Question

Which of the following is true for high clouds?

Answer 1

The answer is B. They do not usually bring precipitation. High clouds appear in the highest levels of the troposphere. They are most brilliant white due to the ice crystals in this level. Sunlight passes through high clouds most of the time as it's thickness is relatively thin

Answer 2

I would say that sunlight mostly passes through high clouds and also that the types of high clouds include cirrus, cirro-cumulus and cirro-stratus. When there is high clouds I believe that the weather is usually better than with the lower cumulus clouds which seem to result in more precipitation.
