Convectional rainfall When the land warms up, it heats the air above it. As the air rises it cools and condenses. If this process continues then rain will fall. This type of rainfall is very common in tropical areas but also in areas such as South East England during warm sunny spells.
What does conventional rainfall mean?
Convectional rainfall occurs when the heated air from the earth’s surface rises upwards along with the water vapour and gets condensed when it reaches a higher altitude. Here the clouds carrying the water vapour are not carried away by the wind and hence, it rains in the same place.
What are the characteristics of convectional rainfall?
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.
Does clouds give Convectional rainfall?
Cumulus clouds give convectional rainfall.
What is Convectional rainfall Where does it occur?
Convectional rainfall occurs in equatorial area. In this areas, the surface gets heated because of the sun’s heat and the air near it also get heated. As it get heated, it spreads and becomes lighter and moves upwards. Condensation of the water vapour takes place and results in rainfall.
Where does Convectional rainfall occur most?
Spot the difference between Convectional and Cyclonic rainfall.
| S. No. | Convectional Rainfall |

| 3. | These clouds bring rainfall which lasts for a very short duration. |
| 4. | Such rainfall is known as convectional rainfall which occurs mainly in the northern hemisphere, predominantly in the tropical regions. |
Where does Convectional rainfall occur in India?
equatorial
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.
What is Convectional rainfall in simple words?
Convectional rainfall occurs when the energy of the sun 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. This causes the air to expand and rise. As the air rises, it cools and condenses. If this process continues, rainfall will occur.
What are the 3 important features of convectional rainfall?
Explanation: CONVECTIONAL: This type os rainfall is characteristic of hot climates The Sun heats the ground and water evapores As water vapour rises, it cools When water vapour cools, it condenses and forms droplets that form clouds and fall to the Earth as rain. It does not rain on the other side.
Where does Convectional precipitation occur?
Convectional rainfall is widespread in areas where the ground is heated by the hot sun, such as the Tropics. This is why areas, such as the Amazon Rainforest, experience heavy rainfall most afternoons.
Does clouds give convectional rainfall?
What is convectional rainfall and how does it occur?
What is convectional rainfall? Convectional rainfall occurs when the energy of the sun 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. This causes the air to expand and rise. As the air rises, it cools and condenses.
What are the different types of rainfall?
Rainfall is of three different types namely – Orographic, Frontal (Cyclonic rainfall), and Convectional rainfall. Relief rainfall occurs very frequently near mountains beside the sea because of the ascent of air forced by the mountain barrier. The preconditions are that there must be sufficient moisture in the air.
What is the process of condensation and rainfall?
This process of condensation forms clouds high in the atmosphere. If this process continues, rainfall will occur. This type of rainfall is widespread in tropical areas (between the Tropic of Cancer and Tropic of Capricorn) but also in areas such as South East England during warm sunny spells.
What causes frontal rainfall to occur?
Causes for Occurrence of Frontal Rainfall A tropical warm air mass comes in contact with a cold air mass of polar region. The less-dense, lighter warm air is then forced to rise over the denser, cold air. It causes warm air to become cold.
