Numerical simulation of possible extreme events due to orography at Cyprus

For mesoscale processes within the range 50–1000 km, horizontal advective changes in density are small in comparison with vertical ones and anelastic condition is valid. This allows us to reduce the system of equations describing the three-dimensional problem of a stratified fluid motion over an arbitrary relief to a form suitable for calculation of the flow over Cyprus island. An analysis of real data shows that there are two of the most typical synoptic processes for Cyprus are West-to-East and South-to-North wind advections. The computed overflow pattern corresponds to the general influence of Cyprus mountains on atmospheric flow, which is also apparent from comparison with map of precipitation distribution.
