摘要:
新一代天气雷达观测模式使用观测的仰角都在0. 5毅以上,而在0. 5毅以下是没有仰角的,这样就导致雷达 估测降水时反射率因子Z 值场的取值精度降低和取值范围缩小,致使雷达估测降水的能力降低,而Z 值场的取值 往往以零度层亮带以下的中低层范围为宜。计算并分析正、负仰角下雷达的最低探测高度,得到雷达在-0. 3毅仰角 的最低探测高度明显低于0毅仰角和0. 5毅仰角,表明采用负仰角探测可以有效的降低最小探测高度;读取VCP11 和 VCP22 两种体扫模式下的雷达仰角数据信息,分析在0. 48毅、0毅以及-0. 31毅仰角下雷达探测降水回波的能力,发现 仰角越低探测到的降水回波越多。
Abstract:
The most elevations of new generation of weather radar observation mode are above 0. 5 毅, and there is no ele- vation under 0. 5 毅, thus causing loss of accuracy and reducingvalues range of radar reflectivityfactor Z during radar rain- fall estimation , decreasing the ability of the radar to estimate precipitation . But the value of Z field is often with zero layer bright band in the middle and lower range is appropriate. This paper calculates and analyses the positive and nega- tive elevation radar detection minimum height, The lowest detection altitude of radar in -0. 3毅elevation was significantly lower than that of 0毅elevation and 0. 5毅elevation, indicating that the negative elevation detection can effectively reduce the height of the minimum detection ;Read the radar elevation data information in the VCP11 and VCP22 scanning mode, the analysis of radar detection of precipitation echoes at 0. 48毅, 0毅and -0. 31 毅elevation, found that the lower the elevation, the more precipitation echo.
