The Numerical Forecast For The Sea Surface Wind In ZHOUSHAN Sea Area

ZHOUSHAN maritime space of archipelago scattering and gullet intervein lies in median latitude, which has complex terrain geographic and atmosphere-sea electrophoresis and has frequency gale doubtless weather. ZHOUSHAN harbor has radiate sector geographical conditions, which is indispensable to be an international ship hinge harbor in our country, intemation and Asia and Pacific. Now, ZHOUSHAN has been harbor of transiting and storaging oil. With increasing of coming-and-going ship, it's venture of overflowing oil in the offing is increasing, ZHOUSHAN area is the best place for all kinds of fish-shrimp breeding and inhabiting. ZHOUSHAN is sea area which fertility is tiptop in our country. Sea surface wind is important factor of influencing contrail of excursion oil and culturist So investigating sea surface wind of ZHOUSHAN and setting up numerical forecast model which fits this sea area can offer tool for study sea wind in this area and let us has a mensurable acquaintance ship of effect degree of physics factors which effect sea surface wind in ZHOUSHAN sea area and acquaint oneself with physic process.The task selects the up to the minute mesoscale numerical model as our forecasting model and use thrice fixed nesting and terrain datum of down to dale (highest precision data of 30s) as our terrain datum in the endothecium. With highest respective boundary PBL parameter scheme, we devise five test projects: control experiment and sensitive experiments without sensible heat flux, without latent heat flux, without sensible and latent heat flux, without terrain. By contrasting these simulative results, the experiments check up the forcing of heat flux and complex terrain to sea surface wind. At last, case A selects T106 datum to forecast by using KZSY real time numerical experiment.The first chapter introduces the signification of working over ZHOUSHAN sea area sea surface wind and state-in-art and technical route. The second chapter explains the mesoscale atmosphere model-MM5V3, remark the mode system and controlling equations and emphases introduce the upswing of every module in order to fit ZHOUSHAN sea area. The third chapter introduces the physical mechanism of sea surface wind firstly, then simulate five cases and contrast all results. Based on the third chapter, the fourth chapter forecast case A with T213 datum and KZSY test and analyses the result in detail. The fifth chapter sum up the article and view the work.The Simulation results indicate:(1) Exchanging of sea-air and force of dynamical and thermodynamic processes is very important to bring and maintain sea surface wind .SHF is mostly energy sources and LHF is negative effect in some area.(2) Increasing of wind is mainly induced by SHF and affecting of LHF is very little.(3) Effect of terrain increases ground rough and tonsure of terrain press and fiction correspond enhance frictional damp effect. The terrain effect force wind's speed reducing and wind's direction turning to leftWith contrasting the experiments of numerical simulation the text analyses the structure and microcosmic character of sea wind in ZHOUSHAN maritime space and consanguineous connection between sea wind and action of dynamical and thermodynamic .The task gets the result of case A by using T213 datum of weather center and contrasts it with the actual sea wind .The task establish a foundation in order to use this mode in the environmental forecasting.
