摘要: Abstract The Regional Atmospheric Modeling System (RAMS) was run at a 1-km grid spacing over the Sydney basin in Australia to assess impact of land cover change on simulated storm event. used NCEP–NCAR reanalysis data, first with natural (i.e., pre-European settlement 1788) and then satellite-derived representing Sydney's current use pattern. An intense convective develops model close proximity dense urban central business district under cover. is absent conditions. A detailed investigation why generates performed using factorial analysis, which revealed be sensitive presence agricultural southwest domain. This area interacts sea breeze affects horizontal divergence moisture convergence—the triggering mechanisms storm. existence ur...
