Why do equatorial regions have high temperature throughout the year and a small range in temperature?

Rainforests are located in the equatorial climate region. They are hot and wet all year round – this creates a humid climate. The annual rainfall is high as it rains almost every day. The temperatures are constant all year round – the temperature range is usually only a few degrees.

Which region has high diurnal range of temperature?

The region with a high diurnal range of temperature is a tropical desert region. Explanation: These deserts are in southern and northern hemispheres, mainly between 5 and 30 degrees of latitude. The tropical desert is an intense environment: it is the earth’s driest and hottest location.

Why does temperature decrease with altitude?

As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands), and the temperature decreases.

Why are temperatures high in equatorial regions?

The sun-rays fall directly and there is more rainfall in the equatorial region. This is the reason behind which are high temperatures and humidity in this region.

Which region experience less variation in diurnal range of temperature?

Differences in variation High desert regions typically have the greatest diurnal-temperature variations, while low-lying humid areas typically have the least.

Which part of the India does experience the highest diurnal range of temperature and why?

The Thar desert area of Rajasthan experiences the highest diurnal range of temperature because it is in the interior part where the temperature differences are very high.

Why is it colder in higher altitudes?

High-altitude locations are usually much colder than areas closer to sea level. This is due to the low air pressure. Air expands as it rises, and the fewer gas molecules—including nitrogen, oxygen, and carbon dioxide—have fewer chances to bump into each other.

What is the diurnal range of temperature in equatorial region?

60C to 100C.
The equatorial type of climate experiences a diurnal range of 60C to 100C. It is because while the temperature during the day may become hot due to the vertical rays of the Sun, the nights may cool down due to heavy downpour during afternoon or evenings.

What causes diurnal temperature variation?

Diurnal temperature variations are greatest very near Earth’s surface. Both these extreme daily temperature changes were the result of sharp air-mass changes within a single day.

Why does the rainfall decrease from east to west in northern India?

Rainfall decreases from the east to the west in Northern India because there is a decrease in the moisture of the winds. Consequently, states like Gujarat and Rajasthan in western India get very little rainfall.

What are the characteristics of an equatorial climate?

Characteristics of Equatorial Climates. The annual temperature range may be as low as 3 degrees Celsius. The diurnal or daily temperature range (the difference between the highest temperature in the day and the lowest temperature at night) is usually greater. Humidity is usually very high.

Why does the equatorial region receive maximum amount of sunlight?

Since mid-day sun is almost overhead through­out the year and there is little difference between the lengths of day and night during the year and hence the equatorial region receives maximum amount of insola­tion which causes uniformly high temperature through­out the year as the average monthly temperature is always more than 18°C.

Why do tropical regions have a high diurnal temperature variation?

In addition to the fact that tropical regions have a moist climate (and hence the diurnal temperature variation is moderated, as the previous post mentions), there is also the fact that the sun angle remains relatively high throughout the year, maximizing the intensity of the solar radiation.

What happens when the moist air from equator reaches 30° latitude?

When the moist air from equator reaches 30° latitude it encounters Coriolis force due to earth’s rotation and starts to descend down. Normally, moist temperature varies by 6 °C per km while dry air varies by 10 °C per km of travel.
