TESTED
Precipitation - CORRECT ANSWER-the input to our hydrologic cycle
lapse rates - CORRECT ANSWER-Rates at which air cools and warms.
Ideal Gas Law - CORRECT ANSWER-PV=nRT; predicts that air temp drops at high elevations
because air pressure is lower
cold air: - CORRECT ANSWER-holds less water vapor than warm air
saturation vapor pressure - CORRECT ANSWER-Maximum amount of water air will hold
(warm air hold more water than cold air)
saturated vapor pressure = actual vapor pressure at - CORRECT ANSWER-15 degrees C
General Atmospheric Circulation - CORRECT ANSWER-Global wind pattern modified by
continental masses, mountain ranges, seasons, Coriolis effect
most atmospheric circulation is driven by: - CORRECT ANSWER-differential solar heating
orographic precipitation - CORRECT ANSWER-Precipitation caused by winds blowing warm,
moist air toward coastal mountains; results when warm air rises over the mountains and cools
enough to form clouds that release rain and snow. Ex: Smoky Mountains
Convective storms occur most frequently - CORRECT ANSWER-in areas that are affected by
maritime tropical air masses and high humidity. aka thunderstorms
Tropical Cyclones (Hurricanes) - CORRECT ANSWER--Large rotating masses of low pressure
-Strong winds, torrential rain
-Classified by maximum sustained wind speed
-tropical depressions
Frontal storms (mid-latitude cyclones) - CORRECT ANSWER-fronts that occur when
contrasting temperatures and precipitation meet at the boundaries of different latitudes. Usually
when polar air masses meet tropical air masses.
mesoscale convective complexes - CORRECT ANSWER-very large cluster of self-propagating
storms; very intense rainfall over large areas
lake effect precipitation - CORRECT ANSWER-water is warmer than air, so cold air moves
over lake causing unstable conditions resulting in cumulus clouds that gather on downwind side
and precipitation occurs
precipitation varies by: - CORRECT ANSWER-geographic and temporal variation
, frequency curves - CORRECT ANSWER-a method of characterizing temporal variations, by
plotting depth of rainfall versus a specific duration
Rainfall Intensity - CORRECT ANSWER-The rate of precipitation, expressed in inches per
hour. Also known as precipitation intensity or storm intensity.
greater the intensity of a rainfall= - CORRECT ANSWER-the less likely it is to last a long time
Evapotranspiration - CORRECT ANSWER-The combined amount of evaporation and
transpiration
Evaporation - CORRECT ANSWER-The change of a substance from a liquid to a gas. Driven by
solar radiation
evaporation rate - CORRECT ANSWER-The rate at which a liquid loses mass at a given
temperature, pressure, and humidity.
evaporation can be slowed by - CORRECT ANSWER-laying mulch on fields
transpiration - CORRECT ANSWER-in plants, the loss of water through stomata
canopy interception - CORRECT ANSWER-rainfall that is intercepted by the canopy of a tree
and successively evaporates from the leaves
Potential Evapotranspiration (PET) - CORRECT ANSWER-an estimate of the average amount
of water that would evaporate from a hypothetical agricultural field over the course of a year
watershed studies - CORRECT ANSWER-all land in a given landscape that drains into a
particular stream, river, lake, or wetland
Actual Evapotranspiration (AET) - CORRECT ANSWER-the combined value of surface
evaporation and transpiration
field water budgets - CORRECT ANSWER-a tool to account for the storage and use of soil
water on a daily basis
gas flux measurements - CORRECT ANSWER-estimates the water loss in a plant
watershed divide - CORRECT ANSWER-higher elevation (ridge) separating two watersheds
Mean annual runoff - CORRECT ANSWER-subtract evapotranspiration from precipitation
mean annual flow - CORRECT ANSWER-increases linearly with basin area
