4 o’clock rain is another name for convectional rainfall. The high evaporation rate causes convectional rainfall. Then condensation occurs, and rain begins to fall.
What is other name of convectional rainfall?
4. Such rainfall is known as convectional rainfall which occurs mainly in the northern hemisphere, predominantly in the tropical regions. This type of rainfall is known as cyclonic rainfall and generally occurs in the coastal areas of the world.
Why is it called convectional rainfall?
Convectional rainfall occurs when the energy of the sun (or insolation) heats the earth’s surface and causes water to evaporate changing to water vapor. This warm, moist air then rises, and as it rises, it cools.
What is the other name for frontal rainfall?
Cyclonic or frontal rainfall
Cyclonic rainfall is also called frontal rainfall because it occurs along the fronts of a cyclone. Frontal rainfall occurs when warm air and cool air meet each other. Warm air is lighter than cool air. So, the warm air rises above the cool air.
What is another name for cyclonic rain?
Frontal
Frontal (or Cyclonic) Rain is caused by cyclonic activity and it occurs along the fronts of the cyclone. It is formed when two masses of air of different temperature, humidity and density meets.
Is monsoon convectional rainfall?
Convectional rains occur during pre-monsoon summer in India.
What is conventional rainfall type?
Convectional Rainfall – Major Characteristics
As the air rises, it expands and drops the temperature and subsequently, condensation takes place and cumulus clouds are formed. Heavy rainfall with lightning and thunder takes place which does not last long. Such rain is usually in the summer or the hotter part of the day.
What is convectional rainfall answer?
Convectional rainfall occurs when the sun’s energy heats the surface of the Earth, causing water to evaporate to form water vapour. When the land heats up, it warms the air above it, causing it to expand and rise. As the air rises, it cools and condenses.
What is a convective rainfall?
Convection Precipitation. Convective precipitation results from the lifting or upward movement of air that is warmer and lighter than its colder denser surroundings (figure 3). Typically, on a hot day the ground surface becomes heated, as does the air in contact with it.
What is called cyclonic rainfall?
Cyclonic rains are caused when the warm moist air comes in contact with cool dry air. At the end of summer, the air above the water heats up and rises creating an area of low pressure. So, the high pressure cold air starts rushing in.
What are three types rainfall?
There are three types of rain that are Convectional rainfall, Orographic or relief rainfall Cyclonic or frontal rainfall.
What is low rainfall called?
To a meteorologist, a drought is a prolonged period when precipitation is less than normal. To a water manager, a drought is a deficiency in water supply that affects water availability and water quality. To a hydrologist, a drought is an extended period of decreased precipitation and streamflow.

Where does Convectional rainfall occur?
Equatorial region
Convectional rainfall occurs in the Equatorial region. The Equatorial region receives a greater amount of solar radiation. When the energy of the sun heats up the earth’s surface, there is an evaporation of water, forming water vapour. The warm air above the land surface expands and rises.
What type of rain is monsoon?
The summer monsoon is associated with heavy rainfall. It usually happens between April and September. As winter ends, warm, moist air from the southwest Indian Ocean blows toward countries like India, Sri Lanka, Bangladesh, and Myanmar. The summer monsoon brings a humid climate and torrential rainfall to these areas.
What season is convectional rainfall?
It occurs generally in the equatorial regions of the world. Other regions of convectional rainfall are middle latitudes on summer days.
Is monsoon rainfall orographic rainfall?
Rainfall in India through Southwest monsoon and northeast monsoon is orographic.
Who is convectional rainfall caused?
Convectional rainfall occurs when surface of the earth is heated up by the sun. The warm surface also heats up the air. As air rises it cools down and begins to condensate. Further rising and cooling causes a large amount of condensation to occur and rain is formed.
What is convectional type?
A convectional type of rainfall is experienced in the equatorial region. Air near the equatorial region is heated more due to high-intensity solar radiation. It expands, becomes lighter and moves in the upward direction in the form of convectional currents. The rising air cools down.
