troposphere n.【氣象學】對流層。

tropospheric

The effect of horizontal component in moisture potential vorticity is larger than that of vertical component . that is a big difference between torrential rain in summer and snowstorm in winter . the instability in the middle and lower layer of troposphere is one of the triggers in snowstorm 進一步分析表明,條件性對稱不穩定判據濕位渦的兩個分量中,水平分量在暴雪產生過程中所起作用要大于垂直分量,這是與夏季暴雨過程中得到的結論截然不同的。

While south asia high on the upper level of troposphere extends eastwards or retreats westwards during summer , 500hpa height field , 850hpa wind anomalies and vertical velocity field show obvious differences , and summer precipitation distribution in china is also different ( 2 )當夏季對流層高層南亞高壓處于偏東和偏西異常位置時, 500hpa高度場、 850hpa距平風場、垂直速度場都存在明顯差異。我國夏季降水量距平分布也有明顯差異。

Chemical mechanism on formation of secondary organic aerosols involves in photooxidation process of volatile organic compounds and subsequent chemical reaction , which directly lead to increase of ozone concentration and to formation of secondary organic aerosol in troposphere 二次有機氣溶膠形成的化學機理主要涉及到揮發性有機化合物的光氧化過程及其一系列的后續反應,它們導致了對流層中臭氧濃度的增加和二次有機氣溶膠的形成。

The results show that mesoscale low level jet , the perturbation in the high level troposphere can enhance and accelarate occurrence and development of mesoscale system ; convergence of low level and divergence of higher level are dynamical condition of storm rainfall system 本文的研究結果表明,中尺度低空急流、高空擾動對中尺度低渦系統的發生發展有加強和促進作用;低層輻合和高層輻散是降水系統的發展的動力條件。

When a volcano erupts , wooden hanger ( ecvv gold supplier ) wooden hanger ( k130 - 6 ) ( ecvv gold supplier ) wooden hanger ( k130 - 3 ) ( ecvv gold supplier ) dust is blasted [ 3 ] high above the troposphere and may take weeks to be carried around the weather zone , so cannot be washed out of the air by rain 火山爆發時,塵埃被高高噴射入對流層以上的空間,需要幾個星期才飄浮移至氣象層,因而雨水無法將其從大氣中沖走。

When a volcano erupts , dust is blasted [ 3 ] high above the troposphere and may take weeks to be carried around the weather zone , vmax swivel sweeper gceb20b ( ecvv gold supplier ) wooden hanger ( ecvv gold supplier ) wooden hanger ( ecvv gold supplier ) cannot be washed out of the air by rain 火山爆發時,塵埃被高高噴射入對流層以上的空間,需要幾個星期才飄浮移至氣象層,因而雨水無法將其從大氣中沖走。

It was a typical mei - yu front on the middle and upper level of the troposphere which became wider with the height increased . the temperature field of mei - yu front area looked like “ sandwich “ with the warmer air along the each side of the colder air of mei - yu area 在水平方向,梅雨鋒區的溫度場在對流層中低層呈現“暖-冷-暖”的“三明治”結構,即梅雨鋒區溫度最低,而在其兩側溫度最高。

That is to say , the so - called drought trend in the east of nwc , is not only point to the evolution of precipitation on the ground in the long term , but also to the vapor content in the whole troposphere 這是上世紀九十年代中后期天水重大干旱事件發生的一個背景條件。這說明,所謂西北地區東部干旱化的趨勢,不僅表現在地面降水量的長期演變方面,而且表現在對流層整層水汽含量方面。

But in flood years , the convergences in mid - and low - level of troposphere are strong . divergence departure in 200hpa is positive , so the pumping cause the updraft stronger . as we all know , the updraft is better to the rain 澇年對流層中下層輻合偏強, zoohpa上,高原東北側地區為正散度距平區,輻散較常年偏強,高空輻散抽吸作用使得該區盛行上升氣流,有利于降水的形成。

The remarkable transition of circulation type from winter to summer in middle stratosphere is from cyclonic type to anticyclone type . this is also the notable characteristic which is different from the transition in low stratosphere and troposphere 因此,在由冬到夏或由夏到冬的某個階段,該層環流流型出現由氣旋向反氣旋或由反氣旋向氣旋型環流轉變的過程。

( 2 ) in the lower level of the troposphere , the center of the cross - equatorial flows ( cefs ) is located at 925hpa other than 850hpa while it is at 150hpa instead of 200hpa in the upper level ( 2 )越赤道氣流的中心在低層位于925hpa而非850hpa ,高層位于150hpa而非200hpa 。東半球的越赤道氣流是一種典型的季風型越赤道氣流,而西半球越赤道氣流則為信風型。

Fourthly , by an analysis of log - amplitude scintillation due to troposphere turbulent , it is shown that the relative humidity and temperature are the major factor impacted on log - amplitude scintillation , at microwave and millimeter - wave band 第四,根據大氣湍流理論分析了在微波和毫米波波段影響幅度閃爍的主要因素是大氣相對濕度和溫度。

Forecast weather maps ( hereafter “ weather maps “ for short ) produced by the hong kong observatory cover east asia and the western pacific , and through the depth of the troposphere from surface to 12 , 000 m aloft 天氣預測圖,水平范圍涵蓋東亞及西太平洋地區,分辨率為六十公里,垂直方向由地面伸展至一萬二千米的高空。

Toms ai images and the atmospheric background circulations suggest that biomass burning plumes in south asia are transported to kunming and cause the enhancement of ozone concentrations in the lower troposphere 這與以往研究中東南亞地區生物體燃燒導致華南地區對流層低層臭氧濃度異常增高有所不同。

When a volcano erupts , dust is blasted [ 3 ] high above the troposphere and may take weeks to be carried around the weather zone , so cannot be washed out of the air by rain 火山爆發時,塵埃被高高噴射入對流層以上的空間,需要幾個星期才飄浮移至氣象層,因而雨水無法將其從大氣中沖走。

3 . the relation between the transition dates in middle stratosphere and the important systems in troposphere such as polar vortex and the subtropical high in west pacific 臭氧總量異常與中平流層轉型日期異常之間為反相關關系,臭氧總量偏高(低) ,流型轉型日期偏早(晚) 。

3 . there exists distinct statistical relationship between precipitation of each summer month and prophase atmosphere general circulation in troposphere and low stratosphere 青藏高原東北側地區夏季各月降水量同對流層、平流層前期環流特征之間存在明顯的統計相關。

The squall line is a kind of instable and strong convective weather caused by the air with upper - layer dry and lower - layer wet in front of the upper - troposphere trough 分析指出,該颮線系統是由高空槽前型的上干下濕引起的不穩定強對流天氣。

Ozone enhancement was observed in the lower troposphere over kunming on 21 march 2001 using electrochemical concentration cell ozonesondes 摘要2001 - 03 - 21在昆明用電化學臭氧探空儀探測到了對流層低層異常的高濃度臭氧分布。
