Superstorm is a three-part British docudrama miniseries written and directed by Julian Simpson, about a group of scientists that try to divert and weaken hurricanes using cloud seeding. Superstorm originally aired on BBC One for a period of three weeks, totaling three 59 minute episodes, from to . Each episode was followed by a half-hour documentary on BBC Two on extreme weather monitoring and forecasting, called The Science of Superstorms. The series was also aired (after being edited for content) on the Discovery Channel in the U.S. and Canada during the summer of 2007. Superstorm is a co-production of BBC Worldwide, Discovery Channel and ProSieben, in association with M6 and NHK. Ailsa Orr and Michael Mosley, who made also Supervolcano, are the executive producers for BBC, while Jack E. Smith is the executive producer for the Discovery Channel. The miniseries was released on DVD in the United Kingdom on 2 July 2007. Plot The movie begins with a team of scientists working on a US government project, known as Stormshield, whose goal is to control and manage storms, particularly hurricanes. Hurricane Grace, a Category 3 hurricane which is slowly climbing to a Category 5, is up to hit the United States. Using a predictive technology named Tempest and developed by Lance Resznick, they are able to simulate the effects of seeding the storm in order to collapse the eye of the storm and then decrease its intensity. Lance is openly skeptical towards the theories of Sara Hughes, an English scientist who is convinced about the effectiveness of cloud seeding. An experiment is done on a smaller hurricane, Agatha. A plane and several UAV carrying the seeds (in this case, supercooled liquid) fly into the storm. At first, the experiment is a success but then the storm intensifies during the seeding and the plane crashes. Weeks go by and Grace has now become a category 5 hurricane, headed straight for Miami. At the urgings of Katzenberg, the fund seeker of the project, the team formulates a plan of distant atmospheric perturbation to deflect Grace out into the Atlantic Ocean by creating a low pressure system on the Pacific coast and allowing it to be carried across the nation towards the hurricane. While the team leader Abrams and mathematician Munish Loomba try to model the weather perturbation that will safely deflect Grace, Lance tells Sara that her attempt to change Agatha's course
