Astronomically speaking, is the winter of solstice perihelion or apohelion? Give the most intuitive natural phenomena as reasons!

At perihelion, the distance between the sun and the earth is 1.4438+0 billion kilometers; At apohelion, the distance between the sun and the earth is 1.52 1 100 million kilometers. The difference between them is about 5 million kilometers, which is very small compared with the distance between the sun and the earth. Moreover, for the southern hemisphere, the perihelion is winter and the perihelion is summer, so this is not the reason for the temperature difference between the four seasons. The temperature of the four seasons depends on the angle and time of the sun, which is for us, that is, for people in the middle latitudes of the northern hemisphere. The size of the irradiation angle determines how much heat the earth receives, thus causing the temperature. In addition, around the summer solstice, the sun rises in the northeast and sets in the northwest, and the sun stays above the horizon for a long time. This situation of long days and short nights makes the ground in long-term light, which further aggravates the rise of ground temperature; On the contrary, around the "winter solstice", the sun rises in the southeast and sets in the southwest, and the sun stays above the horizon for a short time. This situation of short days and long nights further aggravated the cooling of the ground. So it is hot in summer and cold in winter. Around the vernal equinox and autumnal equinox, the angle of sunlight is between the above two situations. The sun rises near due east and sets near due west. The length of day and night is almost the same, and it is also between the summer solstice and the winter solstice, so the spring and autumn seasons are formed.
