槽形低氣壓 的英文怎麼說
中文拼音 [cáoxíngdīqìyā]
槽形低氣壓
英文
trough-
The atmospheric circulation of the wet year deviate from enso year to no - enso year. in enso year, the subtropical high is strong with the deepening of trough over south of baikal lake while in no - enso year, the subtropical high is weak with the high incidence of typhoons over northwest of pacific and south china sea
多雨年發生在enso年和no - enso年大氣環流形式的不同主要表現在： enso年副熱帶高壓較強，貝加爾湖地區南部低壓槽容易加深；在no - enso年副熱帶高壓強度減弱，在西北太平洋和南海地區多熱帶系統活動。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。The occurrence of cirrocumulus clouds indicates the distant presence of a convergent zone such as a pressure tough or a cyclone in lower levels ; or a frontal zone where cold air meets moist warm air. vigorous convection and lifting motion bring water vapour up in the sky where the water vapour sublimes into ice crystals, forming the high clouds
卷積雲的出現顯示遠處地方低層有一強輻合帶如低壓槽或氣旋或鋒面即暖濕空氣碰到冷氣團，向上爬升的交界面形成，強烈的對流和抬升運動將水汽帶到高空，在那裡水汽直接升華變為冰晶而形成高層雲。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。Regional difference in lower - level temperature dv and pressure dv are greatly weakened and dv of llj is distinctly faint without the nanling ridge. this result show that nanling ridge acts as a critical role in the establishment of dv of the lower - level temperature and pressure, which give rise to the dv of llj in south china
而當模式中僅僅去掉南嶺和武夷山山脈地形后，低層大氣溫度場日變化的區域性差異明顯變弱，梅雨低壓帶南側原南嶺山脈所在地的溫度日較差明顯減小，使得梅雨低壓槽與華南地區之間的南北向水平溫度梯度和水平氣壓梯度的日較差顯著變小，導致華南低空急流日變化的顯著減弱。3 by delineating the various features of the weather maps and putting them into layers i. e., pressure cells, troughs, ridges etc, users can overcome visual information overloads by selecting appropriate layers of interest and animating them over time
將描述天氣地圖的不同特徵如氣壓單元，低壓槽和高壓脊並將其放入不同的層中，用戶可以選擇感興趣的圖層以避免可視信息過量，並使之以動畫形式表示。分享友人
