is the measure of how hot or cold the air is.
Air temperature
is the weight of Earth's atmosphere pressing down on the surface from all angles.
Barometric Pressure
is the measure of how much water vapor is present in the air.
Humidity
is the movement of air from high pressure to low pressure areas.
Wind
these clouds are big, white, and puffy. They generally mean good weather.
Cumulus
Air temperature can be measured with a
thermometer
When there is high barometric pressure, the temperature is
hotter
Higher humidity means higher chance of
precipitation
The difference in what? Determines the speed of the wind.
air pressure
These clouds are thin and wispy. They generally mean good weather.
Cirrus
Most thermometers use two different scales.
Celsius and
Fahrenheit
When there is low barometric pressure, the temperature is
colder
is used to measure humidity
hygrometer
are used to measure wind speed.
Anemometers
These clouds are low, flat, and take up much of the sky. These clouds may produce drizzle or light rain.
Stratus
When air temperature is higher, the weather is
warmer
are used to measure air pressure.
Barometers
If Winds traveling to the south represent a warm front. Air pressure will rise resulting in fair weather.
Winds traveling to what? Represent a cold front. Air pressure will drop and chance of storms increase.
North
The type of precipitation depends on air
temperature
These clouds are very tall clouds. They can cause violent thunderstorms with heavy rain, hail, and possibly tornados.
Cumulonimbus
When air temperature is lower, the weather is
colder
Rising air pressure =
good weather
are used to measure the direction of the wind.
Wind vanes
are used to measure the amount of precipitation.
Rain gauges
There are a lot of factors that affect weather, so it can change very quickly over what period of time.
