摘要: The two-month special observing period of the Mesoscale Alpine Programme (MAP) in autumn 1999 included a variety complex mountain wave events. Seven events were carefully analyzed, compared with numerical models and described published papers. These detailed investigations revealed some common dynamical elements, i.e. importance low-level processes involving slow-moving boundary layer, wind shear causing either absorption or decoupling/spilling, upstream blocking, latent heat release. Based on these studies, it is clear that any quantitative prediction generation must take full account lower troposphere processes. newest show significant skill simulating effects. Using models, climatology waves over Alps can be studied. Copyright © 2007 Royal Meteorological Society
