And this is the second key to a cooling tower, convection.
- So just for the cost of spraying the water, you create this enormous natural convection in the tower, moving huge volumes of air into the bottom, up past the fill, and out at the top to reject large amounts of heat to the atmosphere.

Does Pressure Keep the Deep Ocean From Freezing?
- But for various reasons related to circulation and salinity and convection and the fact saltwater freezes into freshwater ice, for complicated reasons, deep ocean water is often around 0-4°C and doesn't really get much colder than 2 below 0.
