What kind of monsoon climate is Xi 'an, and what direction does it often blow? Where is the upper air inlet? I mentioned it in high school geography when I was at school, but I forgot it later.

Xi belongs to temperate monsoon climate.

Influenced by polar ocean air mass or denatured tropical ocean air mass in summer, the southeast wind and southeast wind prevailing in winter are usually northwest wind.

The headwind refers to the direction of prevailing wind, and the frequency of prevailing wind in different directions is different in different seasons and different time periods.
