hydrometeor n.【氣象學】水汽凝結體。

hydrometer

The brightness temperature is highly related to the density of ice hydrometeor . since the convective cloud system is tilted , and the viewing angle is oblique , the area displacement between ice hydrometeor and the surface rainfall rate makes the relation between tb and surface rainfall rate is relatively small 但亮溫和地面降水強度之間的相關性較弱,這是由于該對流系統為傾斜的,冰相粒子和地面降水強度之間存在著位置上的不一致,并且觀測角為傾斜的。

The resulting brightness temperature ( tb ) , hydrometeor structure , and surface rainfall rate relations show that the ice hydrometeor , espatially the ice at the top of the precipitating cloud , decreases the brightness temperature significantly at 85 結果表明,在85 . 5ghz ,冰相水汽凝結體尤其是處于降水云頂部的冰晶粒子由于散射輻射而使得亮溫顯著降低。亮溫與冰相粒子的含量之間有很強的相關性。

A comparison between microphysical characteristics derived from 3 - d cloud model and the results from trmm tmi and pr products show that the selected cloud model gives a relatively realistic hydrometeor profiles 由三維云模式得到的微物理特征與由微波圖像儀tmi和pr產品提供的結果之間的對比表明,所選用的云模式能夠給出相對真實的水汽凝結體廓線。

The hydrometeor information from the cloud model is then used as input into a 3 - d microwave radiation transfer model that calculates the upwelling radiance received by the rediometer aboard the satellite 將云模式模擬的水汽凝結體信息作為三維微波輻射傳輸模式的輸入值,計算星載微波輻射計接受到的上行輻射。
