Product description

These products are a subset of the full Catalogue of ECMWF Real-time Products and are based on the medium-range (high-resolution and ensemble) and seasonal forecast models.

Products are produced at 0.4 degrees resolution in GRIB2 format unless stated otherwise. 

Important: higher resolution versions of the same products are available via the Product Requirements Catalogue and are subject to the ECMWF Standard Licence Agreement.

 

High-resolution products:

Steps:

  • For times 00z &12z: 0 to 144 by 3, 150 to 240 by 6.
  • For times 06z & 18z: 0 to 90 by 3.

Single and Pressure Levels (hPa): 1000, 925, 850, 700, 500, 300, 250, 200, 50

Tropical cyclone tracks - ensemble products

The tropical cyclone trajectories are computed independently for each ensemble member; a given tropical cyclone may dissipate at different times in different members so the number of members predicting a given tropical cyclone may vary through the forecast.
