Afganets

a local southwesterly wind which blows in the upper reaches of the Amu Darya. It arises because of the aerodynamic acceleration of the warm air mass which flows from the southwest and which is compressed between the spurs of the Gissar Range, on one side, and the cold front approaching from the northwest, on the other. The velocity of the afganets is 17–25 m per sec. The afganets carries much dust and greatly lowers the relative humidity of the air, which has a harmful effect upon vegetation. In Termez the afganets blows from 40 to 70 days a year.
