What kind of weather will the continental air mass bring to the surrounding area after it passes through the ice lake? Please elaborate.

Continental air mass: Air mass produced in Chinese mainland. It can be divided into tropical continental air mass and polar continental air mass because of different latitudes.

The continental air mass is hot in summer, dry and cold in winter and stable in stratification. Arctic continental air mass (cA) is formed in the ice-covered Arctic Ocean. It is characterized by low temperature, strong inversion layer, stable gas layer and low humidity. So its weather is dry, cold and sunny. Continental polar air masses are formed in middle and high latitudes, such as Siberia, Mongolia and Canada. In winter, the temperature of the lower air mass is very low, the inversion phenomenon is strong, the air layer is stable, and the weather is similar to the ice ocean air mass; In summer, affected by the thermal conditions in mainland China, the air layer is unstable, and with the increase of humidity, cloudy weather often occurs.
