A Study of Regional Rainfall Estimation by Using Radar and Rain-Gauge (Ⅰ) : Proposal of Mode Integration Method
Weather radar estimation for regional rainfall is an important field of its application,and to improve the accuracy and stability of regional precipitation estimation by means of radar data is an important task for meteorological radar service.The theoretical basis and development of ensemble forecasting are reviewed,and the methods and products are summarized.Previously used eight radar estimation methods for regional precipitation are systematically analyzed from the aspect of basic principles and characteristics.On this basis,the applicability of ensemble forecast theory in the field of radar estimates for regional precipitation is further discussed.A conceptual model and two methods for integrated regional precipitation estimation are proposed,which provides theoretical support for further applied research.
