ascending velocity
解釋
上升速度-
Analyzing the physics structure of vorticity, divergence, vertical velocity, frontogenesis " function, apparent heat source and apparent moist sink etc. indicated the physics fields are favorable for the occurance of the heavy rain over changjiang - huaihe river basin where the physics values are well according to the heavy rainstorm positions ; the low level jet is closely subject to the moisture and the coupled system of the low and the upper level jetstreams induced the strongly " ascending motion ; the intensity of the frontogenesis varies with the development of the rainfall system and reacts the rainfall intensity
主要分析了這次過程中的多種物理量，包括渦度、散度、垂直速度、鋒生函數、視熱源、視水汽匯等，對這一暴雨過程有了比較系統的認識。結果表明：在江淮流域存在著有利於發生暴雨的物理量場配置，渦度、散度、垂直速度等物理量，與暴雨的落區都很吻合的；低空急流的產生不僅有利於水汽的輸送，而且高低空急流的耦合造成了有利於強上升運動的配置；鋒生強度隨著降水系統的發展變化，並影響降水強度。 -
The result indicates that, in the course of the rainstorm in huoshan, there are obvious low - level jet of great intensity, infection of mesoscale shear line, enhancement of plus vorticity which increases intensity of convergence, improves ascending velocity and brings on precipitation, and quick enhancement of helicity which provides the basis to forecast, in addition, convergence of moisture flux and analyzed potential vorticity which reflects baroclinic convective instability sufficiently indicate the characteristics of the rainstorm
結果表明：此次霍山暴雨發生前後，存在明顯的大強度低空急流，並受到中尺度切變線的影響，而且正渦度的加強引起了輻合加劇，提高了上升速度從而引起降水，同時暴雨發生前螺旋度的迅速增強，也為預報提供了根據，另外水汽通量的輻合以及分析位渦反映出的斜壓對流不穩定都充分體現了這次降水的特點。 -
The paper works out the ice crystal spectrum distributing in the different macroscopic and micro - backgroud of the cloud ( ie, the thickness, the temperature and the supersaturation with respect to ice of the nucleation layer ). this paper also works out the amount of catalyst which is allowed in the cloud nucleation layer according to the different quantity of the supercooled water, the density of the supersaturation of the vapor with respect to ice. simultaneously, the paper discusses the i nfluence of remaining time when seeding artificial ice nucleus in the different ascending - velocity and altitude, and elicits the proper seeding altitude of the catalyst
以此解為依據，得出了不同均流時，人工引入冰核在核化層存留時間，再以此時間作為人工冰核凝華增長時間，求出不同的雲宏微觀背景（如核化層厚度、溫度、冰面過飽和度等）下的冰晶譜分佈，經和實際資料比對符合相當好。進而求出核化層中不同過冷水量、冰面過飽和水汽密度下雲核化層可允許的催化用量。同時討論了不同升速，不同高度引入人工冰核時對其存留時間的影響。 -
Test results show that the water surface slope, velocity and ratio of water depth to draft are the main influencing factors of ships ascending rapids
試驗結果表明，灘段的水面比降、水流速度及船舶水深吃水比是船舶上灘的主要影響因素。 -
Finally, it briefly discusses the feasibility, the applying foreground and the approach with regard to the calculating method about the amount of catalyst provided in this paper by integrating the ascending - velocity field and cloud water field in the possible working section abstracted from the mm5 mesoscale model with the thickness of the ice crystal particles in nucleation layer and supercooled water quantity which is surveyed by the plane
得出適合的催化劑引入高度等。最後，簡要討論了用mm5中尺度區域模式提取可能作業區的升速場和雲水量場，並結合飛機實測核化層冰晶粒子濃度、過冷水量等，探討了本文提出的催化劑用量計算方法的可行性，應用前景和途徑。 -
