Rainfall is heaviest in the tropics - areas whose latitude is less than 23.5 degrees north or south of the equator and which receive a nearly constant amount of solar energy throughout the year. The water holding capacity of the air increases with rise in temperature. The equatorial region, which receives the most solar radiation and is very warm, contains extremely moist air. In addition, the northern trade winds meet the southern trade winds in this region to create the Inter-tropical Convergence Zone (ITCZ) - a band around Earth where moist tropical air is forced upward and heavy rain showers and frequent thunderstorms are produced. During the course of a year, the ITCZ migrates with the most direct angle of sunlight. When it is summer in the northern hemisphere, the ITCZ shifts towards the north; when it is winter in the northern hemisphere, the ITCZ shifts toward the south.
Rainfall is higher at the equator than the tropics because the equator receives more direct sunlight, resulting in warm air that rises and cools, leading to condensation and precipitation. This process, along with the influence of atmospheric circulation patterns like the Intertropical Convergence Zone, contributes to greater rainfall amounts at the equator compared to other tropical regions.
It is warmer than surrounding areas, causing more evaporation, causing more rain fall.
Solar radiation generates large amounts of heat near the equator, providing tropical regions with higher temperatures than most other regions on Earth.

What Regions have seasons that are marked by rainfall rather than temperature?
Regions near the equator typically have seasons that are marked by rainfall rather than temperature. These areas experience wet and dry seasons based on the movement of the Intertropical Convergence Zone (ITCZ), which brings periods of heavy rainfall. Examples include the tropical rainforests of the Amazon and Southeast Asia.
What is the angle at which the sun's rays strike the surface of Earth in the tropics?
In the tropics, near the equator, the sun's rays strike the Earth's surface at nearly a 90-degree angle, resulting in more direct and concentrated sunlight. This is why these regions receive more solar energy and experience higher temperatures compared to regions farther from the equator.
What region have seasons marked by rainfall rather than temperature?
The Tropics
How does rainfall in the eastern pacific compare to the rainfall in the western pacific?
Rainfall in the eastern Pacific is typically lower than in the western Pacific. The eastern Pacific tends to have a drier climate due to the presence of the cold California Current that limits moisture transport. In contrast, the western Pacific, near the equator, receives higher rainfall amounts due to the warmer ocean temperatures and greater atmospheric convection.
Why does Durban have a higher rainfall than Port Nolloth?
Durban receives higher rainfall than Port Nolloth due to its location. Durban is situated on the east coast of South Africa, where warm, moisture-laden air from the Indian Ocean brings abundant rainfall. In contrast, Port Nolloth is located on the west coast, where the prevailing winds bring dry air from the interior of the continent, resulting in lower rainfall.
Is the sun higher in hot countries?
Yes, the sun is always high in the sky in the tropics. At the equator the sun is always higher at noon than it ever gets in Britain.
What is one reason there is more species diversity in the tropics?
One reason for higher species diversity in the tropics is the stable environment, with consistent temperatures and abundant rainfall year-round, providing more niches for different species to thrive.
What Regions have seasons that are marked by rainfall rather than temperature?
Regions near the equator typically have seasons that are marked by rainfall rather than temperature. These areas experience wet and dry seasons based on the movement of the Intertropical Convergence Zone (ITCZ), which brings periods of heavy rainfall. Examples include the tropical rainforests of the Amazon and Southeast Asia.
Why is the salinity at seawater higher in subtropical regions than when it is at the equator?
Salinity in subtropical regions tends to be higher than at the equator because of the higher rates of evaporation in subtropical regions. As water evaporates, salt is left behind, increasing the overall salinity of the water. In contrast, the equator receives more rainfall, which dilutes the salt content in the water.
What tropics are in the Philippines?
No, the tropics are larger than the Philippines (they run round the whole planet north and south of the Equator. Thus the question should be :- "Are the Philippines in the tropics" The answer to that question is "Yes" (see the map of the tropics in the related link below.
Why does Scotland have more rainfall than Moscow?
because there is a difference from the equator length
What is the angle at which the sun's rays strike the surface of Earth in the tropics?
In the tropics, near the equator, the sun's rays strike the Earth's surface at nearly a 90-degree angle, resulting in more direct and concentrated sunlight. This is why these regions receive more solar energy and experience higher temperatures compared to regions farther from the equator.
Why are there more plants in the tropics than in the desert?
The tropics have consistent warmth, abundant sunlight, and consistent rainfall, providing ideal conditions for plant growth. In contrast, deserts have limited water and nutrients, harsh temperatures, and low rainfall, making it difficult for plants to survive and thrive. Therefore, the tropical climate is more favorable for plant diversity compared to the desert.
Which is longer- the equator or the Tropics of Cancer and Capricorn?
tropic of cancer
Is Egypt located in the tropics?
No, Egypt is not located in the tropics. It is situated in the northeastern part of Africa, with its northern coastline along the Mediterranean Sea. The Tropic of Cancer runs through the country, but Egypt's climate is predominantly influenced by its desert landscape rather than its position in the tropics.
Why do the tropics receive more energy from the sun than the polar regions?
The tropics receive more direct sunlight throughout the year because of their proximity to the equator, resulting in higher solar energy input. This is due to the curvature of the Earth, with sunlight more dispersed at the poles. Additionally, the angle at which sunlight hits the Earth's surface is more direct in the tropics, leading to greater energy absorption.
Why does the temperate zone have lower temperatures than the tropics?
The temperate zone receives less direct sunlight and has a wider range of temperatures due to its position between the tropics and the polar regions. The tilt of the Earth's axis also plays a role in creating seasonal changes in temperature in the temperate zone.
