| 摘 要： | 利用组网天气雷达格点反射率因子确定登陆台风的中心位置,根据台风的反射率因子表现出对称特征,提出一种简单的定位方法——相关法,该方法具有较高的时间分辨率,能对临近登陆台风连续定位.通过2008年台风“黑格比”与2009年台风“天鹅”两个实例验证了该方法的可行性.结果表明:该方法能较好地确定台风中心位置,以中央气象台给出的...

| Abstract: | According to the symmetrical characteristic of reflectivity factor,a simple method-correlation method is developed based on the reflectivity data from the radar network,which can locate the typhoon eye in the landing period with a high temporal resolution.Two cases,HAGUPIT and GONI,are chosen to examine the proposed algorithm.The results show that the method is better with the absolute error within 15 km compared with that of the Central Meteorological Office of CMA.Another method using radial velocity to l... |
