Which side is the windward slope of Taihang Mountain?

The west of Taihang Mountain is windward slope, which means that it is winter, and the northwest wind blows, and the west foot of Taihang Mountain is windward slope. On the contrary, when the southeast wind blows in summer, it is the eastern foot of Taihang Mountain that faces the wind.

Reasons for the remarkable foehn effect on the east side of Shijiazhuang;

The south-central part of Hebei Province is at the foot of Taihang Mountain, which is the leeward side of the turning point of the mountain range from northeast to southwest to north and south. This special terrain causes the perennial temperature in central and southern Hebei Province to be generally higher than that in neighboring provinces and cities. In meteorology, we call this phenomenon "foehn effect". The "foehn effect" is due to the fact that when humid air rises on the windward hillside, water vapor condenses into clouds and rain, and when it reaches the top of the mountain, the air becomes drier and warmer, and then it becomes drier and hotter. This dry and hot air flow is the foehn. Shijiazhuang, located at the eastern foot of Taihang Mountain, has an altitude difference of 1 1,000 m or more. When the foehn airflow descends over Taihang Mountain, the foehn effect often appears in Shijiazhuang area, and the daily average temperature is about 10℃ higher than normal, and sometimes it is more than 10℃ higher than that in southeast cities and counties far away from the foothills (areas without foehn effect).
