Question

Answer or explain the following in light of the principles

(l) Cloud droplets growing by condensation near the base of a cloud affect each other primarily by their combined influence on the ambient air rather than by direct interactions. [Hint: consider the average separation between small cloud droplets.]

(bb) Natural snow crystals are often composed of more than one basic ice crystal habit.

(jj) The melting level is a prominent feature in radar imagery.

Answer 1

1. Droplets are far apart within the cloud so direct interaction is not so much as their combined influence on the ambient air.

2. It depends on temperature. Natural snow crystals form around for below freezing point. So temperature determines where it is a flat or round

3. As the snowflakes fall they tend to go through a level where the temperature rises. They therefore produce a narrow band of high reflectivity in radar imagery
