On the winter solstice, the position where the sun shines directly on the ground reaches the southernmost end of the year, almost directly on the Tropic of cancer (23 ° 26's). On this day, the northern hemisphere gets the least sunshine, 50% less than the southern hemisphere. The northern hemisphere has the shortest day, and the farther north, the shorter the day. I sorted out why the winter solstice is not the coldest time_ Why is the winter solstice not the coldest? I hope it can help you.
Why is the winter solstice not the coldest time
The winter solstice is not the coldest time of the year, just as the hottest time of the day is not 12 o'clock, and the darkest time is not 12 o'clock at night. Although the light is the least on the day of the winter solstice, it needs a process to freeze into a cold day.
No.
On the winter solstice, the northern hemisphere has the lowest solar height and the shortest day time, but the temperature on the winter solstice is not the lowest.
This is because when the direct point of the sun moves to the southern hemisphere, the temperature in the northern hemisphere begins to decrease a little. The cooling in the northern hemisphere is a continuous and slow process. On the winter solstice, when the sun shines directly on the Tropic of cancer, the earth's temperature is still decreasing with that downward trend (it seems that there is inertia, which is related to the transmission of heat energy)... After the winter solstice, the direct point moves north to a certain extent, The temperature in the northern hemisphere will rise slowly. Similarly, when the sun shines directly on the northern hemisphere, it is not the hottest, and it is the hottest at 2:00 noon instead of 12:00.)
At the beginning of the winter solstice, i.e. the beginning of counting nine, the so-called "no action in 1929, no action in 3949", the coldest time of the year is 399 and 499. This year's Spring Festival is January 25, 2020, which is the eighth day of 49th day. The days before and after the year are also the coldest time of the year. Please keep warm.
