3 、東北地區出現春季低溫的主要環流特徵是：內蒙古高壓，阿留申低壓的強度加強；阿流申低壓指數以及東亞大槽強度指數減弱，東北地區從地面到對流層頂處在溫度負距平中心內，東北地區春季高溫時則出現與上面相反的變化形式。 -
The diagnostic analysis for the sandstorm process on the base of height, temperature, pressure and wind etc output from the model shows that the upper cold trough, low - level wind shear, surface cold anticyclonic ridge, mesoscale cyclone and cold front are the main synoptic systems, surface cold anticyclonic ridge and cold front provide condition of wind force to occurrence of the sandstorm weather, the strong mesoscale cyclone before front makes pressure gradient before and after cold front obviously strengthen, moreover, and it increases obviously the temperature of the controlled area, as a result, the updraft movement caused by convergence before front strengthens
500hpa強鋒區、 700hpa切變和鋒前中尺度系統的強弱及位置變化是沙塵暴天氣發生發展到減弱的直接原因。地面冷高壓、地面氣旋及冷鋒是造成本次沙塵暴天氣的主要地面天氣系統。地面冷高壓及冷鋒為沙塵暴天氣的發生提供了風力條件，而中尺度氣旋使冷鋒前後氣壓梯度明顯增強外，又使所控制的區域增溫明顯，使鋒前輻合上升運動加強，為沙塵暴天氣的發生提供了熱、動力條件。 -
Note : volume of the expansion trough is more than twice that of the increment due to expansion of oil in the entire heat exchanging system caused by working conditions. in this system the expansion grough is always at the highest top. volume of cold oil trough is approx. 1. 3 times of the system ' s total oil uantity. for specific installation mode and dimensions please consult our tech dept

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。 -

型槽結構在嚴寒高水位下穿立交引道的應用 -
The results show that the weather process occurs because of typhoon trough with cold air, deep upper trough ; the southeast low - jet by typhoon transported large water vapour and great energy of instability to heavy rainfaill area ; cold air, lower convergence and upper divergence by deep upper trough lead to development of the east - ocean low pressure and occurd strong wind
分析結果表明：這次天氣過程是由臺風倒槽和冷空氣及深厚的高空槽共同作用引起的；臺風環流引起的東南低空急流為暴雨區輸送了大量的水汽和不穩定能量；冷空氣的侵入加上深厚的高空槽引起的低空輻合、中高層輻散，促使了東海低壓的劇烈發展，產生了猛烈的大風。 -
In 1999, the dipole existed in between the okhotsk high and the depression in the north of northeast china, thus the okhotsk high became active and maintained, the subh was located to an area quite further south than usual. the high persisted in the east region of nw china, the cold air flowed to the mid - lower reaches of the yangtze river along the high. in the east region of nw china, air steam under troposphere was strong sinking motion, and formatted the negative vorticity region, the vapour flux divergence was divgence. lt was apparently that the rain could n ' t occur in the eastern portin of nw china. in 2000 year, okhotsk high was very weak or did n ' t exist in, there was high in the east asia - japan, the subh is located to an area further north than usual. in the east region of nw china, the trough maintained, air stream under troposphere was strong ascending motion, the cycolonic circulation was prevailing, the vapour flux divergence was intensive convergences the rain easy happened in the east areas of northwest china
4多梅雨1999年鄂霍茨克海阻塞高壓與我國東北北部低壓形成偶極子，使得阻塞高壓穩定少動，西太副高位置偏南，西北地區東部持續受高壓控制，冷空氣沿此高壓流經長江中下游地區上空；在西北地區東部對流層中下層氣流下沉運動較強，呈反氣旋渦度，水汽通量散度輻散，不利於西北地區東部降水。空梅雨2000年相反，鄂霍茨克海高壓減弱甚至不存在，東亞-日本為高壓，西太副高位置偏西偏北，西北地區東部處于西風槽中，對流層中下層氣流上升運動增強，盛行低壓環流，水汽通量散度強烈輻合，有利於降水生成。 -
In heavy snow years, there are marked anomaly of atmospheric circulation : on 500 height field trough of east asia is heavier, north - west flow after height trough is striver, so that cold air of eastern region is stronger following " cold winter '. spring rain answering to eurasia winter snow anomaly is notable, in heavy snow years, yangtse - river has negative rain anomaly
在歐亞冬季積雪異常偏重的年份，大氣環流出現顯著異常： 500hpa位勢高度場上徑向氣流占優勢，東亞大槽偏強，高度場槽后西北氣流偏強，造成影響我國東部地區的冷空氣偏強，出現「冷冬天氣」 。我國春季降水對歐亞冬季積雪異常的響應最為顯著，重雪年春季我國長江流域以南大部地區出現明顯的降水負異常。 -
Firstly, subtropical high center lay to the north than usual, and forms a blocking high in combination with land high in eastern asia. secondly, on account of the strong southwest current which occurred at the west side of the subtropical high and dynamic effect of the typhoon itself, the landing northward tropical cyclone ( 9711 ) landed in liaoning again. thirdly, a trough with some weak air from ural mountain and the northeast cold air entering into the tropical cyclone showed that the systems in different latitudes had some effects each other
模擬結果表明：此次熱帶風暴造成遼寧全省大暴雨的天氣背景是：副熱帶高壓偏北並與大陸高壓疊加，構成了穩定的東亞阻塞形勢； 9711臺風減弱的熱帶風暴，在其自身內力和副高西側的強盛偏南氣流引導下，持續北上並在遼寧營口至盤錦之間登陸；從烏拉爾山冷堆分裂南下出的弱冷空氣不斷南下，與熱帶風暴在遼寧產生了相互作用，增強了上升運動，致使大暴雨出現。 -
The computer model forecast weather maps are generated by the observatory s computer model directly without manual adjustment. hence, symbols for synoptic features such as cold fronts and trough lines are omitted
這些電腦模式預測天氣圖是由天文臺的電腦直接編制而成，不經人手修訂。因此預測圖內並沒有標示冷鋒和低壓槽等天氣系統。 -
