| Abstract: | The intent of this study is to develop a better understanding of the behavior of late spring through early fall marine layer
stratus and fog at Vandenberg Air Force Base, which accounts for a majority of aviation forecasting difficulties. The main
objective was to use Leipper (1995) study as a starting point to evaluate synoptic and mesoscale processes involved, and identify specific meteorological
parameters that affected the behavior of marine layer stratus and fog. After identifying those parameters, the study evaluates
how well the various weather models forecast them. The main conclusion of this study is that weak upper-air dynamic features
work with boundary layer motions to influence marine layer behavior. It highlights the importance of correctly forecasting
the surface temperature by showing how it ties directly to the wind field. That wind field, modified by the local terrain,
establishes the low-level convergence and divergence pattern and the resulting marine layer cloud thicknesses and visibilities. |
