GEOG 2050 : Test 2 2
Document Summary
Pressure exerted by water vapor: a measure of the actual vapor content (how much water is in the air, saturation vap. Cool the air temp, like at night what happens to rh: 3. Cool the air more, to point where air is cool it reaches saturation (dew point temperature: 4. What happens if we cool the air further: condensation or deposition will occur, dew or frost, energy is released to surrounding environment. Small increase after daylight because the dew or frost from the night before is evaporating as soon as the sun comes up. Stable conditions: if air is forced to rise, it will sink back to its original position after the lifting is removed: at surface, implies high pressure and clear conditions, implications for pollution dispersion. Unstable conditions: if air is forced to rise, it will continue to rise, even after the lifting force is removed: when air rises it cools, condenses, and maybe causes precipitation.
