Why is the summer solstice hotter than the winter solstice?

At this time, the direct sunlight reaches its maximum in the northern hemisphere, while it reaches its maximum in the northern hemisphere on the solstice in winter, so the temperature from summer to the sun is higher than that from winter to the sun.

From winter to around, although the northern hemisphere has the shortest sunshine time and receives the least amount of solar radiation, the accumulated heat on the ground in summer can also provide some supplement, so the temperature is not the lowest at this time. "After eating the winter solstice dinner, the days get longer." After the winter solstice, the days get longer and longer.

However, the solar radiation obtained on the ground is still less than the heat lost by the ground radiation, so the temperature will continue to drop in the short term. In China, except for a few islands and coastal areas, 1 is the coldest month, so there is a folk saying that winter solstice is not too cold, and astronomy also stipulates that winter solstice is the beginning of winter in the northern hemisphere.
