cold dry air mass meets a warm humid air mass = cold front = cumulonimbus (tall storm clouds)= heavy rain ( sometimes severe weather, tornadoes)
thunderstorms
The amount of water vapor in the air is called
precipitation
clouds
humidity
What is humidity?
When water turns into a gas it's called?
evaporation
When water vapor turns back into water to form a cloud, this is called ________________.
condensation

is a wind vane
The weather forecaster for a local news station observes that the air pressure is rising. Which type of weather would he expect to see?
clear skies
cloudy skies
high humidity
thunderstorms
rising air pressure = high pressure = air cools, particles get close together and sink, no clouds =
clear skies
