We can see many performances in washington park , chinatown , psu campus , pioneer square , and farmer market 在華盛頓公園、中國城、大學(xué)校園,先鋒廣場、農(nóng)貿(mào)市場,我們都可以看見各種群眾性的演出。
By using the psu / ncar mm5 model , we made a numerical simulation about the severe sand - dust storm that occured in the north china on 20march in 2002 20 ”強(qiáng)沙塵暴天氣過程進(jìn)行了數(shù)值模擬,并利用模式輸出的各物理量對沙塵暴進(jìn)行診斷分析,得出了華北地區(qū)沙塵暴的形成、發(fā)展機(jī)制。
In this paper , we use psu / ncar mm5 model to make a research about an explosive cyclone that occurred in western pacific between december 19 and 21 in 1981 , we have a good simulation about the evolution of the real weather process 本文以1981年12月19日? 21日發(fā)生在西太平洋上的一次爆發(fā)性氣旋為例,用psu ncarmm5模式對該天氣過程進(jìn)行了數(shù)值模擬試驗,比較好地模擬出了此次天氣過程的演變情況。
Adopting high resolution nested grid project and proper physical parameter , a mei - yu heavy rain process during eight july 22 , 2002 and eight july 23 , 2002 and the meso - b - scale systems alongwith it , were simulated by use of psu / ncar meso - scale nonstatic numerical forecast model mm5 in this paper . the simulation result describes successfully the spatial and temporal distribution of this rain process and the developing course of the concomitant meso - ? - scale systems 本文利用psu ncar的中尺度非靜力數(shù)值預(yù)報模式mm5 ,采用高分辨率套網(wǎng)格方案和適當(dāng)?shù)奈锢磉^程,對2002年7月22日08時到23日08時的一次強(qiáng)梅雨暴雨過程和伴隨的中-尺度系統(tǒng)進(jìn)行了數(shù)值模擬,結(jié)果很好地描述了本次暴雨降水的時空分布及相伴隨的中-尺度系統(tǒng)的發(fā)生發(fā)展過程。
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(shù)在psu / ncarmm5中加入了理想熱帶氣旋初始渦旋,在f -平面和無環(huán)境流場的理想情況下,設(shè)計了兩組靜態(tài)和動態(tài)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(guī)律和分布特征,特別研究了邊界層中熱帶氣旋中心區(qū)域風(fēng)場的垂直細(xì)致結(jié)構(gòu),并初步分析了其物理機(jī)制。
The sacvgb gene was then cloned into e . coli - - b . sublilis shuttle vector psugv4 and a recombinant plasmid named psu - sacvgb was constructed . after transformation with b . sublilis wb600 , the transformants successfully produced vhb intracellularly . the influence of vhb on b . subtilis is under investigation 將sacvgb基因克隆到大腸桿菌-枯草桿菌穿梭載體psugv4中,獲得重組表達(dá)質(zhì)粒psu - sacvgb ,然后轉(zhuǎn)化枯草桿菌wb600 ,轉(zhuǎn)化子經(jīng)2蔗糖誘導(dǎo),該基因在枯草桿菌中表達(dá)。
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(qū)域數(shù)值天氣預(yù)報系統(tǒng)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(chǔ),與國家氣象中心t213模式輸出場資料連接,并應(yīng)用最臨近常規(guī)高空、地面觀測資料做初始場及參數(shù)修訂,在銀河機(jī)群服務(wù)器系統(tǒng)yh / cs16并行運(yùn)算環(huán)境下運(yùn)行的中尺度數(shù)值模式。
