weather test 2 Flashcards
the surface winds in a typical northern hemisphere high pressure system( anti-cyclone) are generally moving
clockwise away from the high pressure center
a low pressure system (cyclone) in the northern hemisphere has a surface air- circulation pattern that is
counter clockwise towards the center
the cariolis effect
because of the earths rotation winds bend to the right in the northern hemisphere and to the left in the southern hemisphere
cyclones
low pressure system
anti- cyclones
high pressure system
air mass
a large body of air with generally the same humidity and temperature they are named for their source region - where they form
dry and over land
continental
warm and around the equator
maritime
cold , high latitude
polar
extremely cold (frigid)
arctic
front
boundary between different air masses/ different densities
warm front
moves slowly
light and long lasting precipiatation
after front passes temperature increases
cold front
moves fastly
precipitation is heavy and brief
after front passes temperature decreases
temperature
thermometer
dew point/ relative humidity
