WMO第八届阳江国际探空比对辅助遥感综合试验 总被引：1，自引：0，他引：1
第八届阳江国际探空比对辅助遥感综合试验为分析探空仪系统在高空出入云的温湿特性,评估高层云红外辐射对温度传感器的影响以及湿度传感器的系统偏差提供有力帮助。通过试验,还评估了国产X波段双偏振雷达与毫米波云雷达的优缺点和性能差异,以及国产多普勒激光雷达、微脉冲激光雷达的探测性能和应用能力,在改进微波辐射计温湿反演算法、X波段偏振雷达参数的云中粒子相态模糊逻辑识别算法,以及多普勒天气雷达风场反演、云分类算法、高空业务测风算法等方面开展广泛研究并取得一定进展。试验还利用先进的各类遥感设备对阳江热带地区的云、局地对流以及海陆风系统的结构进行了观测和分析,取得了较好的研究结果。 相似文献

Observations made with the co-located Rayleigh lidar and MST radar systems at Aberystwyth (52.4°N, 4.1°W) in Wales and radiosondes from Valentia (51.9°N, 10.2°W) in Eire are used to investigate the changes in the vertical propagation of gravity waves during periods of 4 days in June 1995 and February 1993. In each month, the lidar observations show that the wave activity in the upper stratosphere and lower mesosphere changes between two pairs of days. The radar and radiosonde measurements indicate that mountain waves make no contribution to the changes in intensity. Instead, the changes seem to arise largely from the presence or absence of long-period waves with vertical wavelengths near 8 and 10 km in June and February, respectively. The influence of such waves on the vertical wavenumber spectra is examined and related to the evidence for convective instabilities provided by the temperature profiles. 相似文献

This paper describes an intercomparison between the Väisälä, VIZ and Swiss (used at upper-air station 06610) radiosondes. The field experiment was supported by a series of carefully implemented laboratory tests. The results show that the temperature sensor data from the SMI and VIZ sondes both require additional radiation compensation for daylight ascents whilst the Swiss sonde's pressure sensor has particularly large errors in the 200–100 mb region. New correction parameters have been determined for the SMI and VIZ sondes and these have now been built into the systems' software. 相似文献
