Problems solved by technology

However, for real-time satellite data, the determination of incipient convective information can only be made half an hour to one hour in advance, and it is impossible to predict the incipient convective information of a longer time (such as short-term 2-6h or short-term 0-72h)
At present, the most effective means of forecasting the weather for more than two hours is the weather forecast numerical model, but there is no forecast of incipient convection information in the weather forecast numerical model, so it is impossible to directly use the numerical model to forecast the incipient convection

Abstract

The invention discloses a method, a device and equipment for determining newborn convection information, and a storage medium. The method comprises the following steps: determining weather forecast data according to acquired satellite data; after a variable required for simulating the infrared brightness temperature value is extracted from the weather forecast data, obtaining the infrared brightness temperature value through simulation based on the variable and the model information of the current meteorological satellite; and when a first preset time condition is satisfied, presenting the obtained infrared brightness temperature value in a meteorological cloud picture, and determining newborn convection information according to the displayed meteorological cloud picture. According to the technical scheme, the variable required for simulating the infrared brightness temperature value can be extracted from the weather forecast data based on the variable and the model information of the current meteorological satellite, the infrared brightness temperature value is obtained through simulation according to the variable, and then the primary convection information is determined through the infrared brightness temperature value; since the predictable duration of the weather forecast data is longer than that of the newborn convection, the forecasting capability of the newborn convection information is improved, and the forecasting duration of the newborn convection information is further improved.

Description

technical field [0001] Embodiments of the present invention relate to big data processing technology, and in particular to a method, device, device and storage medium for determining incipient convection information. Background technique [0002] In recent years, the number and intensity of severe convective weather (strong convective weather currently refers to convective gale, hail, and short-term heavy precipitation accompanied by thunderstorms) have been increasing. Although Doppler weather radar can provide high temporal and spatial resolution However, it detects precipitation particles, so the moment when convective clouds begin to form is delayed. With the improvement of the temporal and spatial resolution of meteorological satellites and the increase of spectral channels, the use of meteorological satellites to observe convective initiation (CI) become possible. Specifically, CI is defined as: Doppler weather radar detects for the first time the reflectivity produce...
