Weather

Weather was the environmental conditions caused by the atmosphere.

Various incarnations of the Doctor encountered devices which could affect the weather, like the Gravitron, (TV: The Moonbase) the Weather Control Unit, (TV: The Seeds of Death) the Stormcore (PROSE: Drift) and the sonic screwdriver. (COMIC: Death to the Doctor!)

When opened the Eye of Harmony inside the Doctor's TARDIS on New Year's Eve 1999, it caused freak weather patterns all over Earth.

The Saturnyns attempted to control the weather in 1580 Venice to turn the Earth into their new home. (TV: The Vampires of Venice)
