expands and rise to a higher level.
As the air rises, it comes in contact with cold air at higher level cools and becomes saturated and dew point temperature i.e. the temperature at which water vapor in the air condense gets saturated and then clouds forms.
By further cooling, precipitation takes place.
