Winds
How wind typically blows....from what to what
High pressure to Low pressure
Which type temperature can hold more water vapor
Higher temperature air - it evaporates faster so it can hold more
Meterologist use this to measure temperature
Thermometer and Thermographs
Fivw most common forms of precipitation
rain, snow, sleet, hail, freezing rain
The measure of the amount of thermal energy in the air
What is Temperature?
Global winds that drive most US weather
Prevaliling westerlies
Due to uneven heating on surface, the push from high to low pressure is called this
pressure gradient force
Instrument used to measure air pressure
Barometer
If air is 100% saturated and temperature drops, this happens
Air will turn into tiny droplets of water that stick to dust particles - Condensation occurs.
Which scale starts with the assumed termperature of the body as 96*
Fahrenheit
Land absorbing sun's energy more rapidly than water
Sea Breezes
the measure of the amount of water vaport in the air
Humidity
This causes wind
The movement of air due to difference in air pressure
the rate at which air pressure changes with distance
Pressure gradient
(the larger the gradient, the stronger the wind)
As temperature goes up, what does pressure do?
It goes down.
This causes the paths winds follow between cyclones are anticyclones
The Coriolis effect
Relative humidity
How wind direction expressed
By directions - or degrees on a compass
(north, southwest, 90*)
Object like trees, buildings and mountains slow down winds - its called this
Friction effects
Freezing point of water in both F and C
32* and 0*
These air masses are associated with low pressure, cloudy, damp and stormy weather
What is warm air masses
Instrument used to measure humidity
hygrometer
This measures precipitation in mm of in of water
a rain gauge
The smalles rain drops
Drizzle (about .5 mm)
Weight of gases in the atomosphere bearing on Earth's surface
Pressure (atmospheric pressure)
