Is the winter solstice the coldest time of the year? When is the coldest?
For many years, we have habitually thought that the winter solstice is the coldest time of the year, but it is not. Why? Let’s find out together. In the eleventh month of the lunar calendar, the north wind was biting and the cold current was rolling, brewing a heavy snow. Shuimoxiansheng.com presents you with wonderful content for November 2018 of the lunar calendar.Why isn’t the winter solstice the coldest time of the year?In fact, the winter solstice is the same as the summer, and the hottest day is not the summer solstice. To explain, we can regard the earth as a large temperature storage device. When the sun shines more, it absorbs heat, and when the sun shines less, it releases heat. That is why it is very hot even when there is no sunlight in the summer nights, because the earth releases the heat absorbed during the day. But in winter, the situation is the opposite. The earth releases too much heat and is in a state of absorbing heat. Therefore, it will not be very hot even if there is sunlight during the day. There is also a more official statement that the change in sunshine is not linear, but follows the law of the "sinusoidal" curve. The change in sunshine on Earth at the winter solstice is "zero", and the change in sunshine approaching or leaving the winter solstice is very small (the top of the sine curve), while heat dissipation continues almost unchanged, and the weather will become colder and colder. It was not until early February that the weather began to warm up noticeably due to the rapid increase in sunshine (steepening of the sine curve). Therefore, the coldest time of the year is the 39th day of the winter solstice. The winter solstice can only represent the day with the shortest daylight in the year, just like the summer solstice. The hottest time in summer is not at the summer solstice, but more than half a month after the summer solstice. The summer solstice can only represent the day with the longest daylight in the year. |
