Any small disturbance in a stationary frontal In wave cyclones, _____ fronts usually catch up to and
pattern, caused by _____ heating, irregular _____ overtake slower moving _____ fronts. This overtaking
produces what is known as a cold-type occluded front.
or high altitude _____, can start a wave-like bend
A. cold, warm
in the front.
B. warm, cold
A. uneven, terrain, winds (the jet stream)
C. warm, stationary
B. frontal, winds, fog
C. irregular, air, winds (the jet stream) 236. [L56/1/6]
As the cold occlusion develops, _____ air is lifted higher
230. and higher.
If a wave-like bend in a stationary front is energetic A. cold
B. warm
enough, _____ air rises over the retreating _____ air.
C. stationary
This often leads to _____, and the release of latent

heat into the atmosphere which intensifies the low

pressure system. Cold occlusions form predominantly over continents
A. cold, warmer, evaporation or along the _____ and are more common than warm
B. cooler, warmer, sublimation occlusions.
C. warm, colder, condensation A. northern territories
B. east coast
C. west coast

In a wave cyclone, advancing cold air (cold front) usually
Warm Occlusions
moves _____ than retreating cool air.
A. much slower 238. [L56/2/2]
B. slower Warm-type occluded fronts (or warm occlusions) begin
C. faster with _____ masses from the Pacific overtaking a retreating
colder air mass from the Arctic while _____ air is caught in
232. between these moving air masses.
A. cold air, warmer
The faster moving cold front in a wave cyclone eventually
B. stationary, colder
catches up with and overtakes the slower warm front.
C. warm, cold
Meteorologists call this an _____.

A. occlusion 239. [L57/1/1]
B. evolution Weather associated with a warm front occlusion has
C. inversion characteristics of both _____ and _____ fronts.
A. stationary, cold

C. warm, dewpoint
Sometimes multiple storm systems (several wave
cyclones) form along the polar front. These move
