Projects:
Wind power in Central America
Sikorsky Helicopter accident outside Tallin
Air-quality analyses of stable weather situations
More research around MM5 (WRF) -> Lorenzo
LAPS-MM5 (but this on standby)
Case analyses for investigation (Fennia)
More research and development of MM5 thanks to Lorenzo Claveri
Work within EU-project (3 years in Helsinki)
Main objectives to start with are:
- How to handle surface temperature (SST/Skin temp.)
- Sea ice; correctness of data input and effect on MM5
- First test case; Pori and also surrounding coastal area, investigating stable condition and low-level jet
