Because over a long period of time, the sun appears to wiggle back and forth, north and south, between the Tropic of Cancer (23 degrees north latitude) and the Tropic of Capricorn (23 degrees south latitude), making a complete wiggle in one year. In the course of that process, it crosses the equator twice, and when it does, the equator experiences maximum solar radiation. Actually, when you think about it, EVERY spot on Earth that's anywhere between the Tropics of Cancer and Capricorn receives two peaks of solar radiation during a year.
Solar maximum can occur up to 42 degrees north of the equator as it did in 1859.
Short periods of climate change caused by changes in the amount of solar radiation an area receives are known as solar forcing. This can lead to variations in Earth's climate, such as ice ages or interglacial periods. Changes in solar radiation can impact temperature and weather patterns on a regional or global scale.
Equator has a lower angular deflection of sunlight and therefore warmer temperatures
In June, the outer edge of the atmosphere at the equator receives less solar radiation than the north pole and 40 degrees north latitude because the angle of incidence of the sun's rays is lower at the equator due to the Earth's axial tilt. This results in the solar radiation being spread over a larger area at the equator compared to the more concentrated radiation received at higher latitudes.
The belt of maximum solar energy input to Earth is the Equator. This is because the Sun's rays hit the Earth more directly at the Equator, resulting in more intense solar radiation compared to other latitudes.

The equatorial regions near the equator receive the most solar radiation because the sun's rays are more direct at these latitudes, resulting in higher levels of solar energy. Zones around the equator experience consistent high levels of solar radiation throughout the year due to their proximity to the sun's path.

This can lead to variations in Earth's climate, such as ice ages or interglacial periods. Changes in solar radiation can impact temperature and weather patterns on a regional or global scale.
In January, the region near the equator typically has the highest amount of absorbed solar radiation due to the more direct angle of the sun's rays. This region receives more direct sunlight, leading to greater absorption of solar radiation compared to regions farther from the equator.
Equator has a lower angular deflection of sunlight and therefore warmer temperatures
Regions away from the equator receive less solar radiation because the angle at which the sunlight strikes the Earth's surface is more oblique, spreading the energy over a larger area. This reduces the intensity of solar radiation received compared to the more direct and concentrated sunlight at the equator.
Solar radiation is most intense around noon when the sun is directly overhead. This is because the sunlight has the shortest path through the Earth's atmosphere, resulting in maximum intensity.
The sun's incoming solar radiation is strongest at the equator because it falls directly overhead. At the poles, the angle is more oblique, resulting in weaker solar radiation.

Solar radiation has a greater impact on climate at the equator compared to polar regions. This is because the equator receives more direct sunlight throughout the year, leading to warmer temperatures. In contrast, at polar regions, sunlight is spread out over a larger area, resulting in cooler temperatures.
