What is the other term for the wave cyclone:
polar front cyclone
When the center of a mature wave cyclone passes to the south, you should expect:
an occluded front
The time scale for the life of a mid-latitude cyclone is about:
The polar front theory was developed what scientists during World War II:
The polar front separates what from what:
cold polar easterlies, warm mid-latitude westerlies
Meandering in the upper-level winds can lead to:
major cyclones and anticyclones
If there is more divergence aloft than convergence at the surface, what will what at the surface:
low pressure, strengthen
Anticyclones are typically associated with
clear skies and calm conditions
Much less study has been devoted to anticyclones as compared to cyclones:
When the upper air diverges, the surface cyclones may form
Occluded fronts characterize the beginning stages of a middle latitude cyclone
Cyclones are not common in the United States
The term cyclogenesis refers to the decay of a mid-latitude cyclone
Mid- Latitude cyclones normally bring abrupt changes in the wind, temperature, and clouds
The warm sector of a cyclone typically has clear skies
When upper level air speeds up, speed divergence occurs
Anticyclones always bring nice weather
A mid-latitude cyclone typically dissipates as it approaches the upper-level ridge
Upper-level ridges have low air pressure features
Upper-level convergence downwind of a trough leads to a high pressure at the surface
