机载微波辐射计云中含水量的探测

A Column Cloud Liguid Water Content Measured by Airborne Upward-Looking Microware Radiometer

通过对2003年4月18日在延安地区用单波长(0.95 cm)机载微波辐射计探测到的层状云云中液态水含量的分析,结果表明,层状云中的过冷水平均含量为0.0171 g.m-3。分析其变化,发现云中垂直向的液态水存在高值区,这一区有助于人工引晶催化增雨(雪)作业,有利于冰晶的增长,可提高人工催化作业的效果。与机载粒子测量系统(PMS)及地面711数字化雷达的探测结果进行比对,机载微波辐射计和PMS粒子测量系统的探测结果有较好的一致性;并且在垂直区域的探测上比PMS粒子测量系统更具有代表性;与711数字化雷达的探测结果也吻合。

Using a single wavelength（0.95 cm） column cloud liquid water content by Airborne Upward-looking Microwave Radiometer measures the Cloud Liquid Water Content in stratiform clouds（CCLWC） in Yan′an area on April 18,2003.The analyzed results show that the average supper-cooled cloud liquid water content（SCCLWC） is 0.0171 g·m^-2.It was found that it had a high value range on the vertically CLW by analyzing the CLWC had changed in stratiform cloud.Which range was contribute to the operations of precipitation-enhancement,be good for enhancing ice crystal′s,improving effective on operations of catalyze.The Airborne Upward-looking Microware Radiometer is compared to the PMS radar and the 711 numerical radiometer on the ground surface,and its results are shown that the Airborne Upward-looking Microware Radiometer and PMS radar have the same measured;and that the Airborne Upward-looking Microware Radiometer is more topical of the PMS radar by measuring of the vertically range,and testimony tallies with the results of the 711 numerical radiometer on the ground surface.
