the description of the state of the atmosphere at a specific time and place. This is the result of heat and Earth's air and water.
how fast the molecules move. High = fast movement, low= slow movement
high temps=low pressure
air moving in a specific direction
the amount of water vapor in the air
* warm air can hold more moisture*
the measure of the amount of water vapor in the air compared to the amount needed for saturation at a specific temperature. When relative humidity is 100 then the air is saturated.
the temperature at which air is saturated and condensation forms. This changes with the amount of water vapor in the air. Measured with a psychrometer (dry bulb and wet bulb)
objects that form as warm air rises, expands, and then cools. classified by shape and height
water falling from clouds
types of precipitation
rain, snow, sleet, hail
rain drops that pass through a layer of frozen air near Earth's surface forming pellets. (first rain then ice)
