Embodiment Construction

[0016] The present invention takes the Axel downloading tool as an example to further describe a global forecasting system data downloading method proposed by the present invention, but the present invention is not limited to the downloading tool.

[0017] There are 3 scripts included in the present invention. They are data download script, data maintenance script and data stop script. The data download script catchGFS.sh is used to call the Axel process to download GFS data. The data maintenance script patronum.sh is used to monitor and adjust the data download process (the Axel download process and the catchGFS script process are collectively referred to as the data download process in the present invention). The GFS data stop script stop.sh is a program used to terminate the data download process.

[0018] The overall flow of a global forecast system data download method proposed by the present invention is as follows: figure 1 shown, including the following steps:

Abstract

The invention relates to a global forecasting system data downloading method, and belongs to the technical field of weather data downloading. The method contains a data downloading script, a data maintaining script and a data stopping script, wherein the data downloading script is used for downloading GFS data by calling Axel procedure; the data maintaining script is used for monitoring and adjusting data downloading progress; and the GFS data stop script is used for terminating a program in the data downloading progress. By use of the method disclosed by the invention, the problems that the downloading is jammed and a file with remnant state is downloaded are effectively solved, and the downloading progress is not interfered by the network environment. The effect of intermittently and stably downloading the global weather forecasting data is achieved.

Description

technical field [0001] The invention belongs to the technical field of meteorological data downloading, in particular to a method for downloading a forecast field from a Global Forecasting System (GFS, Global Forecasting System). This method can download GFS data stably and efficiently under the condition of poor network conditions. Background technique [0002] Accurate precipitation forecast is an important prerequisite for water conservancy operations such as hydropower dispatching, flood control and disaster reduction. With the rapid development of meteorology and computer technology, numerical weather prediction has gradually become the mainstream precipitation forecast method, providing important intelligence information for various water conservancy operations. The download of initial and boundary data is an important task in numerical weather prediction. At present, China, the United States, Japan, Europe, Canada and other countries regularly release global initial...
