A preliminary numerical simulation of bora wind with a limited area model of atmospheric circulation

One case of bora that burst out on the 4th of January 1995 has been simulat ed with a regional atmospheric model (RAMS). This was a typical bora with a stationary cyclone that remained over southern Adriatic Sea during the who le episode of bora. Some common features of bora such as upstream accelerat ion, strong descent within bora layer and turbulent zone just downstream of the mountain have been demonstrated by the model simulation. The simulatio n of the bora wind speed and direction showed good agreement with the obser vation in Trieste (Italy).
