We can use the mm5 model in definite time, definite area weather forecasting. we conclude that : : the moving route of this necw in its developing progress was direct - south along latitude, the cold air is rough, and just this made the rough vertical velocity ; the necw southern moving and conflicting with the west pacification sub - tropical high makes rough jet steam. the plenty south - west warm and wet air made by the jet stream gave the rainstorm demanded vapor ;. the rough vertical velocity by jet stream is a main reason in this rainstorm ; the mm5 model uses four - direction analysis data as its input, this avoids some errors occurred in observe and transfer, thus made the result more useful
綜合分析認為: ( 1 ) 、這次冷渦在其發生發展過程中,其移動路徑是沿經圈直線南壓,攜帶的冷空氣勢力較強,形成槽后較強的垂直運動; ( 2 ) 、西太平洋副熱帶高壓偏北位置與東北冷渦南壓形成的急流軸,把源源不斷的西南
暖濕氣流輸送到遼西地區,也就是急流軸的左前方位置,為這次暴
雨的產生提供了充足的水汽來源; ( 3 ) 、低空急流不但為暴
雨輸送水汽,其造成的較強的垂直環流也是產生強降水的一個主要原因; ( 4 ) 、 mm5模式以四維同化資料作為初始場,最大限度地避免了觀測誤差可能造成的積分不穩定,提高了模擬結果的參考價值。
But it was scarcely professional etiquette so, though it was a warm pleasant sort of a night now yet wonderfully cool for the season considering, for sunshine after storm. . and he did feel a kind of need there and then to follow suit like a kind of inward voice and satisfy a possible need by moving a motion
但是作為一個文化人,這會兒離座簡直不符合禮節,今天晚上舒適
暖和,然而就季節而論,又十分涼爽,因為一場暴
雨之後,陽光這當兒他感到一種需求,好像有個內在的聲音,要他學著樣兒出去走動走動,滿足一下可能的慾望。
There were soft winds and fierce winds. and then there was the dreaded sirocco, the warm wind that blew in from the sahara.
有微風和狂風,此外還有可怕的非洲悶熱帶
雨的風,從撒哈拉大沙漠吹來的

There is a vaporizing layer below 0 layer and it is far thick, which may be one of the important reasons of small precipitation on ground ; in the paper the cloud and the rain drop size distribution in warm layer of stratiform cloud are calculated and analyzed. it is found that n ( d ) = n0dnexp ( - a d ) can express the size distributions of little cloud drops, big cloud drops and rain drops. the observational and calculated results are well matched
在零度層以下蒸發層的存在,且比較深厚,應是導致地面
雨強較小的重要因素之一;本文對
暖層的雲滴譜和
雨滴譜進行了計算,對小雲滴、大雲滴和
雨滴分佈可以用同一種形式的分佈密度函數多階函數n ( d ) = n _ 0d ~ nexp ( - d )來表示。
The magnitude of these variables increased approximately ten times. it helped the rapid releasing of instability energy. the interaction of high - level and low - level mesoscale system leads to the rainstorm. the vertical cross section analysis of potential temperature tells us that rainstorm take place in the warm - moist and instability area. usually locate in the very stiff moist isentropes and it can lead to the development of vortex
通過對相當位溫的垂直剖面分析,可知兩場暴
雨的中低層都為
暖濕不穩定區,
暖濕不穩定區上部冷空氣明顯擴散,暴
雨產生在
暖濕對流不穩定區內,通常產生在_ e陡峭和密集區中, _ e陡峭和密集區有利於渦旋發展。
For losing athletes, there are no excuses. unlike chief executives, they cannot blame ad - verse market conditions, currency movements, sars, the iraq war, the wet summer or the mild winter
運動員一旦失敗,是沒有藉口可講的。他們不同於執行長們,不能去歸咎不利的市場形勢、匯率變動、 sars 、伊戰、夏季多

( 2 ) from the viewpoint of growth, it has powerful branching ability. it is suitable to be transplanted in warm seasons such as spring and autumn, or in small rainfull period, and generally it is optimal in october and april. it is also suitable in topography and soil with good discharge capacity, and soil humidity should remain from 15 % to 70 %
( 2 )在生長發育上,迷迭香具有較大的分枝能力,適宜選擇春季和秋季溫

雨量不多的時期扦插,一般在10月和4月最佳,要求排水良好的地勢和土壤,土壤濕度應保持在15 - 70之間。
Warm rains are the forerunners of spring
暖雨是春天來臨的前兆。
And with warm rains melting snow or drenching already saturated ground, the risk of extreme floods will rise dramatically
並且隨著
暖雨融化冰雪或者下到水量已飽和的地面,大洪水泛濫的危險將急劇增長。
