This document describes the required work steps tasks to carry out the control experiment and subsequent perturbation experiments on the ECMWF HPCFto simulate the extra-tropical evolution of Tropical Cyclone Karl.
In contrast to the yesterday's Acceptance Test experiment this does will not require an interactive session on the Cray's postprocessing nodenodes. We will submit the model control experiment as a batch job.
The Control Experiment
- We will use a pre-compiled and pre-installed version of OpenIFS 43r3 on the ECMWF's HPCF.
- We will carry out a 6-day (144 hours) control experiment
...
- starting on 25 Sep 2016
...
- at 00h00 UTC.
- We will use OpenIFS with a cubic octahedral grid at horizontal resolution Tco399 and 137 vertical levels.
- The control experiment will be initialised from ERA-5 reanalysis data.
Preparing the Model
In your working group you should login to the RACC cluster and login to the ECMWF HPCF with your training account ID.

The qstat command indicates the current status of your job in the batch scheduling system. The status is indicated by a capital letter. At the start the letter 'Q' indicates that your job is waiting in the queue to be processed. 'R' indicates that the job is now running. 'E' indicates that the job has stopped and is exiting.
