偉劉德華生身於一個權傾朝野的顯赫世家,抗日戰爭期間,為將來政途鋪路而當上空軍,在一次送信任務中,意外地被日機轟中,迫得急降山區小村,為村姑小禾吳倩蓮所救,二人一見如故,悄悄地燃起愛火,可惜。( 5 ) the spring greenland sea - ice extent is larger ( smaller ) : then during the following summer the high of the japanese sea is stronger ( weaker ), and the low of the asian land is stronger ( weaker ), which make the pattern of low west and high east easily ( uneasily ) form ; the ascending movement over north china is strengthened ( weakened ) ; the summer monsoon of east asia is stronger ( weaker ), then the southeastern, warm and damp airflow towards the north china is stronger ( weaker ), and the cold airflow of the high level over the north china is also stronger ( weaker ), which make the convergence of the cold and warm air over north china easily ( uneasily ) form ; the sst of the east pacific ocean is lower ( higher ), while the sst of west wind drift is higher ( lower )
( 5 )春季格陵蘭海冰面積偏大(小) :後期夏季日本海高壓偏強(弱) ,而大陸上低壓也偏強(弱) ,易(不易)形成西低東阻的形勢;華北地區的上升運動增強(減弱) ;東亞夏季風偏強(弱) ,向華北地區輸送的西南暖濕氣流偏強(弱) ,而對應高空華北地區上空冷空氣活動偏強(弱) ,利於(不利於)華北上空冷暖空氣的交匯;夏季赤道東太平洋海溫偏低(高) ,西風漂流區海溫偏高(低) 。在以上的環流背景下,華北夏季降水偏多(少) ,易澇(旱) 。The analysis of the large - scale synoptic situation shows that strong precipitation is closely related to the explosion of monsoon and the intensification of cross - equatorial flow which bring a lot of vapor and meet with cold masses at the eastern of northwest district on 8th, june causing extremely heavy rainfall ; that subtropical high - level jet at 200hpa, subtropical high at 500hpa and low - level jet at 850hpa are the weather backgrounds favorable to strong precipitation ; that the pattern of eastern highs and western lows and the establishment of a low - level jet and the coupling between upper - and low - level patterns that determine that the rain occurred in the east of the northwest china ( on average, this is the rainy season for the south of china, but not for the northwest china ) ; that water vapor comes from southerly and easterly flow which converge at the eastern of northwest district with convergence mainly in lower levels and pbl ; that the high value of the whole - level apparent heat source < q1 > is near the area of large rainfall in the direction of northeasterly - southwesterly agreeable to shear line very well and the condensation latent heat releasing is main heat source with vertical advection item playing key role in q1 and q2 ; that there is a vertical secondary circulation crossing low - lever jet whose ascending branch is at the area of large rainfall ; that the construction of convection instability and conditional symmetry instability results that there is not only deep thermal instability, but also moisture influx and triggering mechanism of thermal instability causing strong torrential rain
作為對比,本文還對2002年6月24 - 25日發生在北京地區的強地形雨進行了分析,並討論陜南、北京地區兩地暴雨的異同點以及地形作用的共性和個性,為兩地暴雨預報提供有益的參考,得出了一些很有意義的結果: 1大尺度環流背景分析表明: ( 1 ) 「 02 . 6 」強降水與6月上旬越赤道氣流和季風爆發密切相關,攜帶大量水汽的偏南氣流與冷空氣於6月8日交匯在西北地區東部,導致了這次強降水的發生; ( 2 ) 200hpa的副熱帶西風急流、 500hpa副高以及850hpa的低空急流的配置非常有利於本文分析之陜西強降水的發展與維持。大尺度形勢分析表明,東高西低形勢場、低空急流的建立和高低空形勢的配置決定了這場降雨出現在西北地區東部。與暴雨區相聯系,存在一支橫越低空急流的經向垂直環流,暴雨區處于該垂直環流的上升支; ( 3 )偏南和偏東氣流水汽通道在西北地區東部交匯,水汽的輻合積聚主要在對流層低層和行星邊界層內完成; ( 4 )整層的視熱源< q _ 1 >高值區在暴雨區附近呈東北-西南向分佈,與切變線走向非常一致,降水產生的凝結潛熱釋放是強降水區大氣的主要熱源。The above analysis showed that this heavy rainfall event took on obvious meso - scale characters and was the combination of the three flows, so we can deduce : ( 1 ) surface southeasterly wind and topography may play the main role in this event ; ( 2 ) the easterly cold air rushing into the southern shaanxi province in the lower troposphere was strongly relative to the form of surface cold - front type of occlusion ; ( 3 ) there were two reasons for the secondary circulation ' s strengthen in the evening, one was the effect of a mountain - valley wind and the other may be latent heat leading to ascending motion ; ( 4 ) the shape of potential instability stratification corresponded well with the development of the warm - moisture advection ; and ( 5 ) the vapor providing essential thermodynamics was transported by a southwesterly low - level jet from the bay of bengal and the south china sea. furthermore, with the effect of terrain, the southern shaanxi province became the center of this extremely heavy rain process
中尺度結構分析表明,本次暴雨具有明顯的中尺度特徵,是由三支氣流共同作用的結果,分析發現( 1 )地面東南風和地形在這次大暴雨過程起主要作用; ( 2 )東路冷空氣主要是通過中低層侵入陜南地區的,並與地面冷式錮囚鋒的形成密不可分; ( 3 )夜博士論文:中尺度地形對陜南暴雨的影響研究間垂直次級環流發展加強可能有兩個原因,一個是由於地形山谷風的作用,另一個是降水的潛熱釋放激發了上升運動: ( 4 )位勢不穩定層結的形成與低層暖濕平流的發展有很好的對應關系; ( 5 )本次暴雨的水汽主要靠偏南風急流將孟加拉灣和中國南海的水汽輸送至西北地區東部,為暴雨的發生提供了必要熱力條件。Under clear skies, light winds and dry conditions, temperatures over exposed areas in the new territories can drop appreciably overnight because of radiation cooling
在天朗氣清微風及乾燥的情況下,有利輻射冷卻,所以新界的空曠地區可出現顯著降溫。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。For instance, hot weather and rising air can help dispersion of air pollutants ; rainfall can wash out certain pollutants in the air ; an occasional phenomenon known as temperature inversion can trap air pollutants in the lower atmosphere ; and still wind conditions can inhibit effective dispersion of air pollutants. moreover, when a weak northerly wind prevails in southern china, the impact of regional air pollution on hong kong will become more serious
例如,炎熱天氣和上升的空氣有助空氣污染物消散;降雨可沖走空氣中部份的污染物;偶爾出現的逆溫層現象能把空氣污染物困在大氣的低層;風靜的情況可引致空氣污染物不能有效消散;及當華南地區吹微弱北風時,整個香港受區域性空氣污染問題影響也會特別嚴重。分享友人
