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

The winter solstice solar term is the solar term with the shortest day and the longest night in the northern hemisphere, so the winter solstice is also called "short day" or "long night".

The winter solstice is the 22nd of the 24 solar terms. In winter solstice, the direct sunlight point has moved southward to the tropic of Capricorn across Australia, that is, the direct sunlight point in winter solstice is farthest from the northern hemisphere, with the smallest oblique angle with the northern hemisphere, and the northern hemisphere has the shortest sunshine exposure time, so the northern hemisphere has the shortest daytime time and the longest night time.

Characteristics of winter solstice

1, short sunshine time: Although the northern hemisphere has the shortest sunshine time and receives the least amount of solar radiation, the accumulated heat on the ground in the summer half year 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.

2. Low temperature and cold climate: From the climate point of view, the average temperature in the northwest plateau is generally below 0℃ during the winter solstice, and the southern region is only about 6℃ to 8℃.
