What is the equator in the world and know the nature of the climate of the tropics ??

equator

It is an imaginary line developed by specialized scientists, as this line wraps around the globe horizontally in the middle of the distance between the poles and divides the globe into two parts:

1. Northern half
2. southern half

The equator is at "zero" geographic latitude and serves as a reference for all the climates in the world.

The seasons at the equator

Close to the equator, there is no significant difference between the four seasons, temperatures are high throughout the year except for some periods during the wet season, people can distinguish two seasons in the equatorial region:

1. moist
2. dry

However, most of these areas near the equator are humid throughout the year, and the seasons vary depending on many factors, including altitude and proximity to the oceans.

Geodesy of the equator or geometry of the equator

This line on the Earth is a line on which equal distances are measured, as in surveying to show the difference between degrees of longitude that measures distances to the east and west. The circumference of the Earth on the equator is about 40.076 km, each degree of longitude on the equator is equivalent to 111.32 km.

tropical climate

The climate at the equator varies according to altitude and its distance from water bodies, especially the oceans. In most of the low-lying tropical lands, rains fall heavily and normal temperatures are regulated throughout the year, except for the eastern African coast that only light rain falls on, and the season is dry and lasts for long periods.

temperature

The temperature in the tropical climate is high throughout the year, its average is not less than 27 degrees Celsius, there is no clear difference between the months of the year because the sun does not go far in the equatorial region from the vertical position, the temperature in the tropical climate during the night does not fall below 20 degrees Celsius However, it is considered low for the peoples of the regions in that climate, so it is often said that the night is the winter of the tropical regions.

rain

The main rain at the equator is the solstice, meaning that it results from the convection process that contributes to the heating of the air near the surface, so it rises and its temperature drops to the point of condensation. The air close to the surface causes it to expand and decrease in density, so it rises to the top and loses energy.

At a rate of one degree Celsius in every hundred meters, this is the result of expansion due to the lack of pressure and it gets colder, so its relative humidity rises to the point of saturation and condenses to form cumulus clouds. Same almost every day.

Here are the countries that the equator passes through:

1. Kiribati
2. Ecuador
3. Indonesia
4. Brazil
5. Colombia
6. Uganda
7. Kenya
8. Somalia
9. Maldives
10. Democratic Republic of the Congo
11. Gabon
12. Sao Tome and Principe
13. Republic of the Congo
