The invention discloses a high-precision grid rainfall storage and overlay analysis calculation method and device, and the method comprises the steps: framing a provincial region needing to be calculated through a rectangular boundary, carrying out the rasterization division, obtaining a high-precision grid, endowing each grid with a unique number, and carrying out the storage and overlay analysis calculation based on the monitored rainfall data of a local hydrological bureau. Obtaining the rainfall of each grid through an interpolation algorithm; and based on the grid number and the rainfall capacity of the corresponding grid, carrying out time superposition calculation on the rainfall capacity of the grid to obtain the total rainfall capacity of the rainfall cycle. According to the method, a finer-grained division standard is adopted, a rainfall statistical chart of an ultra-large area can be presented macroscopically, a rainfall statistical chart of a specified rainfall period of any ...
