根据中国海南富克(19.3°N,109.1°E)三点GPS观测系统2007年3月至11月的观测数据,利用互相关方法分析了三站闪烁信号的时间延迟,得出了不规则体纬向漂移的基本特征.在中国海南地区,闪烁主要发生在春秋季节,夜间不规则体的纬向漂移速度以东向为主,大小在50～150 m/s之间;平均东向漂移速度随时间呈下降趋势.另外,在闪烁刚发生时,不规则体纬向速度起伏较大,这可能与不规则体的随机起伏以及等离子体泡产生时垂直速度较大有关.中国海南地区不规则体纬向漂移速度的这些基本特征与低纬其他地区的测量结果较为一致.
According to the observational data from March to November 2007, the three-point GPS observation system of 1948 ° F (19.3 ° N, 109.1 ° E) in Hainan, China, the time delay of three blinking signals was analyzed by the cross-correlation method. The irregularities In Hainan, China, the flicker occurs mainly in spring and autumn. The latitudinal drift velocity of the irregular bodies is mainly eastward with a size of 50-150 m / s in the night. The average eastward drift velocity With the decreasing trend over time.Furthermore, at the beginning of the flicker, the velocity fluctuation in the irregular body and latitude is larger, which may be related to the random fluctuation of the irregular body and the large vertical velocity when the plasma bubble is generated. These basic characteristics of the latitudinal drift velocity are in good agreement with those measured in other parts of the low latitudes.
