| 摘 要： | 应用GPS探测的可降水资料PWV对香港地区2013年遭遇的两次台风中水汽变化特征进行对比分析表明,GPS/PWV资料在一定程度上能反映出不同距离台风影响强度，尤其是气压变化。远距离台风，PWV呈现明显的震荡性变化，波动性更强，且震荡程度与降雨强度有很好的对应关系|近距离台风，PWV呈明显的单峰结构变化，增湿过程与台风影响时间及距离存在某种关系，PWV短时间内急升变化幅度能较好地反映降水强度。

| Abstract: | Based on precipitable water vapor(PWV) data from GPS, the water vapor variation characteristics of two typhoons that hit Hong Kong in 2013 are compared. The results show that GPS/PWV data can vary with the intensity of the typhoon, particularly pressure changes. Far from the typhoon, PWV showed significant changes, shocks, stronger volatility. The degree of its shock has a good relationship with rainfall intensity. Close to the typhoon, PWV has a significant change in the structure of a single peak and its humidification process has a relationship with the time and distance from the typhoon. Also a short rapid change of PWV can better reflect rainfall intensity. In summary, GPS/PWV data have some value in monitoring and forecasting typhoons. |
