Creating forecasts is a complex process which is constantly being updated.
It involves the application of technology and detailed meteorological knowledge of how the atmosphere, the Earth's surface and the oceans work.
Modern weather forecasting applies scientific knowledge to predict future atmospheric conditions across the globe from observations of the current state, made from land; at sea; in the air, and from space.

The Unified Model Technical Infrastructure team develop and support the model infrastructure and integrate scientific developments into code releases.
Ever since the Unified Model was introduced operationally, in 1991, it has been in continual development. Infrastructure development is vital to enable the pull-through of scientific advances in both climate and weather prediction and to take advantage of steadily increasing supercomputer power. The Unified Model Technical Infrastructure team assess each scientific and technical development, ensuring that the proposed change meets defined software standards, the specified design requirement and maintains the integrity of the Unified Model system. Once approved the team integrates the change into the Unified Model system.
The coordination of Unified Model system code developments, from early stages through to implementation, are managed using the Met Office Flexible Configuration Management (FCM) system; as used for many Met Office software systems. The FCM is a software system for managing an building source code, developed at the Met Office using popular open source tools (e.g. Subversion, Trac and GNU make).
