Air Pressure & Wind
Air Pressure & Wind
Fronts
100
the temperature at which air is saturated with water vapor
dew point
100
the amount of water vapor in a given volume of air, usually expressed as grams per cubic meter (g/m3)
absolute humidity
100
air that is moving from a region of higher pressure to a region of lower pressure
wind
100
a tool used to measure atmospheric pressure
barometer
100
a boundary between a cold air mass and a warm air mass that is not moving
stationary front
200
water droplets that form on surfaces due to condensation of water vapor
dew
200
the ratio, usually expressed as a percentage, of the actual amount of water vapor in air to the maximum amount of water vapor air can hold at the same temperature
relative humidity
200
a tool used to measure wind speed
anemometer
200
a circulation of matter, such as air, caused by constantly rising warm matter and falling cool matter
convection cell
200
a weather front in which a warm air mass advances to replace a cold air mass
warm front
300
the movement of water through the Earth system
water cycle
300
the formation of a solid structure whose atoms or molecules are arranged in a repeating, three-dimensional pattern
crystallization
300
the weight of the air pushing down on an area; the force exerted over an area by all of the air above that area
atmospheric pressure
300
working model of a design solution that can be used for testing and refining the design
prototype
300
a boundary between one warm air mass and two cold air masses, in which the warm air mass is pushed above the two cold air masses
occluded front
400
water located underground that fills pore spaces in soil and rock layers
groundwater
400
solid or liquid water that falls from clouds to the ground
precipitation
400
a property of matter that is equal to the amount of mass in a certain volume of matter
density
400
The scale that we use to determine the wind speed without a tool. This system uses a numbers system to access the wind speed.
Beaufort scale
400
a weather front in which a cold air mass advances to replace a warm air mass
cold front
500
the evaporation of water from the leaves of plants
transpiration
500
a huge volume of air that has a uniform temperature and humidity at a given altitude
air mass
500
the elevation of the land surface where the atmosphere meets the ocean
sea level
500
The name of a storm that travels across the ocean, bringing high winds.
Hurricane/Tropical Storm
500
the boundary where two air masses meet
weather front
