武夷山脉
The Wuyi Mountains act as a protective barrier against the inflow of cold air from the northwest and retain warm moist air originating from the sea. As a result, the area has a humid climate (humidity 80 to 85%) with high rainfall (annual average 2,200 millimeters in the south-west and 3,200 millimeters in the north) and common fogs. Lower altitudes experience annual temperatures in the range from 12 °C to 18 °C.
