Abstract: Recent diagnostic and numerical studies have been shown that cyclogensis events in the lee of the Alps occur when: 1) an upper-level trough is upstream: 2) a low-level frontal system impinges on the Alps and, 3) an upper-level ...

Abstract: A series of numerical experiments were performed to test the evolution of lee cyclones with various terrain representations, and also to test forecast sensitivity to initial wind fields. Using the data set collected during ...

Abstract: s new observation systems are developed and deployed, new and presumably more precise information is becoming available for weather forecasting and climate monitoring. To take advantage of these new observations, it is ...
