Study on Spatial Correlation Characteristics of Ground Rainfall by Using Satellite Data and Its Application to Design of Communication Links

利用星载测雨雷达和地面雨量计测雨强度累积分布预报雨强空间相关特征的新方法。通过将这种方法应用于热带降雨测量使命卫星上的降水雷达获得的数据，对日本全国52个气象站周围地区的空间相关特性进行了估计。其结果是，空间相关性特征显示出明确的区域依赖性，在日本中部和西部，与我们的经验知识雨气候学是一致的。

A new method to predict spatial correlation characteristics of rainfall intensity from cumulative distributions of rainfall intensity measured by satellite-borne rain radar and those measured by ground-based rain gauge. By applying this method to the data obtained by the Precipitation Radar aboard the Tropical Rainfall Measuring Mission Satellite, the spatial correlation characteristics are estimated for the areas around 52 meteorological stations all over Japan. As a result, the spatial correlation characteristics are found to show clear regional dependence in central and western Japan that are consistent with our empirical knowledge about rain climatology.
