The region where we do not find air is space.
A low pressure region should mean that the region is low in air. The air from the surrounding region (which is comparatively at higher pressure) moves into this low pressure region creating a wind. So, wind is the movement of air from a high pressure region into a low pressure region. Warm air is lighter than cold air. Warm air being lighter moves upward creating a low pressure region. So, wind could also be a movement of air from cooler to warmer region.
An airshed is the air supply of an individual region, or the region supplied by a source of air.
Air Mass or equlibrium
When air pressure is constant throughout a region of the atmosphere the region is in a state is called equilibrium.
An air shed is the air supply of a specific region.
A low pressure region should mean that the region is low in air. The air from the surrounding region (which is comparatively at higher pressure) moves into this low pressure region creating a wind. So, wind is the movement of air from a high pressure region into a low pressure region. Warm air is lighter than cold air. Warm air being lighter moves upward creating a low pressure region. So, wind could also be a movement of air from cooler to warmer region.

A humid region is a region where humidity (moisture in the air) is greater than 50%.
yes it does, it takes on the characteristics of its region.
it is cold air
