2 ) from the analysis of the aerodynamic parameters and turbulent flux transfer under different synoptic conditions we achieve the conclusion that on sands raising and sandstorm days turbulent momentum and sensible - heat fluxes are important exchange factors in the boundary layer, with turbulent exchange stronger in sandstorm weather than both on fine and sand raising days. prior to the occurrence of such an event, in particular, the super - adiabatic instability in the near - surface boundary will reinforce sandstorm weather condition. 3 ) atmospheric turbulent diffusion parameters z and y have apparent daily variation
沙塵天氣下以親地殼元素為主的氣溶膠元素濃度均高於背景大氣和浮塵天氣，而且沙塵天氣強度愈強，元素濃度的增加愈顯著；背景大氣、浮塵天氣條件下親地殼元素的濃度一般在10 ~ （ - 1 ） 10 ~ 0 g m ~ 3量級，揚沙、沙塵暴時一般達10 ~ 1 g m ~ 3量級，特強沙塵暴時高達10 ~ 2 g m ~ 3量級。 -
Planetary boundary layer ( pbl ) parameterization is an essential part of numerical weather prediction model. there have been many pbl schemes applied in all kinds of models, such as mm5, wrf and so on
在中尺度模式、大氣環流模式、中長期天氣預報模式及模擬氣候變化的數值模式中，人們已經注意到邊界層所起的作用。 -
The prediction of disastrous space weather is a hot topi c among solar - terrestrial physics and high technological fields. we propose that the future forecasting of the physical conditions that the violent solar disturb ance causes at the earth by propagating in solar wind depends heavily on the num erical method. this paper analyses the existing problems we are facing in the num erical prediction of disastrous disturbance events in solar - terrestrial space, an d then gives some suggestions for future study. for such a purpose, a six step sol ution method is developed to deal with one - dimensional symmetric interplanetary shock dynamics. it should be point out that that initialization of fully self - con sistent 3 - d mhd codes considering the solar - interplanetary - geomagnetic coupled r elations with initial - boundary values at 1r of the global output of solar pl asma and magnetic field using available solar observations is an essential requi rement in space weather operational codes for forecasting purposes
空間災害性天氣的預報是日地物理學界及高科技領域的熱門話題.未來預測太陽劇烈擾動所造成的行星際風暴到達地球空間的狀態勢必藉助于數值方法.淺析了空間災害性擾動事件數值預報存在的問題及未來設想，針對這一目的對一維球對稱問題提出了處理行星際激波的6步求解方法，指出未來空間災害性擾動事件預報模式應是一個基於三維的以真實太陽風為背景自洽建立起來的、以太陽等離子體輸出及磁場全球結構為初邊值、太陽、行星際、地磁因果耦合模式 -
Hunan limited - region numerical weather prediction system is based upon the fifth - generation psu / ncar meso - scale model ( version 3. 4 ), named mm5 which is a non - hydrostatic model. the initial and lateral boundary conditions of the system are generated from the output of the t213 model of the national meteorology center ( nmc ) and the routine observation data of surface and high levels
湖南省有限區域數值天氣預報系統是以psu / ncar的mm5v3 . 4 （第五代中尺度模式版本3 . 4 ）非靜力中尺度模式為基礎，與國家氣象中心t213模式輸出場資料連接，並應用最臨近常規高空、地面觀測資料做初始場及參數修訂，在銀河機群服務器系統yh / cs16并行運算環境下運行的中尺度數值模式。 -
On the basis of frequent field - studies, in the light of the basic theories of ecological design, it tells the benefits and necessity of ecological design for city squares, and demonstrates the basic aims ( aim of function, aim of image, aim of environment ) ; according to the weather and vegetation characteristics of subtropical zone, it tells the cardinal principles ( humality, sustainable development, characteristics distinguishing, integral harmony, public participation ) for the design ; with regard to the architecture enclosing, the space organizing, the boundary effects of city squares, and their size and color, this dissertation also analyzes the space and environment of city squares, and especially discusses the ideas of how to decide the size of a square regarding the problem of building big city squares blindly ; and summarizes the key points of ecological plan and design for the component factors of the space and environment of city squares, and the problem of greening of squares is paid much attention
在多次實地考察的基礎上，本文從生態設計的基本理論出發，指出了城市廣場生態設計的意義及必要性，明確了設汁的基本目標（功能目標、形象目標、環境目標） ；結合亞熱帶區域的地理氣候與植被特徵，提出了亞熱帶區域城市廣場生態設計的基本原則（人性化、可持續發展、突出特色、整體協調、公眾參與） ；分別從尺度、色彩、與周邊建築的圍合、空間組織、邊界效應及內部交通等方面對廣場的空間環境進行了分析，其中針對當今我國廣場建設中「盲目求大」的現象，重點分析了如何把握廣場的尺度問題；總結了廣場的綠化、地面鋪裝、建築小品、水體等空間環境構成要素的生態設計要點，其中著重討論了當今廣場建設中頗為嚴重的綠化問題。
