Extended data:
A, the number nine calculation method:
1, starting from the winter solstice, the first nine days are called "September 19th"; The second 9 days is called "29", and so on, counting to "99" and 8 1 day.
2. In order to calculate the number nine, Want Want often starts from the solstice in winter, that is to say, this day from the solstice in winter is called "Fujiu", and every nine days is "Fujiu", and so on.
Second, the principle of 99 folk songs:
1. During the winter solstice, the daytime is the shortest, the angle of direct sunlight on the ground is the smallest, and the ground gets the least solar heat every day. After the winter solstice, the daily heat budget of the ground is still in deficit, so the heat is continuously lost and the ground temperature continues to drop. The deficit of ground total heat balance reached its maximum on April 9, resulting in the lowest temperature on March 9 and April 9.
2. In addition, the cold air mass in Siberia also developed to a very strong stage around March 9, and the frequent invasion of strong cold air is also one of the reasons for the low temperature.
