Medium-height mountain sub-area - from 1000 to 2000 m
• High-mountain sub-area
- above 2000 m
The varying relief forms influence the
temperature regime and the air humidity, the wind velocity and the amounts
The average wind velocity in the town's region
is about 0.8 m/sec, and the hollow character of the area predetermines the
very great number of windless days, which constitute averagely 72 % of the
days in a year.
