What is frontal rainfall?
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.
Where do you find frontal rainfall?
Frontal rain occurs in places where air masses from tropical areas and polar areas meet. Britain receives much frontal rain. When hot air and cold air meet, air pressure is low, as air is rising. This weather system is called a depression and brings very changeable weather.
What are the stages of frontal rainfall?
What is frontal rainfall?
- Stage 1. An area of warm air meets an area of cold air.
- Stage 2. The warm air is forced over the cold air.
- Stage 3. Where the air meets the warm air is cooled and water vapour condenses.
- Stage 4. Clouds form and precipitation occurs.
How does frontal rainfall occur draw and explain?
Frontal Rainfall 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.
What is frontal and cyclonic rainfall?
Cyclonic or Frontal rain: This type of rainfall occurs when warm and cold air meets each other. Since warm air is lighter, it rises above the cold air. The rising air is then cooled beyond the saturation point resulting in heavy rainfall. Such rainfall lasts only for few hours.
Where does frontal rainfall occur in the UK?
The prevailing warm moist westerly winds mean that the west of the UK is more likely to receive rainfall from Atlantic weather systems, in the form of frontal rainfall. These weather systems usually move from west to east across the UK and as they do so the amount of rainfall they deposit reduces.
Which type of rainfall is experienced in the frontal region?
Cyclonic Rainfall – Major Characteristics A warm front and the cold front are the two parts of the front. At the warm front, the warm lighter wind increases slightly over the heavier cold air. This rain falls gradually for a few hours to a few days.
What is cyclonic rainfall in geography?
Cyclonic or Frontal rain: This type of rainfall occurs when warm and cold air meets each other. Since warm air is lighter, it rises above the cold air. The rising air is then cooled beyond the saturation point resulting in heavy rainfall. Rainfall is very heavy in the tropical cyclones.
How is cyclonic rainfall formed?
Cyclonic activity causes cyclonic rain and it occurs along the fronts of the cyclone. At the warm front, the warm lighter wind increases slightly over the heavier cold air. As the warm air rises, it cools, and the moisture present in it condenses to form clouds. This rain falls gradually for a few hours to a few days.
Is cyclonic rainfall the same as frontal?
Frontal (Cyclonic) Rainfall and its Features The layer separating them is known as a front. The front has two parts – the warm front and the cold front. At the warm front, the lighter warm air that is less dense usually forced to rise over denser cold air and thereby leading to cyclonic rain.
How does frontal rain occur?
Frontal rain occurs when two air masses meet. When a warm air mass meets a cold air mass, they don’t mix as they have different densities (a bit like oil and water). Instead, the warm less dense air is pushed up over the cold dense air creating the ‘front’.
What is the other name of frontal rainfall?
d) orographic rainfall is the correct answer .
