Differences between the wind, a wind, winds and wind?

I often come across the different uses of the word 'wind' in terms of grammar or any other nouns of similar character in various contexts. I think I understand the roles of definite and indefinite articles in general and such, but then always get this itchy uncomfortable feeling that I still don't fully get the hang of it.

For example, a weather forecaster would say 'winds' as in: "Sunday: Partly cloudy with light winds and still cool."
Why not wind, a wind, or the wind? There seem to exist subtle differences like this in nuance and meaning in hundreds of thousands of contexts, and the simple strategy of making myself exposed to as many examples as possible by reading only seems to have reached its threshold.

Any advice on how to improve the situation?
