Short temporary rainfall weather prediction method and device, electronic equipment and readable medium

Abstract

The invention relates to a short temporary rainfall weather prediction method and device, electronic equipment and a computer readable medium. The method comprises the following steps: respectively generating an observation precipitation probability graph, a satellite precipitation probability graph and a radar precipitation probability graph based on meteorological observation data, a meteorological satellite cloud picture and a radar echo graph; performing longitude and latitude correction on the observation rainfall probability graph, the satellite rainfall probability graph and the radar rainfall probability graph; inputting the corrected observation precipitation probability graph, the corrected satellite precipitation probability graph and the corrected radar precipitation probability graph into a precipitation analysis model to generate a short-term actual precipitation graph; and predicting and / or correcting the short-term rainfall weather based on the short-term actual rainfall map. According to the short temporary rainfall weather prediction method provided by the invention, the short temporary rainfall is predicted in combination with the meteorological data of multiple channels, so that the use range of the socialized meteorological observation data can be expanded, the data source of the short temporary rainfall can be enriched, and the prediction accuracy and precision of the short temporary rainfall are improved.

Description

technical field [0001] The present application relates to the field of meteorological forecasting, and in particular, to a method, device, electronic device, and computer-readable medium for forecasting short-term precipitation weather. Background technique [0002] Precipitation is a phenomenon in which water vapor in the atmosphere condenses and falls to the ground as liquid water or solid water. It usually exists in the form of rain and snow in nature. As a very common weather phenomenon, precipitation generally affects human health. Production and life have a certain impact, so people tend to pay more attention to precipitation weather. The short-term precipitation forecast refers to the prediction of the precipitation in the next 0-12 hours. This kind of forecast is usually more precise in time and space, and can give minute-level and kilometer-level grid point precipitation forecasts. [0003] With the advancement of science and technology and the acceleration of the ...

Problems solved by technology

In addition, geostationary meteorological satellite cloud images can also be used for short-imminent precipitation forecast, but the accuracy rate is lower than that of short-imminent precipitation forecast based on weather radar data, and currently it can only be used for auxiliary forecasting

Meteorological radar data, as the core dependent data of short-term precipitation forecast, usually has the following problems: 1. There are many clutters in radar data (including meteorological clutter and non-meteorological clutter); 2. Echo loss in radar data ( Radar failure, external interference, seasonal factors, meteorological factors, etc.) 3. The radar shutdown period is long (especially in autumn and winter)

All of the above reasons will lead to errors in short-term precipitation forecasts, which will have a certain negative impact on people's production and life, and will generate a large number of artificial weather feedbacks
