Most of weath occurs
Tropo
19% of earth’s gases are here. Ozone
Strat
Meteorites burn up here
Meso
Hottest layer bc
High energy waves absorbed from sun, thermos
Molecules from atmos escape

Know DMT by
Max + min tempt of 24 hrs / 2
DTR formula
Max - min tempt
Sum of daily means / number of days in months
Monthly mean tempt
Average of 12 monthly tempts
Annual mean tempt
Warmest - coldest mean tempt
Annual tempt range
Tempt controls
Geog posi Altitude Albedo Cloud cover Ocean currents Differential heating of land and water
Lines that connect points of the same tempt
Isotherms
Primary control of daily tempt
Earth’s rotation
Most mechanical thermometers are based on ghe ability of a substance to
Expand when heated, contract when cooled
Instrument continuously recording temperature
Thermograph
Electrical thermometers use ts to measure tempt
Thermistor
Difft temperature scales use difft
Reference pts/fixed pts
Ic and steam pt of fahrenheit scale
32, 212
Tempt where all molecular motion is presumed to cease
Absolute zero
Ic and steam pt of kelvin
273 and 373
Common applications of tempt indices
Cooling, heating, growing
Each degree of tempt below 65 F is counted as one HD a day
Heating degree days
Subtracting 65 deg from daily mean
Cooling degree day
DMT - base tempt of crop = minimum tempt for it to grow
Growing degree days
Summertime discomfort links H and Tempt to determine thermal comf of human bod
Heat stress index, humidity, tempt
Uses w and a tempt to calculate human sensation of tempt
Wind chill
Additional and relatively rapid change induced by human acts
