Question

9. Is it a cold front or warm front that is most closely associated with the following progression of cloud types: Ci, Cs, As, St, Ns? Which would be seen first as the front approaches, Ci or Ns?

10. ________ Compare an “average” cold front to an “average” warm front:

            A. Generally, cold fronts move faster than warm fronts.

            B. Generally, cold fronts have steeper slopes and, therefore, more convection.

            C. Generally, cumuliform clouds are more often associated with cold fronts.

            D. All of the above are true.

Explanation / Answer

9. The cloud progression is a typical example of a Warm front. Cirrus will be seen first in a warm front (in most cases cirrus clouds are the first signs of an approaching storm)

10. All the statements are correct

Cold fronts do move faster that warm fronts as the density of the cold front is more, hence the air molecules will hit each other in a more faster manner.

The slope of the cold front is about 1:80, and that of warm front is 1:150 due to this there will be a quicker conventional curents inside the front

Cumuliform clouds especially Cumilonimbus clouds are often associated with cold fronts as they have more convective power and hence the clouds can grow bigger and taller.
