Which light climate zone does Qingdao belong to?

In winter (12 ~ February), the temperate monsoon climate is basically controlled by the westerly airflow over China. Along the south side of the Qinghai-Tibet Plateau, across the eastern coast of China to Japan, it is a stable southern branch of westerly jet, and it is a northern branch of westerly jet over northern Xinjiang, Inner Mongolia and North China. This jet is related to the polar front. The main weather system affecting Shandong in winter is cold front, which is the interface between polar continental air mass and denatured polar continental air mass. After the strong cold front crosses the border, northerly winds often appear and cause strong cooling. There will be rain and snow when the warm and humid air current is strong in the south, and sometimes it will rain. When a deep trough moves out of the Qinghai-Tibet Plateau and the southwest airflow is strong, the southern cyclone will also affect Shandong northward, resulting in windy, rainy and snowy weather. In winter, the strong, dry and cold Mongolian high pressure controls our country and dominates the activity of cold air. Shandong is located in the southeast of Mongolia cold high, with northerly winds prevailing.
