This data is produced using relevant atmospheric model profiles and surface parameters from the operational high-resolution forecast. These are used to calculate brightness temperatures, which can be visualised as simulated satellite images.
5 Μαρ 2024 · Our aim is to stop using the term ‘high-resolution forecast’, or HRES, as all members of the ensemble are now also at 9 km horizontal resolution. For the next IFS upgrade, Cycle 49r1, planned for October 2024, the HRES and the ENS control are being made bit identical.
Latest forecast. Rain and mean sea level pressure. Precipitation totals include all precipitation types (rain, snow etc.) (in mm of rainfall or rainfall equivalent) falling in 6 hour or 12 hour periods using colour shading...
Hourly steps to step 90 for all four runs. The model computes between the latitudes -78 and 90, the output grid is artificially extended to -90. The purchase of the "Basic Set" +72, +96, +120, +144, +168 hrs is a mandatory prerequisite for the purchase of time steps in the range 12 to 66 hours.
Latest forecast. Simulated images (infrared) and 850 hPa wet bulb potential temperature. 850 hPa wet-bulb potential temperature is commonly used to identify air masses and a strong gradient of wet bulb potential temperature is indicative of fronts between two different air masses... Latest forecast.
Experimental: AIFS (ECMWF) ML model: 500 hPa geopotential height and 850 hPa temperature. AIFS (ECMWF): a deep learning-based system developed by ECMWF. It is initialised with ECMWF HRES analysis. AIFS operates at 0.25° resolution. Latest forecast.
The ensemble member forecasts are available between 90 and 120 minutes after the main run. ECMWF IFS HRES 0z/12z (10 days) - Current model charts of parameter "Significant Weather" for map "Texas".
