| A | B |
|---|
| Convergent Lifting | air flowing from different directions into the same low-pressure area is converging, displacing air upward |
| ITCZ | air mass coming together; equatorial low pressure |
| Convectional LIfting | air mass passes from a maritime source region to a warmer continental region(urban heat island/plowed field) |
| Orographic Lifting | Air is forcibily lifting upslope as it is pushed against a mountain |
| Frontal Lifting | The leading edge of an advancing air mass is its front |
| Unstable | if air keeps rising |
| Stable | air stops rising |
| pressure lowers | temp will drop/cool as |
| cool by expansion | adiabatic cooling |
| Environmental Lapse rate | Varies |
| DAR | 10 degrees celcius per 1000m - constant cooling rate - never changes |
| Any enivronmental lapse rate greater than 10degrees/1000m | produces unstable atmosphere |
| any environmental rate less than 10degrees/1000m | produces stable atmosphere |
| unstable | rising air is less dense than the environment/More than the MAR and DAR |
| stable | Rising air is equal or more dense than the environment/Less than the MAR and DAR |
| Cold Air flowing S & W | as part of the Easterlies air system |
| cyclogenesis | process of forming warm fronts and cold fronts |
| midlatitude cyclone | Cyclogenesis State; Open State; Occluded Stage; Dissolving Stage |
| Cyclogenesis Stage | Formation Begins - warm/cold fronts pushing and shoving |
| Open Stage | Cold Front and Warm Front produce inverted "V" |
| Occluded Stage | A Draw; a mixing of back and forth |
| Dissolving Stage | Cold Air Cuts of Warm air |
| Cold Fronts | Violent colliding - can sometimes create a mega cyclone |
| Lightning | electrical discharge of neg. in one place/pos. in another place as air moves about |
| Thunder | expansion of air/leaves a vaccuum created by the lightning |
