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.
Where does convectional rainfall occur in India?
equatorial regions
It occurs generally in the equatorial regions of the world. Other regions of convectional rainfall are middle latitudes on summer days. Most of India’s rainfall is brought by southwest monsoon winds but you can also observe conventional rains in India, during hot summers in places like Delhi, Andhra Pradesh etc.
How the convectional rainfall takes place?
Convectional rainfall takes place when the sun’s energy heats the surface and so that water evaporates changing to water vapor. This moist and warm air then rises upwards and as it rises, it starts to cool. The air reaches a point known as condensation level where the water vapor condenses and turns back to liquid.
In which region convectional type of rainfall is high?
equatorial regions
The convectional rainfall is prevalent in equatorial regions. In these, the warm air rises up and expands then, reaches at a cooler layer and saturates, then condenses mainly in the form of cumulus or cumulonimbus clouds. In the equatorial regions, the precipitation due to convectional rainfall occurs in the afternoon.
Where is frontal rainfall received?
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.
Which type of rainfall does India receive?
The Indian subcontinent experiences two main types of rainfall- the southwest monsoon and the northeast monsoon.
What is convectional rainfall also called?
Convectional rainfall is also called 4 o ‘clock rain: Convectional rainfall is the result of high rate of evaporation. Then condensation takes place and rain falls. At mid-day, when the sun is at the highest position, the temperatures rise at the equator.
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.
Which type of rainfall is received around water bodies?
➢ This is the type of rainfall received in areas with lakes, water bodies and forests. Convectional rainfall usually falls in afternoons.
What season does convectional rainfall occur?
summer
Convectional rainfall occurs most frequently in regions that are extremely hot, either during the day, as in the tropics, or during the summer, as in temperate areas. When the sun’s energy heats the Earth’s surface, water evaporates to produce water vapor, resulting in convectional rainfall.
What is a conventional rainfall?
Convectional rainfall seems to occur when the heated air from the earth’s surface rises upwards along with the water vapor & gets condensed when it reaches a higher altitude. Here the clouds carrying the water vapor are not carried away by the wind and hence, it rains in the same place.
Why equatorial regions get convectional rainfall?
Convectional rainfall is mostly encountered in places that are close to the equator. This happens because equatorial region receives a lot of sunlight, compared to other places. Hence, it is easier for convection currents to form in these regions.
Does India have convectional rainfall?
Convectional type of rainfall is not prominent in India.
Which type of rainfall is received in hilly area?
Orographic or relief rain. When air is forced to rise over land, particularly higher ground such as hills and mountains, it cools as the pressure falls. Dry air cools at 9.8°C per 1000m it rises.
What is called 4 o’clock rain?
In equatorial regions, convectional rain occurs almost daily in the afternoons. It generally occurs at 4 pm thats why it is known as 4o Clock Rain.
Which type of rainfall is received in mountainous areas?
orographic rainfall
The type of precipitation in mountainous areas is called a relief rainfall or orographic rainfall.
Which type of rainfall is received by Mawsynram?
Orographic rainfall
Mawsynram is enclosed by hills on three sides. Mawsynram experiences Orographic rainfall as it is located on the windward side of Garohill. Mawsynram lies in the funnel-shaped depression caused by the Khasi range in Meghalaya. The Bay of Bengal branch of monsoons is trapped in it and causes heavy rainfall.
Which river is known as Indian rain?
The correct answer is Periyar. Periyar is a rain-fed river. The Periyar River is the longest river in the state of Kerala with a length of 244 km.
Which received highest rainfall in India?
Mawsynram
Mawsynram receives the highest rainfall in India. It is reportedly the wettest place on Earth, with an average annual rainfall of 11,872 millimetres (467.4 in), According to the Guinness Book of World Records, Mawsynram received 26,000 millimetres (1,000 in) of rainfall in 1985.
What type of rain is convectional rain?
Convectional rainfall is a kind of rainfall that occurs when the heated air from the surface rises along with the water vapour and gets condensed after reaching a higher altitude. Since the cloud carrying these vapours is not carried away due to the wind, the rain falls in the same place.
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.
