2018-06-01 The new version of the LAM-EPS run by DMI

The new version of the  LAM-EPS run by DMI was implemented.The first affected runs in TIGGE-LAM archive are on 2018-05-22. The major changes:

  • new ensemble system based on the convection permitting HARMONIE-AROME model

  • outputs up to +42h

  • 1 less parameter for TIGGE-LAM archive as the large scale precipitation does not exist any more in the the convection permitting system

  • 2 newly provided parameters for TIGGE-LAM archive CAPE and CIN

2018-05-15 COSMO-DE-EPS replaced by COSMO-D2-EPS

The new set-up of COSMO model ("COSMO-D2") replaces the former COSMO-DE.  Methods of EPS member generation has not changed. The major changes:

  • grid spacing reduced from 2.8 km to 2.2 km
  • number of vertical levels increased from 50 to 65 with higher resolution in the boundary layer
  • model domain enlarged, mainly to the west

The updated description is available here.

2017-03-21 COSMO-DE-EPS model update

Following major changes apply to COSMO-DE-EPS update:

  • the use of four global models via BCEPS for initial and boundary conditions is switched off
  • initial conditions are provided by analysis members of an Local Ensemble Transform Kalman Filter
  • boundary conditions are provided by members of ICON-EPS (40 km grid size with a two-way nested grid of 20 km over Europe)
  • additional parameters of physics packages are perturbed
  • selection out of a set of predefined parameter perturbations is randomized (selection performed for each forecast start)
  • stochastic perturbations of SST and soil-moisture on specific spatial scales

The model description is available here.

2016-11-08 MOGREPS model update

The MOGREPS-UK forecasts were extended to T+54 (from T+36) starting from 9UTC run on 2016-11-08.

The updated description is available here.

2016-11-07 HUNEPS model update

The major changes in HUNEPS LAM ensemble system were implemented:
  • ENS boundary conditions used instead of PEARP ones
  • new 2 meter diagnostics improving 2 meter temperature forecast

The updated description is available here.

2015-01-20 COSMO-DE-EPS model update

The global model GME has been replaced by the new global model ICON. This change affects the COSMO-DE-EPS  because four global models (including ICON, GME before) are used to perturbat IC and BC (dynamically downscaled with BC-EPS). The updated description is available here.
