| climate | the average weather conditions in an area; the weather conditions in an area over time |
| climate zone | a region on earth characterized by similar climate |
| climograph | a graphic representation of at least two climatic factors, most often mean values for precipitation and temperature for an area |
| dendrochronology | the study of annual growth rings in trees to infer conditions in past environments |
| dew point | the temperature at which water vapor begins, or would begin, to condense |
| ecosystem | a community or group of organisms living and interacting with each other and their environment |
| evaporation cooling | when the evaporation of water lowers the temperature of a liquid or object that it is in contact with |
| greenhouse effect | the process in which the absorption of short wave radiation by the atmosphere heats up a planet |
| leeward | on the side away from, or sheltered from, the wind |
| permafrost | a sublayer of soil that remains frozen year |
| prevailing winds | winds in the lower troposphere that generally flow from the same direction; westerlies are prevailing winds that blow from west to east |
| rain shadow | the side of a mountain that has a dry climate because precipitation falls mainly on the other side |
| relative humidity | the amount of water vapor in the air divided by the amount that would have to be present in the same air to form a cloud or condense on a surface |
| saturation | in air, the presence of the most water vapor possible under existing pressure and temperature |
| topography | the physical features of the land |
| urban heat island | the effect of the built environment of a city, including buildings, asphalt, and concrete, retaining heat and therefore maintaining a higher temperature than surrounding countryside; the city is a comparatively warm island amid cooler surrounds |
| weather | the conditions in the atmosphere at a particular place and time |
| windward | on the side toward, or exposed to, the wind |
