[Explanation] There is a saying in China that "counts nine cold winters". From the winter solstice, count "nine" to calculate the season. Every nine days is one "nine".
The proverb says "The cold is on March 9th, and the heat is on the middle". The coldest time of the year is on "March 9th".

Although the solar radiation began to increase after the winter solstice, for a long period of time, the ground heat income was still far less than the expenditure, so the temperature was still falling. About 18 days later, the ground heat budget was close to equilibrium, and it entered the lowest temperature. The time period "March Nine".
[Explanation] In the past "Twenty Nine", Heilongjiang has already reached a new level of cold. The temperature in many parts of the Greater Xing'an Mountains exceeded minus 40℃, and the "coldest town in China" Huzhong experienced extreme cold of minus 40℃ for many consecutive days. the weather.
However, with the advent of the "March 9", the temperature in various parts of Heilongjiang has begun to warm up. Many citizens said that this year's "March 9" was even lower than the "2 9".

During the “Twenty-Nine” period, Heilongjiang Province was affected by the cold polar air, and the average temperature was lower than that of the same period in history. The western region was 1～3℃ lower, and the central and eastern regions were 4-6℃ lower. Therefore, in the past The "Twenty Nine" is very cold.
So in the first 4 days of the "March 9", our province was affected by the warm air, and the temperature continued to rise. In the last few days, there has been an alternating activity of cold and warm air. Generally speaking, the "March 9" is warmer than the "2 9".
[Explanation] According to the Heilongjiang Meteorological Observatory, there will be heavy snow in the south of Mudanjiang on the 15th, and moderate snow in the east of Harbin, Jixi, and north of Mudanjiang. The roads are smooth due to the snowfall. Snow may affect traffic in areas with heavy snowfall.
Experts reminded that the temperature drops after the snowfall, and citizens need to add clothes to keep warm when traveling.

We predict that the average temperature of the entire "March 9th" will be about 2℃ higher than that of the "March 9th", but this does not mean that this year's "March 9th" is not cold, because this year's "March 9th" is still It was about 1°C lower, and the cold continued. This "three nines" is still very cold.
