We can use the mm5 model in definite time, definite area weather forecasting. we conclude that : : the moving route of this necw in its developing progress was direct - south along latitude, the cold air is rough, and just this made the rough vertical velocity ; the necw southern moving and conflicting with the west pacification sub - tropical high makes rough jet steam. the plenty south - west warm and wet air made by the jet stream gave the rainstorm demanded vapor ;. the rough vertical velocity by jet stream is a main reason in this rainstorm ; the mm5 model uses four - direction analysis data as its input, this avoids some errors occurred in observe and transfer, thus made the result more useful
綜合分析認為： （ 1 ） 、這次冷渦在其發生發展過程中，其移動路徑是沿經圈直線南壓，攜帶的冷空氣勢力較強，形成槽后較強的垂直運動； （ 2 ） 、西太平洋副熱帶高壓偏北位置與東北冷渦南壓形成的急流軸，把源源不斷的西南暖濕氣流輸送到遼西地區，也就是急流軸的左前方位置，為這次暴雨的產生提供了充足的水汽來源； （ 3 ） 、低空急流不但為暴雨輸送水汽，其造成的較強的垂直環流也是產生強降水的一個主要原因； （ 4 ） 、 mm5模式以四維同化資料作為初始場，最大限度地避免了觀測誤差可能造成的積分不穩定，提高了模擬結果的參考價值。Based on t213 and other observational datasets, a severe heavy rain occurred in changjiang - huaihe basins during 4 - 5 july 2003 is studied. the primary diagnostic analyses show that double or single block is the characteristics of the macroscale circulation in this rainfall process. the strong conflict of warm and cold mass, mesoscale convergence on meiyu front, shear line, and stably maintaining of high and low jets make for the rainfall
本文採用地面高空常規資料，每6h一次的降水資料，以及t213數值預報資料，對2003年7月4 - 5日發生在江淮地區的一次梅雨鋒暴雨過程的影響系統及其可能機制進行了初步的診斷分析，發現，高緯雙阻、單阻形勢是這次暴雨過程發生的大尺度環流特徵；冷暖空氣的激烈交鋒、梅雨鋒上的中尺度輻合線、 700hpa 、 850hpa上的低渦、切變線以及穩定維持的高低空急流是導致這場暴雨的直接影響系統；該地區維持一個高能、飽和、潛在不穩定的環境，有利於特大暴雨的產生和維持。The main relative systems of heavy - hard rainfall in northeast plateau are western pacific subtropical high, south asia high, low latitude systems, upper level jet ( ulj ), low level greater wind speed axes, westerly trough and plateau trough, low level vortex, cold frontal, occluded front in qinghai lake, mesoscale low pressure, heat low - pressure in qinghai, shear line and convergence line, mesoscale cloud cluster, etc. the west subsidiary model of south asia high is the main circulation type of heavy - hard rainfall in this area
3 、西太平洋副高、南亞高壓、低緯系統、高空急流、低空大風速軸；西風槽和高原槽、低渦、冷鋒、青海湖錮囚鋒以及中尺度低壓、青海熱低壓、切變線與輻合線、中尺度雲團等系統是高原東北部地區大到暴雨的主要相關系統。 100hpa上的南亞高壓中心強度加強，位置東西擺動預示高原地區將有降水產生，中心強度減弱，降水過程結束。南亞高壓西部副型是高原東北部地區大到暴雨的主要流型。Considering that the infiltration capacity curve can ' t express the actual infiltration capacity, the authors develop the surface runoff yield models that combine with the infiltration capacity curve, unstable raining process and antecedent soil moisture in each rainfall or over a duration time
考慮到流域實際的下滲能力，建立了將下滲能力曲線、不穩定降雨過程和前期土壤含水量有機聯系起來的流域場（時段）暴雨地表徑流計算模式。The soil - water characteristic curve, the coefficient of saturated hydraulic conductivity and the initial state of medium ; in the paper, the influence of rain infiltration on the slope stability is discussed, which is very helpful for forecasting slope stability in raining seasons and designing slopes in deep unsaturated zone
）介質的本身性質，如土水特性曲線、飽和滲透系數、及介質的初始狀態；通過本文的研究，初步分析探討了降雨入滲對邊坡穩定性的影響，為在雨季邊坡失穩的預報和具有深厚非飽和區的邊坡的設計提供了科學的依據，具有一定的工程意義。To decide the process and factors affected runoff and the characteristic of water erosion of large dump which produced during construction of railway engineering, study of natural rainfall for hezhuang dump in beitongpu railway rebuilding project is made during raining season
摘要以北同蒲增建二線改造工程河莊棄土場作為研究對象，在雨季進行了天然降雨試驗研究，確定了項目建設產生的棄土場區域內產流過程及影響因素和土壤侵蝕特徵。分享友人
