On the average, cold fronts are about twice as steep as warm fronts and travel slower than warm fronts.
|
False
|
|
Precipitation associated with a cold front usually occurs along a narrow zone.
|
True
|
|
Midlatitude cyclones that form east of the Rockies have a tendancy to northeastward path.
|
True
|
|
Cyclones form along fronts and proceed through a generally predictable life cycle.
|
True
|
|
On a weather map, occluded fronts are shown with blue triangular points on one side of a line and red semicircles on the other side of the line.
|
False
|
|
The most useful model of how a midlatitude cyclone developes is known as the polar-front theory.
|
True
|
|
When compared to cold fronts, warm fronts have a greater slope and produce heavier precipitation over a larger area.
|
False
|
|
Fronts are boundary surfaces that seperate air masses of different densities.
|
True
|
|
The first sign of an approaching warm front is often the appearance of nimbostratus clouds.
|
False
|
|
In a midlatitude cyclone, low pressure is centered at the apex of the "wave" where the fronts connect.
|
True
|
|
More often than not, the formation of a cyclone is initiated by the flow aloft in the vicinity of the midlatitude jet stream.
|
True
|
|
In the classic polar-front model, cyclogenesis occurs when cP air clashes with mT air along a front.
|
True
|
|
Cyclogenesis is closely related to convergence aloft.
|
False
|
|
When a rapidly moving cold front overtakes a warm front, an occluded front is likely to form.
|
True
|
|
Surface airflow in a Southern Hemisphere midlatitude cyclone is counterclockwise.
|
False
