资源简介

摘要: 利用地基Ka波段云雷达和无线电探空仪数据进行云边界识别和对比分析研究。结果表明,8毫米波云雷达探测的云底高度比无线电探空仪观测偏低约300 m,大多数情况下二者识别的云底高度接近;而判定的云顶高度偏差较大。雷达与探空云底高度判别偏差较大时,在云下常存在大气“干层”,此时雷达探测更为灵敏;探空仪水平漂移及其湿度传感器的探测误差随高度增加是造成两者偏差的主要原因。通过计算和对比雷达反射率的时空变化率,给出了云雷达确定云底和云顶高度的一个可信度判据。 关键词: 云雷达;  探空仪;  云高度;  识别算法;  可信度     Abstract: The observation data obtained by a Ka-band cloud radar and radiosondes during July to August 2013,in Inner Mongolia were used to detect the cloud boundary.The results show that the Cloud Base Height(CBH) determined by the cloud radar is about 300 m lower than that from the radiosonde,and the CBHs from two equipments are close in most cases;however,the heights of cloud top are largely different.The analysis of the case with larger CBH deviation indicates that the radar detection is more sensitive than the radiosonde because of the presence of an atmosphere "dry layer" under the cloud base;The main causes of the deviation are the horizontal drift of the radiosonde and the humidity sensor error that increases with increasing height.By calculating and comparing the variation rate of cloud reflectivity,a credibility criterion is given for cloud radar detection of the height of cloud base and cloud top.
