Temperature Scales - CORRECT ANSWER Fahrenheit, Celsius, Kelvin
Temperature Conversions - CORRECT ANSWER C to K = C + 273
K to C = K - 273
C to F = 1.80C + 32
F to C = F-32/1.80
Major Lines of Longitude and Latitude - CORRECT ANSWER Latitude: equator, North Pole (90 N), South
Pole (90 S), Tropic of Cancer (23.5 N), Tropic of Capricorn (23.5 S), Arctic Circle (66.5 N), Antarctic Circle
(66.5 S)
Longitude: Prime meridian @ 0 & international date line @ 180
AOI and Zenith Angles - CORRECT ANSWER AOI refers to the angle at which the runs rays strike the Earth
Higher AOI = more direct sunlight and higher temp
Lower AOI = less direct sunlight as suns energy is dispersed over a larger area and lower temp
AOI changes approx 2 degrees every week
Zenith angle refers to the angle between the sun and the vertical angle
AOI + zenith always is 90
The larger AOI will result in a smaller zenith angle
Shortwave and long wave radiation - CORRECT ANSWER Shortwave = ultraviolet radiation, visible light
Contains lots of energy
Enters our atmosphere after the sun emits this massive amount of energy as UV rays
Measured using solar radiation sensors
, Longwace = infrared
Contains less energy than shortwave
Heat from absorbed shortwave is reradiated by Earth as long wave
Measured using IR
Albedo and its effect on temp - CORRECT ANSWER Amount of radiation a surface reflects
Dependent upon properties of the surface
High albedo = surface reflects the majority of the radiation that hits it and absorbs the rest (light
surfaces)
Low albedo = surface reflects a small amount of the incoming radiation and absorbs the rest (dark
surfaces)
Relative humidity and dew point - CORRECT ANSWER Relative humidity is the ratio of the amount of
water vapor in the air relative to the max amount of water possible (temp dependent, warm holds more
water vapor than cool)
Dew point is the temp at which a volume of air must be cooled to become saturated with water vapor
(not as dependent on weather)
Relationship between RH, DP, and temp - CORRECT ANSWER Relative humidity and temp have an
inverse relationship
Dew point is the temp the air needs to be cooled to achieve a relative humidity of 100%
Low and high pressure and weather - CORRECT ANSWER High - clockwise motion, associated with fair
weather, wind blows from high to low
