How three characteristics of convectional rainfall?
Convectional rainfall occurs when the ground surface becomes heated by the sun, causing air near the surface to warm, rise, and cool at higher altitudes. It is typically associated with cumulonimbus clouds that produce localized, heavy downpours. Convectional rainfall is common in tropical regions with high temperatures and humidity, leading to rapid and intense rainfall.
Why is surface salinity of an ocean higher in the subtropics than in the equatorial regions?
Surface salinity is higher in the subtropics than in the equatorial regions because of the combination of high evaporation rates and low precipitation levels in the subtropics. This leads to a concentration of salt in the surface waters as water evaporates, while the equatorial regions receive more rainfall that dilutes the salinity.
Why does it rain every afternoon in the equatorial region?
It rains every afternoon in the equatorial region due to the combination of high humidity levels, warm air expanding and rising, leading to cloud formation and condensation. This process, known as convectional rainfall, is common in equatorial regions because of the consistent warm temperatures and abundance of moisture.
Which rainfall is known as the 4 o'clock rainfall?
Convectional Rain:This type of rain is common in the hot and wet tropical rain forests of central Africa, Amazon basin of South America and the islands of south-east Asia. Continuous heating of the earth in the day causes hot convectional currents to raise Water keeps on evaporating and rising up. On reaching the upper layers of the atmosphere they cool, condense and from cumulonimbus clouds. In the late afternoon the clouds burst into a heavy downpour, often accompanied by thunder and lighting. It usual occurs at about 4 pm, so convectional rain is called 'four o'clock rain' and occurs daily in the equatorial regions.
What is Convectional rains?
Convectional rainfall occurs when the energy of the heats the earth’s surface and causes water to evaporate changing to water vapor which then forms clouds and rain comes down.
What is the average rainfall in equatorial regions?
The average annual rainfall in equatorial regions is around 80-400 inches (200-1000 cm). These regions experience high levels of precipitation due to their proximity to the equator, where warm ocean waters fuel intense convection and cloud formation.

It is typically associated with cumulonimbus clouds that produce localized, heavy downpours. Convectional rainfall is common in tropical regions with high temperatures and humidity, leading to rapid and intense rainfall.
Where does convectional rainfall take place?
Convectional rainfall typically occurs in tropical and subtropical regions where high temperatures lead to intense surface heating. This heating causes air to rise rapidly, cool, and condense, forming clouds that produce heavy rainfall. It is commonly observed in areas such as the Amazon Basin, central Africa, and parts of Southeast Asia during the warm months. Additionally, convectional rainfall can also occur in some temperate regions during summer.
Are equatorial region and monsoon region same?
No, equatorial regions are defined by their proximity to the equator and experience a hot and humid climate year-round. Monsoon regions, on the other hand, are characterized by a seasonal shift in wind direction that brings heavy rainfall. While there can be overlap between equatorial and monsoon regions, they are distinct in terms of their climate patterns.

How much rainfall Africa gets?
Africa is a continent with a wide variety of climatic regions ranging from the Sahara desert to the equatorial rain forest. No single meaningful rainfall number is available.
What is the humidity at the equatorial low?
The humidity at the equatorial low is generally high due to the warm and moist air rising at the equator. This rising air results in the formation of rainforests and often leads to frequent and heavy rainfall in equatorial regions.
What is convectional rainfall found mainly along the equator?
Convectional rainfall occurs mainly along the equator due to the intense heating of the sun, which causes air to rise rapidly, cool, and condense into rain clouds. As the warm air rises, it cools and releases its moisture, resulting in heavy rainfall in tropical regions near the equator. This process is known as convection, where warm air expands and rises, creating localized areas of low pressure.
Which African countries have rain all year?
Countries near the equator in Africa, such as Gabon, Equatorial Guinea, and parts of Congo, experience rainfall throughout the year due to their tropical rainforest climate. These regions have high humidity and are known for consistent and heavy rainfall.
