Science
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.
