| 摘 要： | In this paper,a simulation study is made on the sea breeze process over southwestern Bohai Gulf byuse of the Pielke mesoscale meteorological model.The simulated results show that when a south wind of 8m/s blows over the top of the model,a strong wind zone of 15—25 km wide with a maximum speed more than14 m/s,which is close and nearly parallel to the south shore,will appear at 160 m above the sea surface.When a strong sea breeze penetrates inland,there often appears a thermal internal boundary layer(TIBL)near shore.The inversion above the TIBL can damp the vertical dispersion of atmospheric pollution.Besides,it is also found that,for a three-dimensional sea/land breeze circulation,if the divergence centre inthe return flow departs vertically far from the correspondent convergence centre in the sea breeze,a centre ofstrong descending movement will be formed at the middle and upper levels of the return flow.The resultsin this paper is also applicable to the Laizhou Bay.

| Abstract: | In this paper,a simulation study is made on the sea breeze process over southwestern Bohai Gulf by use of the Pielke mesoscale meteorological model.The simulated results show that when a south wind of 8 m/s blows over the top of the model,a strong wind zone of 15-25 km wide with a maximum speed more than 14 m/s,which is close and nearly parallel to the south shore,will appear at 160 m above the sea surface.When a strong sea breeze penetrates inland,there often appears a thermal internal boundary layer (TIBL)near shore.The inversion above the TIBL can damp the vertical dispersion of atmospheric pollution.Besides,it is also found that,for a three-dimensional sea/land breeze circulation,if the divergence centre in the return flow departs vertically far from the correspondent convergence centre in the sea breeze,a centre of strong descending movement will be formed at the middle and upper levels of the return flow.The results in this paper is also applicable to the Laizhou Bay. |
