| 摘 要： | MF雷达是中层大气风场及低电离层电子密度观测的重要手段.简要介绍了新建昆明MF雷达设备的工作原理、结构及工作模式,并对观测结果进行初步分析.对2009年1月观测数据的分析表明,该月纬向风场最大可达80 m/s,经向风场则较小,一般不超过40 m/s,且二者均呈现一定波动性.相应的LS谱及谐波拟合分析表明,周日潮汐是80～100 km高度大气风场的主要扰动成分,其振幅随高度改变,相位向下传播,且周日潮汐经向分量相位超前于纬向分量相位.此外,分析了MF雷达白天的电子密度观测结果,并与IRI2000进行比较,发现两者在变化趋势上有非常好的一致性,但雷达观测结果小于IRI2000给出的参考值.

| Abstract: | MF radar is an important instrument for measuring the wind field of the mesosphere and electron density of the lower ionosphere.The principle,configuration and working mode of a new MF radar in Kunming are presented firstly.Then,its observation data are preliminary analysed. The observation in January 2009 shows the certain fluctuation character of the horizontal wind with the largest zonal velocity of 80m/s and meridional velocity of 40m/s.The data in this month are studied by using Lomb-Scargle periodogra... |
