Abstract

The invention relates to the technical field of meteorological and hydrological forecasting and meteorological information processing, in particular to a regional atmospheric and hydrological coupling early warning decision-making system. The system comprises a regional data acquisition module for acquiring the regional data in real time; an artificial intelligence module which is used for obtaining a rainfall analysis model in the region; a rainfall forecast analysis module which is used for obtaining the rainfall amount and the rainfall path forecast in the region; a correction module which is used for obtaining the corrected precipitation amount and precipitation path forecast and storing the corrected precipitation amount and precipitation path forecast in a database; a hydrological data acquisition module which is used for acquiring the surface runoff data; a hydrological forecasting module which is used for providing water level forecasting, early warning and pre-discharging decisions in the region; a response demonstration module which is used for simulating the rainfall runoff trend in the region in several hours in the future and the convergence of rainfall to a low position on the ground so as to realize the runoff early warning and prediction; and an early-warning decision-making module which is used for determining an early-warning decision-making scheme according to a preset runoff monitoring point threshold value.

Description

technical field [0001] The invention belongs to the technical field of meteorological and hydrological forecasting and meteorological information processing, and in particular relates to a method and system for a regional atmospheric and hydrological coupling early warning decision-making system. Background technique [0002] Through the analysis of the scale characteristics of the weather system and the overview analysis of the weather and climate characteristics of heavy rain, it is shown that for the purpose of monitoring and early warning of disastrous small and medium-scale weather systems, conventional detection data cannot meet the application requirements at present. The distance between conventional sounding stations is generally 100 kilometers, and there are only two routine observations per day. In addition, the vertical distribution information of atmospheric parameters is especially important for the monitoring and early warning of disastrous weather. [0003] ...
