, the Met Office has been using data over Europe from thousands of aircraft each day to improve weather forecasts. This data, known as Mode-S EHS, includes information such as wind speed, temperature, and aircraft position, which is collected during flights. Originally used for air traffic control
in the grid box (e.g. at the top of the BL). Achieves good performance without the need for EACF. Diagnostic cloud fraction. • Prognostic cloud, prognostic condensate (PC2) – developed in the late 90’s/early 00’s. Cloud fraction is a prognostic which allows increments to be made to it from other schemes

in the tropical Pacific Niño3.4 region (5°S–5°N, 120°W–170°W). Predicted positive anomalies in the Niño.3.4 region indicated the development of El Niño type conditions, and this was supported by international consensus, co-ordinated by the World Meteorological Organisation (WMO). El Niño conditions and below
