Why is Convectional rainfall common in certain regions of the world?
Because it is the mid-latitudinal region which experiences other endogenous and exogenous forces from certain coastal areas beyond coastline. Thus, convectional rainfall is most common in certain regions of the world.
What type of rainfall occurs in Singapore and why?
Convectional type of rainfall occurs in ‘Singapore’.
Convectional type rainfalls are a typical moist air along with warmed rainfalls where they got heated by the ground surface.
Why is Convectional rainfall common?
Convectional rainfall occurs when the energy of the sun heats the surface of the Earth, causing water to evaporate to form water vapour. … 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.
Why is it so rainy in Singapore?
In its neutral phase, winds blow from the western end of the Indian Ocean basin towards the east, keeping warm water pooled around Singapore and the maritime continent. … The warmer pool fuels the formation of rain clouds, and results in heavier-than-usual rainfall over Singapore.
What is Convectional rainfall and how Convectional rainfall occurred explain?
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. … As the clouds continue to grow the weight of the water droplets can eventually lead to precipitation.
What is Convectional rainfall?
Convectional rainfall is a type of rainfall that involves the formation of convection currents. … This rainfall occurs when the temperature gets high and the warmer air rises up in the atmosphere. On expansion, this air cools down and clouds are formed, which are generally cumulus clouds.
What type of rainfall is Singapore prone to in the afternoon?
Rain showers and thunderstorms are common during midday in this season, dropping the rainfall average to less than 7 inches in July. Thunderstorms usually last for half an hour, and squall lines are usually experienced at night over Sumatra and hit Singapore early in the morning.

Which part of Singapore rains the most?

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.
Why does Convectional rainfall occur in rainforests?
The roots of plants take up water from the ground and the rain is intercepted as it falls – much of it at the canopy level. As the rainforest heats up, the water evaporates into the atmosphere and forms clouds to make the next day’s rain. This is convectional rainfall.
Why does Convectional rainfall occurs in the afternoon?
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 rainiest month in Singapore?
April is the warmest month, January is the coolest month and November is the wettest month. Singapore lies between Malaysia and Indonesia, with a total area of 693 sq km and a coastline of 193 km. It consists of one main island and several other surrounding islets.
Why is it raining in Singapore July 2021?
REVIEW (1 – 31 July 2021)
Thundery showers fell over parts of the island between the late morning and afternoon on most days due to strong day-time heating of land areas. Large scale convergence of winds over Singapore and the surrounding region brought moderate to heavy thundery showers on a few days.
Why is Singapore weather so hot?
Singapore has already experienced warming higher than the global average because of the urban heat island effect – a phenomenon of urban structures trapping heat in the day and releasing it at night. … In contrast, global temperatures have warmed by about 1.1 deg C from pre-industrial times, which ended around 1850.
