Answer:
temperature 
Explanation:
I choose temperature because it tells how hot,cold,dry and warm somethings are meanwhile evaporation is when water changes from liquid to gas,so that means water gets hot.
 Precipitation is when water released from the cloud to form rain,freezing rain,sleet,snow,or hail.Which means thing get cold.
Air pressure also affect evaporation, which means that water will not be able to come up of the surface of a body of water.So that means the the pressure will be pushing down on the surface of the water.
