What receives the least solar radiation and has the coldest climate and what receives the most solar radiation besides the equator?
Dear Rk Naresh,
This question is the reverse of the question you mentioned here above.
Hence, the region of the Earth that receives the least solar radiation and has the coldest climate is typically found in the polar regions, specifically the North and South Poles. These areas experience extremely cold temperatures and receive very little solar radiation, especially during their respective winter seasons when they are tilted away from the Sun. The polar regions can have months of darkness and very limited sunlight during their respective winters, contributing to their extreme cold.
Conversely, the region that receives the most solar radiation, aside from the equator, is typically found in the subtropical zones known as the Tropics of Cancer and Capricorn. These are the regions located at approximately 23.5 degrees north and 23.5 degrees south of the equator, respectively.
Humble regards,
The Polar Regions receive the least solar radiation. On an average those would be the poles. As you correctly pointed out, due to the tilt of the Earth's axis, there are large areas that receive very little and sometimes no sunlight at all and those change throughout the year. But on an average, poles are the ones that get the least amount of solar radiation.Polar climates have year-round cold temperatures, with the warmest month less than 50°F (10°C). Polar climates are found on the northern coastal areas of North America, Europe, Asia, and on the land masses of Greenland and Antarctica. Latitude, climate, and weather patterns are major factors that affect insolation—the amount of solar radiation received on a given surface area during a specific amount of time. Locations in lower latitudes and in arid climates generally receive higher amounts of insolation than other locations. The Equator receives less insolation than the tropics because of the presence of clouds. At the same latitudes the insolation is more over the continent than oceans because clouds over the ocean reflect back the sunlight. The equator receives the most direct and concentrated amount of sunlight. So the amount of direct sunlight decreases as you travel north or south from the equator. Look at the diagram of Earth above that shows different latitudes. Because the Earth is a sphere, the surface gets much more intense sunlight (heat) at the equator than at the poles. During the equinox (the time of year when the amount of daylight and nighttime are approximately equal), the Sun passes directly overhead at noon on the equator. The amount of solar energy received at the North Pole is 30% higher during the summer solstice than the amount of solar energy received at the Equator. Clouds do most of the reflecting in these NASA images. The equator receives the most direct and concentrated amount of sunlight. So the amount of direct sunlight decreases as you travel north or south from the equator. Look at the diagram of Earth above that shows different latitudes.
