Project Cumulus
Project Cumulus was a 1950s UK government initiative to investigate weather manipulation, in particular through cloud seeding experiments. Known jokingly internally as Operation Witch Doctor,[1] the project was operational between 1949 and 1952.
Motivation
The military were controlling the weather for several reasons, as detailed in the minutes of an Air Ministry meeting held on 3 November 1953.[1] They included:
- "bogging down enemy movement";
- "incrementing the water flow in rivers and streams to hinder or stop enemy crossings";
- clearing fog from airfields.
Lynmouth disaster
On 16 August 1952 a severe flood occurred in the town of Lynmouth in north Devon. Nine inches (229 millimetres) of rain fell within twenty-four hours:[2] "Ninety million tonnes of water swept down the narrow valley into Lynmouth" and the East Lyn River rose rapidly and burst its banks.[3] Thirty-five people died and many buildings and bridges were seriously damaged. According to the BBC, "North Devon experienced 250 times the normal August rainfall in 1952."[3]
A conspiracy theory has circulated that the flood was caused by secret cloud seeding experiments conducted by the Royal Air Force.[1][4] The theory has been dismissed as "preposterous" by experts.[5]
