中文拼音 [qíngjiānduōyún]
晴間多雲
英文
sunny period partly cloudy partly bright mild-
It ' s staying cloudy tonight, with a 40 % chance of rain or _ _, and tomorrow it ' s going to start dry with bright spells
今日晚間多雲，降水概率40 % ，有跡象顯示明天開始轉晴Some preliminary conclusions of making better image quality are obtained by observing some effects of climate conditions on quality of solar image during spectral observations. they are : ( 1 ) quality of imaging to be better when the wind stops or weaken suddenly during the wind blows continuously ; ( 2 ) if the wind blows at the whole night and it is fine day in the next morning, then the image quality will be better than before. ( 3 ) the image quality is getting fine in short time after the cloudy. ( 4 ) the good solar image to be formed under the condition of a beginning of fine day after the cloudy or raining days
在多年的太陽光譜觀測中，通過觀察各種天氣條件的變化對光譜儀成像質量的影響，初步總結出使像質優良的幾條規律： 1 ）在連續刮風過程中當風突然停止或減弱的短暫時間內像質明顯變好； 2 ）當夜間通宵有風而次日天氣晴朗時像質變好； 3 ）多雲過后的短暫晴天成像優良； 4 ）接連陰雨幾天後的開始晴天像質較好。With reference to calculation methods of solar radiation within domestic and abroad literature and with the help of our country ' s dem ( with its resolution is 1 km x 1 km ), we build a new model for potential solar radiation calculation combining with pci geomatica ' s platform. in the calculation, hypothesis is that insofar one clear day in more than one year as the biggest value of solar radiation of one day in many years is defined as potential value of daily global solar radiation, we also consider the infection of the slope, aspect and its geometry relations affect on solar radiation. we calculate potential solar radiation which maybe useful for research the distribution of solar energy and build large - scale grid database of our country ' s solar radiation
本研究試圖在借鑒國內外已有的太陽輻射計算方法的基礎上，利用全國的1 ： 100萬數字高程模型數據（ grid大小1km 1km ）為數據源，以pcigeomatica為計算平臺，以全國多年的太陽輻射日觀測數據進行模式驗證，在晴天無雲的理想條件下，根據太陽光線與實際地形間的幾何關系，研究坡度、坡向等地形因子對太陽輻射的影響，探討太陽輻射在復雜地表上的分配規律，力求尋找潛在太陽總輻射合理的計算方法，為研究太陽輻射時空分佈特徵和建立全國尺度的太陽輻射柵格氣象數據庫奠定基礎，為大尺度上的生態學過程研究提供基礎信息。
