GRAPES region set forecast inspection display system and method

Abstract

The invention belongs to the technical field of data detection, and discloses a GRAPES region set forecast inspection display system and method. The method comprises the steps of obtaining a written front-end page and a layout page; and then using a background to perform data processing, performing the foreground and background data interaction by using QtWebChannel based on the processed data, and responding to a data request of a foreground by adopting an iterative acceleration mode of reading the data from a database, reading the data from a server and storing the data into the database ifthe data is not read from the server, and then reading the data from the database. According to the invention, the basic parameters, such as the sea level height, the rainfall grade and the report starting mode of the chart, etc., can be conveniently adjusted. Compared with a traditional inspection and analysis display method, the data analysts do not need to repeatedly search in a pile of chartswith low efficiency, and can concentrate on the inspection and analysis of the forecast data, so that the analysis efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of data detection, and in particular relates to a GRAPES regional set forecast inspection display system and a display method. Background technique [0002] Currently, the closest prior art: [0003] In the existing technology, the application of most of the forecast inspection methods is limited to individuals writing codes to meet specific needs. There are some simple tools for specific inspection methods on the Internet, but my country has not yet had a complete integrated unified inspection tool. The inspection tool currently used by a department of the National Meteorological Center can only upload all the ensemble forecast data and then export all the analysis charts. If you want to compare and analyze the inspection scores of a certain variable at a specific time / time period, the operation will be very inconvenient. In fact, situations that require comparative analysis often occur; in addition, many ...

AI Technical Summary

Problems solved by technology

[0009] (1) At the present stage, tools for GRAPES regional ensemble forecast data detection are relatively lacking and immature. Due to the knowledge gap between developers and users, developers’ insufficient research on users’ usage habits, etc., it is difficult to develop However, it is inconvenient for users to use the previous tools to assist data detection, and the efficiency of data analysis is low.

[0010] (2) Most of the existing visualization tools are written by non-computer professionals using outdated programming languages ​​such as Fortran, with single functions and poor security, and the tool software is difficult to upgrade, expand or transplant;

[0011] (3) In the absence of an integrated and unified test analysis and display tool, it is very inconvenient for meteorological analysts to perform comparative analysis of a variable test score for a specific time / period, and it is necessary to manually extract from all relevant charts The required chart is produced, and the analysis efficiency is very low

[0012] (4) In some specific detection fields, there are not even auxiliary detection tools used in conjunction with them, and meteorological analysts can only use software with the function of drawing charts for auxiliary analysis
