Distribution and characteristics of climate types in China

In winter, the temperature between the north and the South varies greatly. The 0 ℃ isotherm in January is distributed along the Qinling Huaihe line. To the south of this line, the average temperature in January is above 0 ℃, to the north of this line, the average temperature in January is below 0 ℃
