ATMOSPHERIC VARIABLES Temperature
Definition Average kinetic energy of molecules If moving fast Higher temperature If moving slow Lower temperature
Measuring Air Temperature Instrument: Units/Scales: ESRT p 13 Thermometer Fahrenheit (oF) Celsius (oC) Kelvin (oK)
Kelvin 0o K = - 273o C 0o K ~ - 460o F Absolute Zero -Temperature at which molecules stop moving Everything emits energy as long as the temp is above 0o K
