Frontal Rainfall is caused by cyclonic activity and occurs along the fronts of a cyclone. when two masses of air of different temperatures meet, they do not mix easily due to temperature and density variations. Fronts are the areas where the rainfall takes place, hence, also called frontal rainfall.
What does frontal rainfall mean?
Frontal rainfall occurs when a warm front meets a cold front. The heavier cold air sinks to the ground and the warm air rises above it. When the warm air rises, it cools. The cooler air condenses and form clouds. The clouds bring heavy rain.
Why is it called cyclonic rainfall?
Cyclonic rainfall is occurs when air mass rise up due to pressure difference. When there is the formation of a low-pressure area, air from the other surrounding spaces flows to less pressure zone. It is phenomenon forces warm and colder air to meet. … Such rainfall is called Cyclonic Rainfall.
What is cyclonic and frontal rainfall?
Cyclonic rainfall, also known as frontal rain, is caused when two air masses of different temperatures meet. Warm air and cool air don´t mix, as they have different densities. As the warm air rises over the heavier cool air, it cools and creates a front; clouds form and produce rain.
How does frontal rainfall occur draw and explain?
This rainfall occurs when a warm, tropical air mass comes in contact with a cold, polar air mass. It is very common in Britain and Ireland. Because the air is in the warm front, then it rises over the cold front. The air is cooled and so condenses to form a stratus cloud.
Is frontal rainfall and cyclonic rainfall the same?
Frontal precipitation is the result of lifting of lighter warm moist air over more dense cold air. Generally, most storms in the Great Plains states are cyclonic. Convective precipitation results from the lifting or upward movement of air that is warmer and lighter than its colder denser surroundings (figure 3).
What is the cyclonic rainfall?
Cyclonic rainfall is also known as frontal rainfall. Explanation. This sort of precipitation happens when warm and cold air meets one another. Since warm air is lighter, it transcends the virus air. The rising air is then cooled past the immersion point bringing about weighty precipitation.
Which type of cyclonic rainfall is called frontal rainfall?
frontal rainfall is caused by cyclonic activity and occurs along the fronts of a cyclone. when two masses of air of different temperature meet, they do not mix easily due to temperature and density variations. the imaginary line of separation between these two masses of air is called a front.
Where does cyclonic rainfall occur?
Cyclonic rainfall occurs in tropical as well as temperate regions. When warm and cold air masses converge, condensation and precipitation takes place on the boundary between warm and cold air masses called as Frontal rainfall.
What is the difference between cyclonic and convectional rainfall?
1. Convectional rainfall is a type of rainfall that involves the formation of convection currents. The cyclonic rainfall, on the other hand, is caused due to cyclones. … This rainfall occurs when the temperature gets high and the warmer air rises up in the atmosphere.
Where does cyclonic rainfall occurs in India?
The low-pressure conditions over northwestern India, which get transferred to the Bay of Bengal, are associated with the occurrence of cyclonic depressions, which originate over the Andaman Sea.
Why is frontal rainfall common in the UK?
The British Isles are affected by a number of different air masses . … As the warm air is forced to rise it cools. Also, the warm air is in contact with the cold air along the fronts, and this also cools. Condensation occurs and clouds form.
