Which solar term has the longest day in the northern hemisphere?

The longest day in the northern hemisphere is the summer solstice. Solstice is the earliest of the 24 solar terms. When the summer solstice comes, the temperature rises gradually. On that day, the sun moved to 90 degrees of the yellow meridian, and the position of the sun directly on the ground reached the northernmost point of the year, almost directly on the tropic of cancer. On this day, the sunshine time in the northern hemisphere is the longest, so the summer solstice is the longest day in the northern hemisphere.

The summer solstice is in midsummer, that is, at noon, belonging to the sun; Although summer is full of yang and the daytime is the longest, it is not necessarily the hottest day of the year, so the heat near the surface is still accumulating and has not reached the maximum.

After the summer solstice, the ground is heated strongly and the air convection is strong, which is easy to form thunderstorms. The summer solstice is not only one of the 24 solar terms, but also a festival in the ancient "four seasons and eight festivals". Since ancient times, people have had the custom of offering sacrifices to their ancestors in the summer solstice. In addition, after the summer solstice, people generally drink Qingbuliang soup, herbal tea and sour plum soup to escape the heat.

From summer to the sun, the direct position of the sun on the ground reaches the northernmost point of the year, almost directly to the Tropic of Cancer, and the daytime in the area north of the Tropic of Cancer in the northern hemisphere reaches the longest, and the farther north it is, the longer it is.
