Numerical simulation of possible extreme events due to orography at Cyprus

For mesoscale processes within the range 50-1000 km, horizontal advective c hanges in density are small in comparison with vertical ones and anelastic condition is valid This allows us to reduce the system of equations describ ing the three-dimensional problem of a stratified fluid motion over an arbi trary relief to a form suitable for calculation of the flow over Cyprus isl and An analysis of real data shows that there are two of the most typical s ynoptic processes for Cyprus are West-to-East and South-to-North wind advec tions. The computed overflow pattern corresponds to the general influence o f Cyprus mountains on atmospheric now, which is also apparent from comparis on with map of precipitation distribution (C) 1999 Elsevier Science Ltd.
