Why does air sink down in the atmosphere?
Air under high pressure at midlevels of the atmosphere weighs more than the air below it, so this air in the mid- and upper-levels of the atmosphere sinks. Air sinking down compresses air at the surface, raising temperatures near the ground.
Why does sinking air lead to sunny days?
Also, where the air is sinking it prevents moist, warm air at the surface from rising, where it would eventually cool and form clouds. Sinking air is the primary reason why high pressure leads to sunny days.
Why does sinking air lead to high pressure?
Air sinking down compresses air at the surface, raising temperatures near the ground. Also, where the air is sinking it prevents moist, warm air at the surface from rising, where it would eventually cool and form clouds. Sinking air is the primary reason why high pressure leads…
What makes the atmosphere unstable during a tropical cyclone?
By cooling of the air aloft and Warming of the surface air Cooling of the air aloft – Cold air moving is aloft • this often occurs when an extra tropical cyclone passes overhead – Clouds or air emitting IR radiation to space Warming of the surface air – Surface Heating – suggests that the atmosphere will be most unstable.

What is the difference between stable and unstable air?
•Stable air (parcel)- vertical motion is inhibited – if clouds form, they will be shallow, layered clouds like stratus •Cloud Development – unstable environment –Unstable air (parcel) – vertical motion occurs – commonly produces cumulus, cumulonimbus clouds • A ball in water: – When does it rise? – When does it sink? • An air parcel:
What does high pressure do to the weather?
high pressure-generally brings clear skies and calm air or gentle breezes because air is sinking toward the earth. front-where two air masses meet warm front-The boundary between cool and warm air masses, moving so that the warmer air replaces the cooler
What are the processes that destabilize the atmosphere?
Processes that destabilize the atmosphere 1. By cooling of the air aloft and Warming of the surface air Cooling of the air aloft – Cold air moving is aloft • this often occurs when an extra tropical cyclone passes overhead – Clouds or air emitting IR radiation to space Warming of the surface air
