Sun Leng, senior engineer of the Climate Monitoring Office of the National Climate Center, explained in an interview with the China Meteorological News: Generally speaking, whether extreme cold weather can occur in a region is affected by the latitude. Extremely cold weather is generally only possible in high latitude areas. But if you analyze the data carefully, some careful people may find that Tibet and Qinghai have lower latitudes than Gansu.

However, these two areas have experienced extremely cold weather, while Gansu has not experienced extreme cold weather. In this regard, Sun Leng explained that the occurrence of extremely cold weather is also affected by factors such as the location of sea and land, ocean currents, topography, topography, altitude, properties of the underlying surface, season, weather conditions and human activities.
