Firstly, this paper designs a polar coordinate barotropic vorticity equation semi - spectral model and a quasi - geostrophic grid model in order to research the propagation of vortex rossby waves and tropical cyclone intensity change entirely
本文首先設計了一個極坐標系正壓渦度方程的半譜模式、一個準地轉格點模式對渦旋rossby波傳播和熱帶氣旋強度變化進行了較為系統的研究。The salinity distribution characteristics are the high - salinity in the bohai bay and the low - salinity in the boahi strait. the density distribution shows that there is a large cyclonic density circulation in bohai sea and it is likely to exist some density current gyre in the middle part of the bohai sea. in winter the saddle - like pattern of the bohai sea temperature and salinity shows that the circulation structure is much complexer than the previous research results
密度分佈表明：夏季渤海灣口已經由以前的低密度中心變為現在的高密度中心，相應的環流結構也必會發生大的變化；夏季渤海中部會存在一個反氣旋式的密度環流，並在局部可能存在多個密度流渦環；冬季渤海「馬鞍狀」溫鹽結構反映其密度環流結構要比以往研究結果復雜得多。Secondly, a shallow - water model is designed to study the topographical effects on the propagating vortex rossby waves and tropical cyclone intensity change detailedly
之後設計了一個淺水模式較詳細地研究地形對渦旋rossby波傳播以及熱帶氣旋強度變化的影響。The principal contributions of this dissertation are : 1. a high fidelity and real - time rotor wake inflow model was built up. based on peters - he finite states wake theory, a new influence coefficient matrix for high speed flight was derived, the modified wake model is better suitable for the flight state with a large wake skew angle
本模型以peters - he有限狀態尾跡理論為基礎，修正了大尾跡傾斜角時的誘導速度影響系數矩陣，並結合了王氏渦流理論，導出了旋翼誘導速度垂向分量和旋轉分量的表達式，可計算平尾、尾槳和垂尾氣動中心處誘導速度各分量。分享友人
