Question

difference between anabatic wind and katabatic wind

Answer 1

Katabatic is a local wind caused (often at night) by the flow of air, cooled by radiation, down mountain slopes and valleys. It is also caused by the flow of cold air down the slopes of ice caps, such as Antarctica and Greenland. It is caused by ground surface cooling as a result of radiation, which in turn cools the lower air layers. With the rapid loss of heat by radiation, the mountain or ice-cap becomes cold, and the chilled air moves downward under the action of gravity.

Anabatic is an upslope wind formed when air on hill sides is heated by insolation conduction to a greater extent than air at the same horizontallevel but vertically above the valley floor. This cause convectioanl rising of the heated air, which is replaced by cooler air form the valley  floor
