Causes of heavy snowfall in Yanji

Topographic factors and climatic conditions.

1. Topographic factors: Yanji is located in the hilly area of Changbai Mountain, with high altitude and large terrain. This terrain is easy to form mountainous areas and low-lying areas, thus affecting the distribution of temperature and snowfall. The temperature is usually low in high altitude areas, which is easy to form snowfall.

2. Climatic conditions: Yanji is located in the mid-latitude area, close to the southward path of Siberian cold air, and is often affected by cold air. In winter, Siberian cold air meets the warm and humid airflow in the south, which is easy to form precipitation, including snowfall.
