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 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. A numerical model is used for obtaining the state of the atmosphere as close as possible to the observed one which is ensured through verification with surface and upper-air observations. The results indicate that the amplitude of warm inflow does have a significant influence on the Bora strength and its offshore reach within the onset period.
