Definitions
the atmosphereic conditions, along with short-term changes, of a certain place at a certain time
Weather
boundary between 2 air masses
front
study and predict weather use temp, air pressure, wind speed, humitity, and percipitation to describe a variety of atmosphereic conditions
meterologists
air sinks warmer temps
high pressure system
large bodies of air that have uniform temp, humidity, and pressure
air masses
what are three things that describe air masses
consistent in temp, humidity, and pressure
take on characteristics of earth as they form
affect the weather of an area when meet
the weight of molecules in a large mass of air
air pressure
what type of weather is associated with low-pressure systems?
clouds and precipitation
air rises, cooler temps
low pressure system
what would tell scientists that two colliding air masses may cause a tornado
large differences in temp, humidity, and air pressure
