Core Points - The snowfall in Beijing is characterized by large snowflakes and significant accumulation in the western mountainous areas [1] - The snowfall is attributed to the influence of an easterly wind return weather pattern, which enhances precipitation in the region [1] Weather Conditions - The snowfall is a typical return snowfall for the North China region, relying on easterly winds [1] - The geographical features of Beijing's western mountains trap the easterly winds and moisture, leading to increased snowfall in these areas [1] Snowflake Formation - The temperature of the cloud layer during the snowfall ranges from -10°C to -20°C, which is conducive to the rapid growth of snowflakes [1] - The collision and adhesion of snowflakes during their descent result in the formation of large, fluffy snowflakes, creating a "feather-like snow" visual effect [1] - The structure of the snowflakes is airy, contributing to a greater perceived depth of accumulated snow [1]
