| 2 Ways air cools | Winds Lift Air Up; Adiabatic heating/cooling |
| DAR | Dry Adiabatic Rate |
| MAR | Moist Adiabatic Rate |
| Adiabatic Change | Change in Temperature due ONLY to a change in pressure |
| fog | ground cloud |
| 3 types of Fog | Advection; Evaporation Fog; Radiation Fog |
| Advection Fog | Warm air moving over cooler ground |
| Evaporation Fog | Cold air moving over warm ground |
| Radiation Fog | Rapid Temp Drop - clear night Heat radiates back to atmosphere |
| 2 Critera of Clouds | Altitude and shape |
| Cloud Altitude | Low (Below 2000m); Middle (2000-6000m); High (Above 60000m) |
| Cloud Shapes | Stratus; Cumulus; Cirrus |
| Cumulonimbus | clouds with vertical development |
| Stratus | layered clouds |
| Cumulus | Puffy clouds like cotton balls |
| Cirrus | Wispy clouds (usually ice crystals) |
| Production of Rain | Temp decrease to Dew Point; RH-100%; Condensation; Clouds; Collision-Coalescence; Heavy Drops of Water; Rain |
| Rain | When water molecules accumulate and weigh more than atmosphere |
| as temp clouds drop | speed will drop |
| cloud temperature | heat energy determines how fast they collide and stick together |
| Dew Point | Temperature at which relative humidity reaches 100%. |
| How high can R.H. go | 100% |
| SATURATION | CANNOT HOLD ANY MORE MOISURE AND THE MOISTURE CONDENSES BACK TO A LIQUID STATE |
| clouds develop because | water has been squeezed out of the air. |
| Relative Humidity goes up | when air temperature gets colder |
| Relative Humidity goes down | when air temperature gets warmer |
| relational humidity | = relative humidity |
| humidity | % of water vapor in the air |
| relative humidity | maximum amount of water vapor the air can hold |
| Unique Properties of Water | 3 Phases; Heat in/out; Cohesion; Solvent |
| 3 Phases of water | solid-ice; liquid-water; gas-water vapor (steam) |
| Boiling point of water | 100 degrees celcius |
| Cohesion | polarity of water produces a hydrogen bond |
| Solvent | water dissolves most materials |
| sublimation | (+ or -) solid to gas or gas to solid |
