The Weather Control Unit was a device in London's Weather Control Station. It was used to control the Earth's weather. As rain could destroy Martian seed pods, an Ice Warrior attacked the station and destroyed the unit. The Second Doctor bypassed the unit by reconnecting the wiring. This allowed him to initiate rain, destroying the pods. (TV: The Seeds of Death)
