This is the second "snow typhoon" in Northeast China this year and the third national cold wave in China since October. According to perennial data, the average number of cold waves in China from September to November is 1.9, and more in the early years, less than 1.5 since the new century. There is no doubt that before the arrival of winter in the sense of climate, the cold wave in China has greatly exceeded the standard.
