Sažetak
There are several modifiers of the bora wind at the eastern coast of the Adriatic, but common to the majority of situations with bora are the cross-coast pressure gradient and cold advection on the continent. In this paper a detailed analysis of numerical model simulations of two cases with bora is presented in terms of the two aforementioned background state parameters, and additionally on the warm advection into the Adriatic basin. The results indicate that the speed of the bora wind offshore does not depend on the origin of the air within the jet. It is found that warm air from aloft can enter the accelerating streamline at the mountain ridge and continue as bora jet offshore. The pressure gradient across the mountain barrier is found to be an excellent indicator of the bora wind speed with correlation of up to 0.98.
