weather Flashcards
?ic conditions, along with short term changes, of a ? place at a ? time.
atmospheric conditions, along with short term changes, of a certain place at a certain time.
important factors of weather ??? Air Density also play an important role in how weather happens. Cold Air= more? Warm air=less ?
air, water, heat
Air Density also play an important role in how weather happens.
Cold Air= more dense (sinks)
Warm air=less dense (rises).
?ist- scientist who study and predict weather
Meteorologist- scientist who study and predict weather
Air temperature- measure of the ? energy of molecules in the air.
Air pressure- the force that a column of air applies on the air or the surface ? it.
measured using ?meter
Air temperature- measure of the kinetic energy of molecules in the air. High temps=high kinetic energy
Air pressure- the force that a column of air applies on the air or the surface below it.
measured using a barometer
Wind- moving air, caused by differences in ?
Wind is measured using an ?meter
Wind directions-direction which wind is ?
Wind- moving air, caused by differences in air pressure
Wind is measured using an anemometer
Wind directions-direction which wind is blowing
Humidity- the amount of water in the air. When humidity is high there is more water in the air.
Relative humidity (RH)- comparison of the maximum amount of water vapor to the minimum amount of water vapor at a certain temperature.
Measured using ?
Humidity- the amount of water in the air. When humidity is high there is more water in the air.
Relative humidity (RH)- comparison of the maximum amount of water vapor to the minimum amount of water vapor at a certain temperature.
Measured using psychrometer
Dew point- the temperature at which air must be ? to become ?ed (holding as much water as can be absorbed) with water vapor.
it helps meteorologists figure out the amount of moisture in the air.
Dew point- the temperature at which air must be cooled to become saturated (holding as much water as can be absorbed) with water vapor.
it helps meteorologists figure out the amount of moisture in the air.
higher the dew point temperature,the ?er the amount of water vapor is present
higher the dew point temperature,the greater the amount of water vapor is present
higher the dew point temperature,the ?er the amount of water vapor is present
higher the dew point temperature,the greater the amount of water vapor is present
Clouds- water droplets or ice crystals suspended in the atmosphere formed around ???
a cloud that forms near earth’s surface is called ?
Clouds- water droplets or ice crystals suspended in the atmosphere formed around dust, salt or smoke.
a cloud that forms near earth’s surface is called fog.
Precipitation- water in liquid or solid form that falls from the ?
? air pressure usually forms clouds and precipitation.
Clouds form whenever the amount of water in the air is such that the humidity goes above ?%, or the ? point is reached.
Precipitation- water in liquid or solid form that falls from the atmosphere.
Low air pressure usually forms clouds and precipitation.
Clouds form whenever the amount of water in the air is such that the humidity goes above 100%, or the dew point is reached.
Air temperature- rises: evaporation, lowers: condensation Air Pressure- Warm air rises, air pressure ? Wind - Carries ??? Makes clouds visible, gives water molecules something to cling to Dew Point- Air cools to this temp: ?tion achieved
Air temperature-
rises: evaporation, lowers: condensation
Air Pressure-
Warm air rises, air pressure lowers
Wind -
Carries dust, salt, smoke,
Makes clouds visible, gives water molecules something to cling to
Dew Point-
Air cools to this temp: saturation achieved
