SSC MTS EXAM

Detailed explanation-1: -As the heated air rises, it expands, which is measured at the surface as low air pressure. Expanding air cools, which forces it to lose its moisture as rain or snow. The opposite is true for sinking air. Such air compresses and warms.

Detailed explanation-2: -As the air continues to descend towards sea level, atmospheric pressure increases which causes a temperature increase. Because of all of this (scientifically called adiabatic warming), the leeward side is generally warmer and drier.

Detailed explanation-3: -Sinking air increases pressure at surface, and ascent decreases pressure at surface. 5. In addition air pressure changes caused by variations of temperature and water vapor content, air pressure can also be influenced by the circulation pattern of air.
