This paper discuss the effect of roughness coefficient on the tropical cyclone landfalling process using a idealized tc model developed from psu / ncar mm5 in the condition of quiescence and f - plane atmosphere. in order to understand the different influences of land and sea surfaces in the tc landfalling process, two kind of experiments had been designed : one for settled tc, the other for movable tc, and each kind consists four tests. the result indicates that the distribution of wind, precipitation, warm core and intensity of tropical cyclone has been changed obviously due to the effect of difference between the land and sea
本文利用bogus技術在psu / ncarmm5中加入了理想熱帶氣旋初始渦旋，在f -平面和無環境流場的理想情況下，設計了兩組靜態和動態試驗，通過控制試驗和不同粗糙度的登陸試驗，分別從空間和時間上探討了理想熱帶氣旋的登陸規律和分佈特徵，特別研究了邊界層中熱帶氣旋中心區域風場的垂直細致結構，並初步分析了其物理機制。 -
Therefore, this article has carried on the following work : 1. designed and made a movable wind erosion tunnel drove by tractor firstly in our country. the wind speed range of the tunnel is from 2 m / s to 28 m / s and the speed can be adjusted continuously
研製了我國第一座使用拖拉機為動力的移動式風蝕風洞，風洞風速為2 28m s ，且連續可調，風洞總長11m ，實驗段長6m ，為無底矩形截面， 1 . 0m高、 0 . 8m寬。 -
So, it is significant from present and long - term benefits to design and make movable wind erosion tunnel, and to apply it as a tool to carry out research on protective cultivation, diminution of soil wind erosion, reduction through conservation tillage
因此，設計和製作移動式風蝕風洞，用風洞作為有力的工具，開展保護性耕作減少土壤風蝕，防治沙塵暴的研究就具有重要的現實意義和長遠意義。為此本文進行了下列工作： 1
