air pressure

• boundary that separates cold polar air from warmer air masses in mid-latitudes.

• the force that transfers molecules from areas of high pressure to areas of low pressure.

• drives winds into and away from the equator on both hemispheres

• The weight of the atmosphere, and the force exerted by molecules in a column of air

Air pressure equasion

• (P=1000mb x .5 (x/5.6)

• y=mx+b

• RH=MR/SMR

• P=10,000mb x (.6 x x/5.6)

Air pressure equasion

• the winds that occur when there is nothign to slow down the PGF.

• shows the relationship between elevation and pressure.

• The force created by water vapor , anything that is less than the full 1%

• forms high in the atmosphere between the Polar cell and the Ferrel cell.

1000mb in this equation

• standard value for pressure on the earth's surface, 100% of the atmosphere is above us.

• is our height/elevation in km

• the force that transfers molecules from areas of high pressure to areas of low pressure.

• is our % above equation, tells us that as we move off the earth's surface, how much of the atmosphere is pushing against us at a set elevation.

" .5 (x/5.6)" in the equation is what

• is our height/elevation in km

• standard value for pressure on the earth's surface, 100% of the atmosphere is above us.

• Always moves from high pressure to low pressure.

• is our % above equation, tells us that as we move off the earth's surface, how much of the atmosphere is pushing against us at a set elevation.

"X" in our equasion

• Our location in decimal form

• The force created by water vapor , anything that is less than the full 1%

• is our height/elevation in km

• The force exerted by saturated air and only exists when we use a full 1%

Vapor Pressure:

• is our % above equation, tells us that as we move off the earth's surface, how much of the atmosphere is pushing against us at a set elevation.

• is our height/elevation in km

• standard value for pressure on the earth's surface, 100% of the atmosphere is above us.

• The force created by water vapor , anything that is less than the full 1%

Pressure Gradiance force(PGF)

• the force that transfers molecules from areas of high pressure to areas of low pressure.

• The force exerted by saturated air and only exists when we use a full 1%

• The force created by water vapor , anything that is less than the full 1%

• is our height/elevation in km

"What does the 3-cell model tell us about where cold air+ warm air is? And how do move this (cold and warm) air together?"

Answer explanation

It tells us that, The only force strong enough to create wind across the earth's surface is low pressure. We use the low pressure in the model and create a "blender" that's going to combine cold and warm air = a storm.
