Exercise 9

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:

one week

The polar front theory was developed what scientists during World War II:

scandinavian

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:

true

When the upper air diverges, the surface cyclones may form

true

Occluded fronts characterize the beginning stages of a middle latitude cyclone

false

Cyclones are not common in the United States

false

The term cyclogenesis refers to the decay of a mid-latitude cyclone

false

Mid- Latitude cyclones normally bring abrupt changes in the wind, temperature, and clouds

true

The warm sector of a cyclone typically has clear skies

true

When upper level air speeds up, speed divergence occurs

true

Anticyclones always bring nice weather

false

A mid-latitude cyclone typically dissipates as it approaches the upper-level ridge

true

Upper-level ridges have low air pressure features

false

Upper-level convergence downwind of a trough leads to a high pressure at the surface

true
