積雲參數化 的英文怎麼說
中文拼音 [jīyúnshēnshǔhuà]
積雲參數化
英文
cumulus parameterization-
( 5 ) parameterization of infrared satellite cloud imagery and its application in rainfall predication obvious correlation exist between the probability of rain and parameterization estimate such as average brightness temperature ( tb ), brightness temperature variance ( f ), equivalent cloudage ( cn ), brightness temperature area index ( al - the first a5 - the fifth grade, a6 - the sixth grade )
（ 5 ）衛星雲圖參數化及在降雨預測中的應用紅外衛星雲圖參數化估計值，與局地降雨過程的發生、發展具有較為密切的關系。相關較密切的參數有平均亮溫、亮溫方差、等效雲量、亮溫面積指數（ 1級、 5級、 6級） 。The neogene is a key stage of terrestrial environmental evolution in yunnan. three stratigraphic sections including luhe ( late miocene ), yangyi and longling ( late pliocene ) were selected to reconstruct vertical landscape of paleovegetation in these areas, based on palynological data. according to principle of the coexistence approach, seven quantitative paleoclimatic parameters of each deposit area were obtained by using meteorological data ( 1951 - 1980 ) of the distribution area of extant taxa found each palynoflora in china
晚第三紀是雲南地區環境演變過程中的關鍵地質歷史時段，本論文以晚第三紀晚中新世（呂合） 、晚上新世（羊邑和龍陵）地層中的孢粉為研究對象，結合同層位大化石植物證據，參照現代植被，恢復了雲南三個化石出產地區的古植被垂直分佈景觀，並定性地描述了古氣候；同時運用共存分析方法（ theco - existenceapproach ）定量化地重建了三個地區的古氣候參數值；初步推測了沉積地可能的古海拔。The horizontal scalelength of model variables ( u. v. t, p and q ) is closely related to the average time of nmc technique and convective parameteric scheme of mm5 which affect the 12h and 24h outputs of mm5 integration
、 、 、 t 、 p和q ）對應的誤差水平尺度與nmc方法中預報誤差的平均時間長度和模式提供1zh和24h預報所選用的積雲參數化方案有直接的關系。Mm5 has a ability of simulating zwd on the whole with a bias larger than zhd ' s, which manipulates the bias of ztd simulation. the increase of mm5 resolution can improve the ability of simulating and depicting zhd, zwd and pw distribution. kf, bm and grell parametric schemes have a close ability of simulating pw at the beginning of 10 - 11h integration of mm5 model, and then the prediction bias of pw increases obviously after 20 - 21h integration
在mm5模式24h積分的前10 11h ，選用kf 、 bm和grell三種積雲參數化方案模式對可降水量的預報偏差基本接近，對可降水量具有較好的預報能力，其後三種積雲參數化方案對可降水量的預報偏差差異增大，模式積分至20 21h后對可降水量的預報能力明顯減小。The results also show that the precipitation forecast of the system is very sensitive to cumulus parameterization scheme, planet boundary layer ( pbl ) scheme and radiation scheme. for smaller meshes, the grell cumulus parameterization scheme is better than the other three cumulus parameterization schemes that are also tested in the experiments
數值模擬試驗結果還顯示，模擬降水預報對積雲參數化方案、邊界層參數化方案、輻射參數化方案等比較敏感；在網格比較小時， grell積雲參數化方案優于本文試驗的另外三種積雲參數化方案。分享友人
