高雲-
As for a space - based cloud radar, the change of the radar reflectivity n and the change of attenuation rate along with the cloud liquid water content have been compared between 37 ghz and 94ghz. the transmittance t of single level cloud for different heights and liquid water content has also been calculated at 2 frequencies. by defining a = n tr, which combines both effects of radar reflectivity and transmittance, we have examined the values of a at 37ghz and 94ghz for high, middle and low cloud liquid water contents
對空間測雲雷達，討論了37ghz和94ghz這兩個頻率的雷達反射率和衰減系數隨雲液水含量的變化；計算了不同高度的單層雲在不同頻率，不同含水量情況下的雲層透過率_ ；定義a = _來綜合考慮雷達反射率和透過率對空間測雲雷達回波的影響，分析比較了雲含水量高、中、低時37ghz和94ghz的a值大小。 -
The main relative systems of heavy - hard rainfall in northeast plateau are western pacific subtropical high, south asia high, low latitude systems, upper level jet ( ulj ), low level greater wind speed axes, westerly trough and plateau trough, low level vortex, cold frontal, occluded front in qinghai lake, mesoscale low pressure, heat low - pressure in qinghai, shear line and convergence line, mesoscale cloud cluster, etc. the west subsidiary model of south asia high is the main circulation type of heavy - hard rainfall in this area
3 、西太平洋副高、南亞高壓、低緯系統、高空急流、低空大風速軸；西風槽和高原槽、低渦、冷鋒、青海湖錮囚鋒以及中尺度低壓、青海熱低壓、切變線與輻合線、中尺度雲團等系統是高原東北部地區大到暴雨的主要相關系統。 100hpa上的南亞高壓中心強度加強，位置東西擺動預示高原地區將有降水產生，中心強度減弱，降水過程結束。南亞高壓西部副型是高原東北部地區大到暴雨的主要流型。 -
The one is brought by meeting and overlapping of mixed and high level trough moving eastward cloud systems whose echo depth is about 12 km, and the horizontal distance is within 10 ~ 20km and the intensity is up to about 50dbz
混合雲團與東移的高空槽雲系相遇並疊置的大到暴雨過程，鑲嵌于回波中的對流單體是造成強降水的直接系統，其尺度只有10 ~ 20km 。 -
These mean images reveal not only the synoptic cloud systems but also the mesoscale convective cloud cluster. the long - term high water level of mid - yangtze river and the frequent flood peak of the upper yangtze river from the middle of june to the middle of august in 1998 was caused by the high frequent activity of convection
旬月和季平均雲圖表明，長江上游從6月中旬開始到8月中旬長達兩個多月對流的頻繁發生是「 98洪水」長江上游洪峰多，中游高水位維持時間長的重要原因。 -
The result show that the surface net radiative fluxes is linear to the solar radiation of top of atmosphere, the infrared radiative fluxes emitted by earth - atmosphere system and the solar radiative fluxes reflected by earth - atmosphere system. the correlation coefficient keep on a high level. and in this paper we develop the regression equations ( for all days and for cloud days ) to estimate the surface net radiation on an hour scale
結果表明08 - 17時地表凈輻射通量與大氣頂太陽輻射、地氣系統發射紅外輻射和地氣系統反射的太陽輻射線性相關，相關系數維持在一個較高值，並建立了用衛星資料反演08 - 17時各時刻地表凈輻射通量的估算模式（適用於各種天氣情況） 。
