2. T= tropical
3. A= arctic
4. m= maritime
5. c= continental
●● 6 stages of mid latitude cyclone
Answer: 1. stationary front
2. frontal wave
3. open wave
4. mature (initial occlusion)
5. advanced occlusion
6. cut off cyclone
●● A downdraft is associated with sinking air.
Answer: true
●● A front is a boundary between air masses.
,Answer: true
●● A front is always accompanied by a sharp change in temperature.
Answer: false
●● adding mass
Answer: high pressure
●● air mass
Answer: -large body of air with similar temperature and humidity
characteristics
-often associated with with regions of calm winds and generally
flat/uniform topography
●● aloft, convergence occurs _____ of trough and divergence ______
Answer: upstream (left) and downstream (right)
●● along the gust from squall line:
Answer: winds can be very strong...especially in "bow"
●● both stationary and warm fronts can be related to ______
Answer: ice storms and bonds of precipitation
, ●● bow echoes
Answer: curved line of convection "bows" out
●● cA
Answer: -continental arctic
-extremely cold, dry, stable
-ice and snow around surface
-cold air rushed down into central U.S. from Canada
-causes lake effect snow and citrus crop damage
●● classic supercell
Answer: heavy rain, strong winds, large hail, tornadoes
●● cloud electrification steps:
Answer: 1. warmer hail/groupel transfers positive ions to colder ice
crystals
2. larger hailstones (negative) are heavier and fall, the lighter ice crystals
(positive) are lighter and are swept upward in draft
3. leads to charge seperation
●● cold air aloft means
Answer: -low pressure
-low heights
