Question

The wind which descends on the leeward side is heated adiabatically and is called____
A) loo
B) Trade wind
C) Katabatic wind
D) Monsoon

Answer 1

Hint:The windward side of an island faces the prevailing winds, or trade, while the leeward side of the island faces away from the wind, shielded by hills and mountains from prevailing winds.

The windward side is subjected to prevailing winds that contain ample moisture and in striking the surrounding mountains and hills that serve as a barrier to them, they shed their moisture containing in that pain That is why more rainfall is obtained from the windward side.

Complete answer:
Katabatic wind is the general term for downslope winds rushing to the valleys or planes below from high elevations of mountains, plateaus, and hills down their slopes. Katabatic winds occur in many parts of the world and, depending on where they are located and how they are shaped, there are many different names for katabatic winds.

At the lee side of a mountain range situated in the direction of a depression, warm dry katabatic winds occur. The Foehn winds are examples of these descending, adiabatically heated katabatic winds.
The downslope gravity flow of cold, dense air results in cold and generally dry, katabatic winds, such as the Bora. The landscape will flow and reinforce katabatic flows slumping down from uplands or mountains and are then referred to as mountain gap winds such as the Santa Ana, mountain breeze or drainage wind.

Frost hollows are formed by the gentler katabatic flows of hill slopes. Mountain breezes are part of a wind pattern that is local. The mountain breeze will break down, reverse and blow upward when the mountainside is heated by the Sun. These winds are known as the anabatic wind or valley wind.

Hence the correct answer is option ‘C’.

Note: An adiabatic process is defined as a process in which there is no heat transfer. This does not indicate that the temperature is constant, but rather that no heat is transmitted into or out of the system. As the strain on an adiabatically isolated system is reduced, adiabatic cooling occurs, allowing it to expand, enabling it to operate on its surroundings.
