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, comprising: a regional data acquisition module, used to obtain regional data in real time; an artificial intelligence module, used to obtain available information in the region Precipitation analysis model; precipitation forecast analysis module, used to obtain the precipitation and precipitation path forecast in the region; correction module, used to obtain the revised precipitation and precipitation path forecast, and store them in the database; hydrological data acquisition module , used to obtain surface runoff data; hydrological forecast module, used to provide water level forecast, early warning and pre-release decision-making in the region; response demonstration module, used to simulate the precipitation runoff trend in the region and the precipitation on the ground in the next few hours The low-level confluence realizes early warning and forecasting of runoff; the early warning decision-making module is used to determine the early warning decision-making scheme according to the preset threshold of runoff monitoring points.
Description
A regional atmospheric hydrology coupled early warning decision-making system and method technical field The invention belongs to meteorological and hydrological forecasting and meteorological information processing technical field, be specifically related to a kind of regional atmospheric hydrology Coupled early warning decision-making system method and 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 torrential rain, it is shown that with catastrophic For the purpose of monitoring and early warning of small and medium-scale weather systems, at present, conventional detection data cannot meet the application requirements. conventional sounding station The distance is generally 100 kilometers, and there are only two routine observations per day. In addition, for the monitoring and early warning of severe weather Information on the verti...
