Abstract

The embodiment of the invention provides a rainfall data estimation method and device, equipment and a storage medium. The method comprises the following steps: acquiring sample data of each ground rainfall station in a target area, and dividing all the ground rainfall stations into a plurality of station sets based on a step-by-step clustering analysis algorithm; for each station set, calculatinga correlation coefficient between each type of geographic parameters included in the station set and precipitation data of an area where the station set is located; taking a geographic parameter corresponding to the first correlation coefficient as a covariable, and processing the station precipitation data of each ground precipitation station in the station set by adopting a spatial interpolation algorithm to obtain first estimated precipitation data of an area where the station set is located; wherein the first correlation coefficient is a correlation coefficient greater than a preset threshold value in correlation coefficients corresponding to various geographic parameters in an area where the station set is located. The first estimated rainfall data estimated by the rainfall data estimation method is high in interpolation precision, and the precision of rainfall spatial distribution data is improved.

Description

technical field [0001] The present application relates to the technical field of meteorological information, in particular to a method, device, equipment and storage medium for estimating precipitation data. Background technique [0002] Precipitation is a central component of the global water and energy cycle. As a key input of the watershed hydrological system, the spatial distribution of precipitation directly affects the temporal and spatial evolution of various elements of the regional hydrological cycle (such as runoff, soil water, evapotranspiration, etc.); quantitatively estimating the spatial distribution of precipitation is an important issue in the field of hydrometeorological research. Hot Issues. [0003] Surface rainfall stations are the main way to collect traditional precipitation data. Observation of precipitation by ground rainfall stations has the following three advantages: (1) it is the only way to directly measure precipitation; (2) it has a long obse...
