Example Embodiment

[0033] Example 1

[0034] like figure 1 As shown, the precipitation forecast and early warning system of the complex terrain watershed of the present invention includes a weather live data module, a weather forecast data module, a forecast checking module, an information query module and a background management module.

[0035] The weather live data module includes collected rainfall, area rainfall, soil moisture and real-time early warning data:

[0036] Rainfall: rainfall monitored in real time by telemetry rainfall stations and automatic monitoring stations of the Meteorological Bureau within the basin;

[0037] Effective areal rainfall: Through the effective areal rainfall algorithm, the effective areal rainfall within the basin can be calculated in real time;

[0038] Soil moisture: soil moisture data monitored in real time by the soil moisture monitoring station;

[0039] Real-time early warning: For the rainfall and effective area rainfall at key points in the waters...

Abstract

The invention discloses a rainfall forecasting and early warning system for a complex terrain drainage basin. The rainfall forecasting and early warning system comprises a weather actual condition data module, a weather forecasting data module, a forecasting inspection module, an information query module and a background management module, the weather actual condition data module comprises collected rainfall, surface rainfall, soil humidity and real-time early warning data; the weather forecasting module comprises a short-term proximity forecasting module, a short-term and medium-term forecasting module and a long-term forecasting module, and the forecasting and checking module is used for checking the rainfall and the effective surface rainfall forecasted in the drainage basin range and the actual monitoring result to obtain the forecasting accuracy and deviation. Aiming at the problems that the rainfall forecasting range is not fine and the forecasting accuracy is low, the latest radar, rapid assimilation, multiple modes and other numerical forecasting results are utilized, and the actual underlying surface condition in the drainage basin range is combined to research and developa rainfall forecasting product which is updated hour by hour in the future 6 hours. The product can effectively make up for the defects of time and accuracy of existing rainfall forecasting.

Description

technical field [0001] The invention relates to a hydropower dispatching and commanding system, in particular to a precipitation forecasting and early warning system in complex terrain basins, and belongs to the field of hydropower emergency management and information technology. Background technique [0002] Scientific and safe hydropower production scheduling is not only related to the economic benefits of the hydropower industry, but also to the national economy and people's livelihood. Through scientific scheduling, the hydropower department opens the gates to generate electricity before the flood peak, which not only improves economic benefits, but also prevents dam breaks and effectively prevents the impact of floods on people's lives and properties. The most direct factor affecting hydropower production scheduling is the amount of atmospheric rainfall. However, due to the special terrain and landforms of mountainous areas, there are many types of natural disasters, s...
