輻向通風
英文
radial ventilation-
Fanned by a constant updraught of ventilation between the kitchen and the chimneyflue, ignition was communicated from the faggots of precombustible fuel to polyhedral masses of bituminous coal, containing in compressed mineral form the foliated fossilised decidua of primeval forests which had in turn derived their vegetative existence from the sun, primal source of heat radiant, transmitted through omnipresent luminiferous diathermanous ether
自廚房至煙囪的孔道，不斷地向上通風，灼熱的火被它煽得從成束的易燃柴禾延燒到多面體煙煤堆上。這種煤炭含有原始森林的落葉堆積后凝縮而成的礦物狀化石森林之發育生長靠的是熱輻射性源-太陽，而熱又是由那普遍存在傳光並透熱的能媒33傳導的。Based on the epwp and wpwp in conjunction with abnormal north and west wind, a new possible iii mechanism is provided for the evolution of the 1997 / 1998 el nino. to be specific, the warm kelvin wave propagating to east excited by the abnormal west wind can suppress the cold upwelling flow in the eastern pacific, which, in turn, is favorable to the eastern pacific sst increase ; abnormal west wind can make the warm water of the wpwp east edge extend to east, which is conductive directly to eastern pacific sst increase ; the abnormal west wind propagating to east can make the sea surface warm water near two equatorial laterals converge to the equator by ekman drifting, which, in rum, strengthens the downwelling flow near the equator, leading to eastern pacific sst increase
將東、西太平洋暖池及異常北風、西風一併結合起來考慮，提出1997 1998elnino事件發生、發展的一種新的可能機制：異常西風激發東傳的暖kelvin波對東太平洋的冷上翻流有抑制作用，從而有利於東太平洋海表溫度增加；異常西風驅動西太平洋暖池東端暖水向東伸展直接有利於東太平洋海表溫度增加；東傳的異常西風可以通過埃克曼漂流效應將赤道兩側的海表暖水向赤道輻合從而加強了赤道附近的下沉流，也有利於東太平洋赤道附近海表溫度增加。It was well known that the main process of precipitation formation was collecting cloud water in the warm area and ice phase particles melting in the cold area. positive vertical velocity existed between 700hpa and 500hpa in the warm area and near surface in the cold area. wind convergence existed at the height of 700hpa, and divergence existed above and below the height of 700hpa
通過對降水雲系的綜合研究，建立了河南省春季層狀雲降水概念模型：暖區降水主要通過雲水碰並形成，冷區降水機制以冰粒子融化等冷雲過程為主;暖區700一50ohpa通常有上升氣流，冷區上升氣流分佈在近地面附近: 700沖a存在風場的輻合，其上下則主要是輻散區;水汽主要集中在7o0hpa高度上，暖區水汽來自南、東南方向，冷區水汽以西南輸送為主;暖區位勢不穩定分佈在o 。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。Diagnostic results show that the westerly wind stress anomaly and convergent meridional wind stress anomaly over the tropical pacific correspond to the every el nino, and the easterly anomaly and divergent meridional wind stress anomaly correspond to the vanishing of el nino
通過研究表明，每次elnino事件在熱帶太平洋都伴隨著西風應力異常以及向赤道輻合的經向風應力異常，東風應力異常及向兩極輻散的經向風應力異常與elnino消亡對應。The distribution of lrgr summer mean rainfall was determined by the obstructing effect and two stronger ascending airflow that come from bengal bay and south sea and converge around corresponding windward slopes ; the general circulation distribution in meridional section is equal, which showed the passing - effect of lrgr
縱向嶺谷區多年平均夏季降水空間分佈主要由縱向嶺谷的「阻隔」效應，以及夏季從孟加拉灣來的氣流和從南海來的氣流在相應迎風坡面輻合，形成兩支較強的上升氣流所致；而縱向剖面大氣環流的變化則較為均勻，顯示了縱向嶺谷的「通道」效應。But it will affect the airflow organization with the cooled airflow drops. also, it studies the impact of solar radiation on displacement ventilation and cooled ceiling system. horizontal warm areas lowers the height of thermocline and is unfavorable to displacement ventilation system ; vertical hot surfaces will destroy the thermal stratification
水平熱表面的存在，會使系統的溫躍層高度降低，對置換通風系統會有負面影響，為了減小水平熱表面的影響，對于地板材料應該選擇對長波輻射吸收較低的物質;垂直局部熱表面的存在會破壞置換通風系統溫度分層的特性，使垂直方向溫度變化減小。The results show that there are two centers of occurrence of llsw respectively in dong bei and jiang nan ; the regional torrential rain over the yangtze river basin is closely associated with llsw during the major periods of heavy rainfall ; the diurnal variation of the number of occurrence in the middle and low reaches of the yangtze river is the strongest in china there are some significant differences between llj and nallsw in positive season, spatial variation, diurnal variation and field of pressure. by the way, the important effect of inertial stability on heavy rainfall with both low level south - westerly jet and high level northerly strong flow is analyzed theoretically. the results show that the existence of the maximum of inertial stability in the left font of the low level jet is favor of the accumulation of the moist thermal energy, and conditional symmetric instability or convective instability can be expected in this region
另外，慣性穩定性的作用以往不受重視，本文通過對西南低空急流左前方和高空偏北大風軸右後方的慣性穩定性和對稱穩定性的理論分析和實例計算，表明慣性穩定性在伴有高低空急流的暴雨中有重要意義，揭示了梅雨暴雨的一種新的高低空急流耦合機制：低空急流左前方慣性穩定度大值區的存在，有利於低層濕熱能量的積累，使低層傾斜對流的不穩定發展更多期望于條件性對稱不穩定或對流不穩定；高空偏北大風軸（西風急流）的存在，是其右後方（右側）出現對稱不穩定的有利條件，高空相對容易出現干對稱不穩定；慣性穩定性的作用，使低層的傾斜對流更偏向於垂直方向，有利於對流發展，使高層的傾斜對流更偏向於水平方向，有利於高層輻散。There are two parts in this paper : firstly, a set of single doppler velocity models are presented for typical ambient windfields that include those of being uniform horizontally, macroscale convergence and divergence, which overlap warm and cold advection. which are marked by different signatures in the single doppler velocity field. the models proposed can help users identify useful information from the dopple velocity patterns
