Cold air often brought about rain and other weather changes. Rainfall varies in different areas when affected by cold air. In the northern region, cold air will cause rainfall in Inner Mongolia, Northeast China, Northwest China and other places. For example, there may be light rain and moderate rain in some places in Hei Long River; there may be light rain in most parts of Ji Lin, eastern Liaoning and northern Inner Mongolia; light rain is mainly in Northwest China; there may also be light rain accompanied by strong winds of magnitude 4 - 5 in eastern Shandong. Moreover, the cold air would cause severe cooling in the central and eastern parts of Inner Mongolia, forming a frost line and accompanied by strong winds. In the south, there was more rainfall in the southwest under the influence of cold air. For example, there was light rain in Sichuan, Chongqing, western Guizhou and most of Yunnan, moderate to heavy rain in southern Sichuan and northern Yunnan, moderate to heavy rain in southern Yunnan, and light rain in most parts of Fujian and eastern Guangdong. The intensity, range, and duration of rainfall under the influence of cold air were affected by many factors, including air humidity, geographical location, topography, and so on. Cold air was mostly formed in the polar regions and the Siberian continent. When the cold air went south, it met with the warm and humid air. As the warm and humid air rose, the water vapor cooled and condensed, forming rain. "Luo Han's Lyric Collection" is equally exciting. Everyone is welcome to click and read it!
