Wind field simulation in meteorological applications in Croatia

This paper describes two numerical models for computing the mesoscale influences of orography, friction and heating on the wind field. The DMI model is a diagnostic, one-level, primitive equation model and the DM2 is a mass-adjusted, three dimensional wind field model where interpolated three-dimensional mean winds are adjusted in a weighted least-squares sense to satisfy the continuity equation within the volume specified. The models are capable of simulating a broad scale of atmospheric phenomena such as orographic channelling, effects due to changes in atmospheric stability, land and sea breezes, and anabatic and katabatic winds. The main attention is paid to the performed models' applications for different purposes in the Meteorological Service of Croatia. The given application examples illustrate the broad spectrum of applications made possible by the models' flexibility in treating different weather situations and regions.
