Embodiment Construction

[0024] Below in conjunction with accompanying drawing, take the emergency meteorological service of a gas pipeline accident as an example, the present invention will be further described. The background of this emergency service is that on July 20, 2016, heavy rainfall caused mudslides and landslides, which caused the pipeline burst near the valve room of Cuiba Town, Jianshi County, Enshi County, Hubei Province, which was sent by Sinopec from Sichuan to East. precipitation forecast. It is necessary to point out here that the following specific embodiments are only used to further illustrate the present invention, and cannot be interpreted as limiting the protection scope of the present invention. Those skilled in the art can make some non-essential improvements to the present invention according to the above-mentioned content of the invention and adjust.

[0025] According to a single-point precipitation forecast method based on Beidou positioning proposed by the present inve...

Abstract

The invention belongs to the technical field of meteorological science, and particularly provides a Beidou positioning-based single point precipitation forecasting method. The method comprises the following steps: obtaining ensemble forecasting-based grid point precipitation data by improving a precipitation TS score to a multi-level percentage score, fusing multi-source precipitation observation data by using a data fusion algorithm to obtain the precipitation forecasting data of each grid point, and determining a single point precipitation forecasting value by combining Beidou precise positioning with an established single point precipitation forecasting quantitative calculation equation. The single point precipitation forecasting method provided by the invention is used for improving the forecasting accuracy rate and providing technical support for meteorological services such as disaster relief and key projects.

Description

technical field [0001] The invention relates to the technical field of meteorology, in particular to a single-point precipitation forecasting method based on Beidou positioning. Background technique [0002] Single-point precipitation forecast refers to the fine-grained precipitation forecast required for emergency rescue and disaster relief, construction and other operations at a certain location without a meteorological observation station. The degree of refinement and accuracy of the forecast has an important impact on command decision-making and organizational arrangements. [0003] In the previous single-point precipitation forecasting for emergency services, the routine is to use rough positioning information to find some kind of numerical forecast grid data closest to the point as the basic data, supplemented by nearby automatic stations, radar, sounding and other meteorological data. Manual correction. Due to the uneven distribution of meteorological observation st...
