|
|
|
Temperature change due to change in pressure
|
adiabatic temperature change
|
|
|
When air is forced up (cool air which would not rise except it's being shoved up or over a mountain)
|
forced lifting
|
|
|
When warm air flows over a cold surface and cools to dew point, then forms clouds
|
advective cooling
|
|
|
layered, usually low-altitude, forms by advective cooling. "Overcast clouds", little rain
|
Stratus
|
|
|
heaped/piled, mid-altitude, forms by convective cooling, fair-weather clouds

|
curly, high-altitude, wispy, made from icy crystals
|
Cirrus
