| them. The high peaks block off
the warm and moisture air current. Therefore vehement convection occurs
when the warm and moisture air rising along the slope meets the cold air,
and then produces the cloud and rain. The mountain has an annual precipitation
of 2,395mm and 183 precipitation days and annual frost-free period of 258
days. The enormous relative height leads to rain at the bottom of the mountain
and snow at the top of the mountain. The annual snow days is 49.1 days on
average, varying from 85 days to 28 days. The frequency of west-south wind
blows more frequently than west-north wind. |
