Pokémon are pretty amazing creatures. One of the crazier things they can do is change the weather, by using a particular move or because of their Ability. Similarly, some Pokémon can change the properties of the terrain they're battling on. Hmm, that's a lot of power in the hands of somebody who apparently skips school...
Changes to the weather will apply to all Pokémon in battle. Only one weather condition can be present at one time. If a Pokémon's move or Ability changes the weather, it will replace the previous weather condition.

If a Pokémon with the Cloud Nine or Air Lock Ability is present during battle, the weather will revert to normal and Pokémon will be unable to change the weather.
Terrain effects apply to all non-Flying or Levitate Pokémon in battle. Like weather conditions, there can only be one terrain effect at a given time. However, terrain effects can overlap with weather conditions (for example, there can be Intense Sun and Psychic Terrain simultaneously).
