capillary action
the ability of water to pull itself upward through small openings against gravity
hydrologic cycle
the circulation of water from one part of the general Earth system to another
saturation
when air of a given temperature holds all of the water vapor that it possibly can
capacity
maximum of water vapor
dew point
the temperature at which condensation takes place
humidity
amount of water vapor in the air at any one time and place
absolute humidity
the measure of the mass of water vapor that exists within a given volume of air
specific humidity
the mass of water vapor( given in grams) per mass of air
relative humidity
ratio between the amount of water vapor in a given temperature and the maximum amount of vapor that the air could hold at that temperature(water in air vs. could be in air)
transpiration
the way that plants give up water; source of atmospheric moisture
evapotranspiration
evaporation and transpiration together; accounted for all the water vapor
potential evapotranspiration
refers to idealized conditions in an area under which there should be sufficient moisture for all possible evapotranspiration to occur
condensation nuclei
minute particles in the atmosphere that provide a surface upon which condensation can take place
radiation fog/ surface inversion fog
radiation cooling; likely to occur on a cold, clear, calm night; mid-latitudes
advection fog
occurs through the movement of warm; moist air over a colder surface, either land or water; mid-laititudes during winter months
