The Climate Flashcards
(35 cards)
Weather
Combination of temperature, humidity, precipitation, wind, cloudiness, and other atmospheric conditions at a specific place and time
Climate
The long term average patterns of weather
All objects omit radiant energy, but the nature of the energy depends on the objects what?
Temperature
The _____ The object, the more energetic the omitted photons in the shorter the wavelength of energy
Hotter
The sun primarily gets off what kind of radiation?
Shortwave
The earths surface gives off what kind of radiation?
Longwave
Of the radiation that reaches the top of earths atmosphere what percent makes it to the surface?
51%
How many units of solar energy does the atmosphere reflect back
26
How many units of solar energy does the atmosphere absorb
19
How many units of solar energy does the earths surface reflect back
4
How many units of solar energy does the earth surface absorb
51
Of the 51 units absorbed by the earth how many are used up and water evaporation
23
Of the 51 units absorbed by the earth how many units warm the air near the surface
7
Of the 51 units absorbed by the earth how many are absorbed by land and water
21
How many units of solar radiation does the earth emit per 51 units absorbed
117
Greenhouse effect
The process by which radiation from the planets atmosphere warms the planet surface temperature above what it would be without an atmosphere
Because of ________ the earth receives twice as much long with radiation from the atmosphere compared to shortwave radiation from the sun
Greenhouse effect
What influences the moisture in the air?
Temperature
Absolute humidity
Amount of water in a given volume of air
Relative humidity
The amount of water in a given volume of air expressed as a percentage of the saturation vapor pressure
Precipitation is determined by
- temperature, wind, and current
- warm trade winds moving toward the equator pick up more water vapor
- rising winds at the equator cool, lowering the water that can be held in the air
Proximity to the coast line influences what?
Climate
Why do land surface is cool more rapidly than bodies of water?
Water has a high heat capacity: it takes four times more thermal energy to raise water by 1°C compared to land
Do you land areas farther from the water experience greater or less seasonal variations in temperature compared to coast
Greater
