After opening this workshop on Friday evening a minute of silence was held in honour of Thomas Hafner, who died much to young and would be sadly missed by all his gliding friends.
1. Forecasts for Gliding
Integrating thermal driven local wind systems (foothillls of the alpine regions, seabreezes) will be the next step of development.
Forecasters from the flat areas have requested that the influence of the surface-effects should be taken into considerations.
2. Internet-homepage www.pa.op.dlr.de/ostiv/
Martin informed about what is new on our homepage:
guestbook: for comments and questions, please look at this page from time to time and give your clever comments or answers.
If you have something new about OSTIV activities or projects, please feed our webmaster Martin, then he will update our homepage!
Status quo: during the Championships at Bayreuth obviously not all copies were sold by Thomas. Erland will be getting in touch with Thomas` wife in the near future. After getting the available copies we should all do our best to sell them.
For those who have an internet connection our "Handbuch" can also be downloaded.
future work: this Handbuch (or the english version?) should be updated continuously by our working group. In this case it will be necessary to change the format.
Wolf Dieter gave an impressive overview of the Mountain Wave Project in Argentina (at this time Klaus Ohlmann is flying world records again..). Carsten presented a cross-section showing the up and downdrafts in the trapped leewaves of the Andes. Very interesting, that it is not always the primary wave which has the strongest lift. It seems that due to the complex terrain the interferences produce also very complex wave strucures. To verify this, further measurements are necessary.
Mountain waves during south foehn conditions over the Alps were studied by two students from the University of Vienna. Analysing the files from the dataloggers of some cross-country flights is a first step towards a "climatology" of wave positions.
The Scorer-parameter for wave forecasting was evaluated and found to be a very helpful tool, which is now also available in the PC-Met.
future work: what about other wave phenomena, not orografically influenced ?
