在裸地下墊面時,晴天潛熱佔到凈輻射的60 ,顯熱交換只佔到19 ,在陰天凈輻射同樣主要消耗于土壤蒸發,與晴天不同的是在陰天土壤熱通量積分值小於零,表明土壤在向外釋放熱量;平均狀況下,潛熱、顯熱和土壤熱通分別佔到凈輻射的67 、 21和6 。The paper uses the surface radiation observations from 08 to 17 o ' clock and the visible, infrared digital cloud picture from gms4 at the same time over beijing, tianjin, jinan, taiyuan, hefei, nanjing, shanghai area in june and july 1994

結果表明:在中高層暖性高壓脊及地面變性冷高壓穩定維持的大尺度背景條件下,地表凈輻射引起的近地層冷卻是大霧過程的觸發和加強機制;中低空下沉氣流的存在有助於近地層的弱風條件和穩定層結的建立;低層暖平流的輸入和邊界層的淺層抬升是大霧長時間持續的原因;伴隨冷空氣南下的偏北大風是驅使大霧消散的動力因子。( 3 ) compared with bare soil, income of net radiation declined, apparent heat weakened and latent heat exchange were almost disappeared on the soil surface with film
( 3 )薄膜覆蓋于土壤表面后,與未覆蓋的土壤相比,地表凈輻射r _ n收入下降,顯熱交換p減弱,潛熱交換le趨于零。Roughly acquire optical depth of clear sky and clouds from radiation station data and routine meteorological data of land surface, and the study the relationship between clouds " physical character and radiation. obtain the relationship between surface and near - ground atmosphere, and then according to this estimate surface albedo and surface net. by analyzing the relationship between satellite visible spectra, infrared spectra, and water vapor spectra values and radiation, by means of radiation transfer theory, analyze and deducethe relationship between clouds and radiation, and establish relationships between satellite value and global radiation and net
通過衛星雲圖的計數值來判斷雲對輻射的作用,以此建立起它們之間的關系;利用地面觀測資料和常規資料來粗略求取晴空大氣和雲光學厚度,進而研究雲的物理屬性與輻射關系;簡單的獲取地表與近地面大氣之間的輻射關系,以此估算地表的反照率,和地表的凈輻射;分析了衛星可見光、紅外及水汽雲圖計數值和地面輻射之間關系,利用輻射傳輸公式來推倒和分析雲對輻射的關系,試圖建立起衛星測值與地表總輻射和凈輻射之間的關系,並將晴空和有雲的個例分開,分別建立並選出最佳模式,以此來估算地表的凈輻射和總輻射。The regression equation to estimate the cloud shortwave radiative forcing was established, the result can be used to estimate the cloud shortwave radiation forcing, thus remedying the shortage of radiation data. the surface global radiative flux which occurs for clear skies was computed by using modtran3 model and sounding data and that which actually occurs with cloudiness was from the routine data
利用中解析度輻射計算模式modtran3和站點的探空資料以及地面資料,計算出無雲情況下的地面總輻射,再與實際情況下的實測地面總輻射結合得出雲對太陽輻射的強迫,分析了短波雲輻射強迫和實測地面凈輻射的關系。First, under the given boundary condition and reasonable simplified condition, this paper develops radiation transmitting equations in atmosphere applied in infrared waveband and visual light waveband from common equation of radiation transmitting. then, the formula between observation of satellite and net surface radiation is established according to the developed equations, from which it is found that net surface radiation is relative to sun zenith, land surface and cloud albedo, etc. at last, by using data of satellite visual light ( vis ), infrared 1 ( ir1 ), infrared 2 ( ir2 ) and water vapor ( ir3 ) channel, sun zenith and net surface radiation, a regression formula is built
