Question

A cold ocean current means less what in the air?

Answer 1

A cold ocean current means less precipitation in the air and less rainfall. Hope this helps!=)

Answer 2

Gaseous compounds (like air) contain no force of their own, but their mass is a component of force. The force is usually created gravity or temperature conditions. I'll answer this the easy way. Fully inflate a balloon, tie off the opening, then put it in a freezer and wait 10 minutes. After this time, the size (or volume) of the balloon will be smaller, because the air inside now exerts less force on the inside of the balloon (at rest), even though the mass of the air inside the balloon did not change. Therefore, cold air has less force than hot air (of the same mass). If you switch the meaning of the question to one based on a constant volume of air (instead of a constant mass), then the answer flips around. That's because the density of cold air is higher than the density of hot air. That's why firemen tell you to crawl to escape a burning building. The hot (less dense) air rises, leaving the cooler, potentially survivable air at the floor level. Put another way, gravity "pulls" the cold air down (displaying force) below the hot air.
