Print-out of the reading.
Air usually moves from areas of higher pressure to areas of lower pressure.
This makes sense - just like when the elastic walls of the balloon are squeezing air inside a balloon. If you let go of the opening of a balloon, 'wind' blows out from the higher pressure area inside the balloon to the lower pressure area outside the balloon. The water at the surface of the oceans is warmer than deeper water. The warmer, lighter water 'floats' on top of the colder, denser water. If winds blow in one particular direction for a long period of time, much of the warm surface water will be moved.
