Application of mesoscale model (MEMO) to the greater Zagreb area during summertime anticyclonic weather conditions

Abstract

A high-resolution insight in the flow patterns is necessary for the study of various urban to regional scale phenomena. In this study the applicability of nonhydrostatic mesoscale model MEMO (version 6) to the greater Zagreb area under summertime anticyclonic weather conditions is evaluated.  Results show that MEMO is able to simulate mesoscale wind flow reasonably well. Simulated wind fields gave a detailed illustration of the up- and down-slope circulation generated on south-facing slopes of the Medvednica Mountain. However, daytime surface wind speeds seem to be better predicted than the nighttime ones. Therefore, a further investigation related to the choice of some of the input model parameters is needed.
