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。In this axial turbine, steam always flows along the axis of rotated axis, thus, all blades extend with the radiation shape along the axis outward
在這種軸流式渦輪機中，蒸汽總是沿主軸的旋轉軸流動的，因此，葉片由主軸向外呈輻射狀展開。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。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
本論文包括兩個部分：第一篇通過對典型風場的單多普勒天氣雷達徑向速度圖象進行模擬，典型風場包括水平均勻一致的風場、非均勻水平風場的大尺度運動的輻合輻散風場以及大尺度運動的輻合輻散風場與冷暖平流的迭加等。The finite element method ( fe '. i ) is adopted to analyze the effects of the numbers of coil turns, current intensity and current frequency upon the rate of joule heat generation in details. the thermo - radiation analytical countermeasures of various types are adopted to carry out the numerical analysis of the effects of the crucible with different shapes and sizes and the blind holes with different depths opened in the tops of crucibles as well as coil positions upon the thermal field distribution whereby solving the main problem of field the thermo - field design of the induction - heating sic crystal growth system. a new combination idea of the thermo - field design obtained by means of the united design of the thermo - insulator and blind holes has been presented
採用有限元分析方法對線圈匝數、電流強度、電流頻率等對焦耳熱產生速率的影響進行了詳細的分析討論；採用不同的熱輻射分析策略，對不同坩堝形狀、坩堝頂部開設不同深度的盲孔以及線圈的位置等對熱場分佈的影響進行了數值分析，解決了感應加熱碳化硅晶體生長系統熱場設計的主要問題，提出了通過絕熱層與盲孔的聯合設計獲得所需熱場設計的思路，給出了根據軸向溫度梯度的波動對線圈位置實行動態調節以控制熱場的理論依據。Single - layer model is convenient to apply but the unclear relationship between radiative and aerodynamic temperatures is still a bottleneck in this field. a new method was developed to derive reliable surface heat fluxes from radiative temperature viewed from arbitrary zenith angle. aerodynamic and radiative temperatures are connected through a so - called optimum component fraction ( ocf ) parameter - the fraction of vegetation in the field of view when the two temperatures are equivalent in oblique viewing
該方法利用表面熱輻射方向性和顯熱通量都是源於土壤和植被溫度的貢獻這一共同點，發現在一定傾斜角度的觀測下，視場中植被與土壤的比例可以較好地反映植被和土壤與大氣進行湍流熱交換的貢獻率，所以稱該方法為最佳組分面積比法，用最佳組分面積比可以將任意角度下觀測到的輻射溫度訂正為空氣動力學溫度，經過地面和遙感數據驗證表明，用該方法計算的通量精度高於普通的單層模型。A transverse secondary circulation is produced by the coupling of high and low jets, while the sinking branch of the secondary circulation providing the dynamic conditions for the dry intrusion air. during the period of the heavy rain process, dry intrusion descends southward along the intense constant potential temperature lines, which promotes the lower cyclone. in addition, the pouring of upper - level dry air not only decreases ground temperature behind the front but also increases surface pressure and velocity
由於高、低空急流耦合，在高空急流中心左側產生的下沉運動和高空急流中心右側、低空急流左側產生的上升運動在鋒面上形成一次級環流，次級環流的下沉支運動為對流層高層干空氣和高位渦的下傳提供了動力條件；進一步研究發現，干侵入沿相當位溫密集帶向南向下伸展，引起對流層低層氣旋性渦度的發展；此外，高層乾冷空氣向下注入，導致地面溫度降低、氣壓升高、風速加大、低層輻合增強、上升速度加大，從而促進了新的對流運動，引起降水增強。Climatic mean map, it is further confirmed that it s a good approach to retrieve the equatorial zonal circulation by using the ir indicate ascending branch and wv indicate descending branch channels. the definition of the index of zonal circulation with the olr and fwv are presented and the 17 years mean annual and seasonal equatorial circulation are drawn. the climatic characteristics of the equatorial zonal circulation are analyzed in detail. consequently the fore results of the other observation are corrected
