The coldest reason in 3949

There is a folk saying that "1929 can walk on the ice in 3949", which means that the temperature will not be very low in the early stage. After 3949, the temperature will drop and the river will start to freeze. You can walk on the ice to express the cold degree of the weather.

From winter to March 9, the average daily increase is only about one minute, and the direct angle between the sun and the ground increases slowly. The daily heat budget of the ground is still in a deficit state, so it continues to lose heat and the ground temperature continues to drop.

Only during April 9th, the total heat budget deficit on the ground reached the maximum, and because the temperature was mainly affected by the ground temperature, the temperature was the lowest during March 9th and April 9th.

In addition, around March 9, the cold air mass in Siberia also developed to a very strong stage, and the frequent invasion of strong cold air is also one of the reasons for the low temperature.
