Abstract
The disclosure relates to a method and device for determining descriptive information of a precipitation trend and a readable storage medium. The method includes acquiring precipitation data in a preset time period; acquiring precipitation intensities at a plurality of precipitation moments in the preset time period from the precipitation data, the plurality of precipitation moments being obtained by dividing the preset time period according to a preset strategy; selecting at least one critical precipitation moment from the plurality of precipitation moments based on the precipitation intensities at the plurality of precipitation moments, the at least one critical precipitation moment referring to a precipitation moment playing a critical role in the descriptive information of the precipitation trend in the preset time period; determining timeliness corresponding to the at least one critical precipitation moment; and determining the descriptive information of the precipitation trend in the preset time period based on the timeliness and a precipitation intensity corresponding to the at least one critical precipitation moment.
