Why in winter the middle and higher latitudes receive less radiation than in summer and tilt of the Earth axis on its orbital plane around the sun causes?
Slanting sun rays, they travel a long distance in the atmosphere and cover large areas on the surface; hence less insolation per unit area is received in higher latitudes. Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere.

Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere and when the South Pole tilts toward the Sun, its winter in the Northern Hemisphere. The earth's axis of rotation is tilted 66.5 degrees with respect to its orbital plane around the sun and its axis of rotation is inclined 23.5 degrees from the perpendicular, with respect to this plane. The tilt of the Earth is what causes seasons to occur. These are the seasons in relation to the Northern Hemisphere. The tilt also produces effects such as the Midnight Sun, where the Sun never sets during some summer nights in very high-latitude regions. Earth's axis is tilted away from the Sun at the December solstice and toward the Sun at the June solstice, spreading more and less light on each hemisphere. At the equinoxes, the tilt is at a right angle to the Sun and the light is spread evenly. At higher latitudes, the angle of solar radiation is smaller, causing energy to be spread over a larger area of the surface and cooler temperatures. In contrast, those in higher latitudes receive sunlight that is spread over a larger area and that has taken a longer path through the atmosphere. As a result, these higher latitudes receive less solar energy. The farther north or south you are from the Equator, the more radiation you will receive. This is a result of the Earth's magnetic field deflecting some of the cosmic radiation away from the equator and toward the North and South poles. The Earth revolves around the sun in an elliptical orbit and is closer to the sun during part of the year. When the sun is nearer the Earth, the Earth's surface receives a little more solar energy. The Earth is nearer the sun when it is summer in the southern hemisphere and winter in the northern hemisphere.
Due to slanting sun rays, they travel a long distance in the atmosphere and cover large areas on the surface, hence less insolation per unit area is received in higher latitudes
