synoptic situation 中文意思是什麼
synoptic situation
解釋
夫氣形勢-
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。 -
A method of forecasting the heavy rainfall in the miyun reservoir basin is developed, according to the synoptic situation during the heavy rainfall, by means of the interpretation and application of nwf outputs, and the local observations
摘要為了探索密雲水庫流域性暴雨的預報，著眼于影響暴雨的天氣系統，從數值預報的解釋應用入手，試驗製作了密雲水庫流域性暴雨預報方法。 -
Please note that the observations may change from time to time, as well as from place to place, for reasons ranging from changes in the synoptic situation to short - term or local changes due to the complex coastal and mountainous terrain in hong kong
請注意有關的觀測可能隨時間和地點的改變而有所不同。這是可能由於大范圍天氣情況改變，又或者是受到本地復雜海岸及山嶺地形影向而出現之短期或局部轉變。 -
A state high - tech enterprise - kunming north infrared technology co, ltd. ( knit ) which was established three years ago is regarded as a studied object. part three introduces the synoptic situation of knit and its former cost control system, and evaluates its deficiencies. this will paves the way to redesign the cost control - system of knit
為了實現abcm由理論到實踐的進一步深化，在第三、四部分中，作者選擇了一家成立僅兩三年的高新技術企業? ?紅外公司作為研究對象，首先介紹了該公司的基本情況以及公司原有的成本控制系統，並就該系統存在的主要問題與缺陷進行了分析與評價。
