Medium (15 days)

Medium range forecast section contains charts for up to 15 days time range from high resolution (HRES),, ensemble (ENS) and ocean wave forecast systems. Charts are categorized as"Forecast"and"Verification"charts.

IFS Medium-range Control forecast (Wave), formerly HRES-WAM and Analysis Data (15-days)

IFS Medium-range Control forecast (Wave) is coupled to the IFS Medium-range Control forecast and it provides direct output "High Frequency products":

  • 4 forecast runs per day (00/06/12/18) (see dissemination schedule for details)
  • 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.

 

Atmospheric model Ensemble 15-day forecast

Ensemble (ENS) of forecasts providing an estimate of the reliability of a single forecast. Currently there are 50 perturbed members in the ensemble.

ENS offers  "High Frequency products"  until step 144:

  • 4 daily runs: 00, 06, 12 and 18 UTC
  • hourly until step 90
  • 3-hourly from 93 to 144

Most Post-processed Products are not available at 06/18 runs or in hourly steps. An exception are Tropical Cycle tracks (set III-viii) which is available for all daily runs: 00, 06, 12 and 18 UTC.

IFS Medium-range Control forecast (formerly HRES) and Analysis Data (15-days)

Single prediction that uses

  • observations
  • prior information about the Earth-system
  • ECMWF's highest-resolution model

IFS Medium range Control forecast offers "High Frequency products"  

  • 4 forecast runs per day (00/06/12/18) (see dissemination schedule for details)
  • Hourly steps to step 90 for all four runs.
