Document Summary

Part 2: when you are above the atmosphere, this means the sunlight isn"t as filtered through, higher radiation. Infrared is absorbed by greenhouse gases: around mid day the radiation is so intense at that time, the surface temperature is above 60 degrees celsius where the air temperature is 17. Major change in temperature within a meter: find that plants are adapted to staying low to the surface. The absorption vs the loss of energy gives the warm daytime and cold night: cold air drainage : drives night-time down-slope "mountain winds, often results in a stable "inversion layer" where colder air is situation below warmer air. If there is moisture there is then a pooling of cold air drainage filling the valley (clouds: the presence of a glacier complicates things: its cold surface generates a dense "katabatic" wind that flows down slope. Warms up as it flows downward: chinook winds : air parcel after descent is warmed due to compression heating.
