During the first week of June 2008 the
EUMETSAT sponsored training project
EUMeTrain organised a successful
event week on the topic of convection. This event week consisted of several
online sessions dealing with the nowcasting of convection from satellite. Guest
speakers were Martin Setvak, Marianne Koenig, Guy Kelman, John Mecikalski and
Kris Bedka. These speakers gave a half hour expert session on new developments
in the field of nowcasting convection which was then followed by a practical
session on how convection was nowcasted in an NMS in Europe.
For those of you have
missed this event, all the sessions have been recorded and can be downloaded
and play backed accordingly.
The playback software is provided by Centra (java-based), you do not need
to install anything!

Session
1:
The session includes presentations from Martin Setvak dealing with the MSG observations
of cold-ring shaped storms and their comparison with CAPPI radar data. More
information is found in this powerpoint. The session is continued by the Austrian
Meteorological Service (ZAMG) on severe convection and hailwarnings.
Session
2:
Guy Kelman (Hebrew University of Jerusalem) explained the relationship between
cloud top temperature and effective radius and emphasised the advantage this
can have on the lead time and the possibility to nowcast areas with a high potential
of severe convection. The session was followed by Wilfried Jacobs (DWD) on the
Automatic weather and product monitoring (Automon).
Session
3:
Same presentation as previous expect that Guy Kelman (Hebrew University of Jerusalem)
also showed some more examples of nowcasting convection over the States. . The
session was followed by a very good presentation of Natasa Strelec Mahovic (DHMZ)
who in depth presented what material and products the Forecaster have available
in Croatia when they start their working day and the day turns out to be convective.
Session
4:
Marianne Koenig (EUMETSAT) demonstrated the GII product. For the forecaster
this was a very interesting talk as it showed the advantages the use of GII
has to a model. Case studies saw the potential the GII product has and which
added value(!) the GII has to a normal model run. The session was followed by
Jenni Teittinen from the Finnish Meteorological Institute who talked about warnings
and the assessment of warnings in Finland.
Session
5:
Same talk by Marianne Koenig (EUMETSAT) on the GII product as in the morning.
The session was followed by Maurice Schmeitz from KNMI on the development and
verification of a new model output statistics (MOS) system, which is intended
to help the forecasters to decide whether a weather alarm for severe thunderstorms
should be issued.
Session
6:
Kris Bedka (University of Wisconsin) and John Mecikalski (University of Alabama)
gave a presentation on the Convective Initiation (CI) method. The CI product
identifies cumulus-type clouds within an MSG image and uses the temporal evolution
of the related MSG observations to identify rapidly growing cumulus as likely
candidates to evolve into potentially strong convective storms up to one hour
in the future. This session was continued by the Portuguese Met Service (IM).
Besides the diagnostic tools from Numerical Weather Prediction models currently
in use, satellite and radar products were addressed, including automatic warnings,
eg, for hail.
