Some words about weather and weather phenomena.

Note that weather usually involves verbs in Klingon—for example, SIS rain is a verb (it rains, it is raining) and there is no specific word for the noun rain.

If you wanted to specify that a specific puddle, for example, was formed from rain and not some other source of water, you could call it chal bIQ sky water, but that's more of a description than a separate word for rain.

Note that English needs a dummy subject it with weather verbs (it is raining, it snowed, etc.) but Klingon does not: SIStaH, peD etc. are quite sufficient. Don't use 'oH as there is no it there which does the raining.

Serious weather predictions use the verb 'aq, which indicates a kind of prediction that is carried out on the basis of science, research, or deductive reasoning, rather than guesswork or gut feeling.

If the specific person or group who made the forecast is not named, the construction is usually … 'e' 'aqlu' It is predicted that …, though … net 'aq is also possible.
