摘要
General features of 3-dimensional mesoscale wind and temperature structure over ShandongPeninsula are described in this paper.Results are achieved by numerical simulation with the 3-dimensional non-hydrostatic mesoscale model METRAS.For the onset and cessation time of sea-land breezes,the simulation results agree well with the statistical analyses of observational dataavailable for the studied area.One interesting result is the 3 hour response time of wind field to thethermal change.Further statistic analysis based on the observational data is needed to make sure ofthis correlation.Important effects of coastal mountains on the wind structure are also exposed indetail by the model.Convergence and divergence centers resulting from the conjunction of sea-landbreezes and complex terrain are clearly shown,which are not noticed before by conventionalsynoptic observation and theoretical analysis.
