thermal advection 中文意思是什麼
thermal advection
解釋
熱平流-
The results show that vorticity advection, thermal advection and latent heat release made great contribution to the development of the depression
中低層的溫度平流、降水凝結釋放潛熱維持上升運動，是低壓進一步發展的有利條件。 -
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。 -
In addition to the thermal reasons, the advection of arctic sea ice ( pacific section ), which is the result of dynamic factors, is closely related to the frequency shift that occurred in chukchi sea
楚科奇海海冰范圍的年際變化中存在由低頻向高頻變化的現象，該現象除了在局地氣溫變化中存在之外，在北冰洋區域風渦度、波弗特海緯向風、東西伯利亞海經向風等動力因素中也有所體現。 -
As we all know, the heat transfer of geothermal heat exchanger ( ghe ) is affected by a lot of factors, where groundwater advection has a comparatively great impact indicated by experimental data. while almost all the design tools for ghe are based on principles of heat conduction and rely on some estimate of the ground thermal conductivity and volumetric specific heat. however, the large part of vertical u - type pipe lies in the saturated soil, especially in zones along the coast or with plentiful groundwater, which will be affected by groundwater advection greatly
但是對於垂直u型埋管來說，管段大部分位於土壤飽和區內，實際上其穿透的地層中總是存在著地下水的滲流，尤其是在沿海（河、湖泊）地區或地下水豐富的地區，埋管的傳熱性能大部分都受到地下水滲流的影響，此時土壤內發生的是熱傳導和地下水滲流共同作用下的復雜的、非穩定的傳熱傳質過程（簡稱熱滲耦合傳熱過程） 。
