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

利用星载雨量雷达和地面雨量计测得的雨量累积分布预测降雨强度空间相关特征的新方法。将该方法应用于热带降雨测量任务卫星降水雷达获取的资料，估算了日本全国52个气象站附近区域的空间相关特征。结果表明，日本中部和西部的空间相关特征表现出明显的区域依赖性，这与我们对雨气候学的经验认识相一致。

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.
