specific Embodiment approach 1

[0030] Specific implementation mode 1. Combination Figure 1 to Figure 9 In this embodiment, the high-performance calculation method of CALPUFF is realized based on workflow. The method is based on the atmospheric model calculation service system (platform) and consists of three systems, specifically including the atmospheric model management system, the atmospheric model calculation system and the task scheduling management system.

[0031] The third-party system interacts with the entire atmospheric model calculation service system through the atmospheric model management system;

[0032] The atmospheric model management system is used for user-oriented use and interaction with third-party systems; it is used to realize the management of computing models, case management, statistical analysis of model data, management of computing service interfaces, and system management functions;

[0033] The atmospheric model calculation system is responsible for completing the follow-up...

specific Embodiment approach 2

[0055] Specific embodiment two, combine Figure 3 to Figure 9 Describe this implementation mode, this implementation mode is the embodiment of the calculation method based on the workflow that realizes CALPUFF high performance described in the specific implementation mode one:

[0056] combine image 3 To illustrate this embodiment, the overall technical architecture of the atmospheric model computing service platform adopts the design methods of MVC and SOA, and the overall architecture can be divided into four layers, namely the basic layer, data layer, support layer and application layer.

[0057] Said MVC refers to a certain framework of the MVC pattern, which enforces the separation of input, processing and output of an application. Using MVC applications are divided into three core components: Model, View and Controller. They each handle their own tasks. The three-tier relationship is as Figure 4 shown.

[0058] The view layer view is the interface that the user se...

Abstract

The invention discloses a calculation method for realizing CALPUFF high performance based on workflow, relates to the technical field of atmospheric environment and computer processing, and solves the problems that an existing meteorological model is low in abnormal condition processing capacity, calculation cannot support concurrency, the calculation efficiency is low, the calculation result analysis processing capacity is insufficient, calculation of complex conditions of multiple models cannot be supported, and one script can be only used to solve a single question. The method is realized based on an atmospheric model calculation service system, and a calculation task is divided into a plurality of task nodes according to a workflow mode and is completed one by one. The method integrates complex data, analyzes and processes the data and realizes cloud service sharing, the atmospheric model calculation service system adopts a numerical simulation method to analyze atmospheric pollution causes under different weather conditions and at different times within a numerical model range, the contribution rate of each pollution source, various pollution sources and each grid pollution source influencing the atmospheric pollution is judged, and decision support is provided for prevention and control of the atmospheric pollution.

Description

technical field [0001] The present invention relates to atmospheric environment and computer processing technology field, be specifically related to a kind of method that realizes CALPUFF high-performance computing through workflow and platformization. Background technique [0002] Existing meteorological models of different scales include WRF, CALMET, and CALPUFF in sequence from large-scale to small-scale models. If you want accurate small-scale CALPUFF calculation results, you can calculate the WRF model first, then calculate the CALMET model, and then use the calculation results as the pre-calculation data of the CALPUFF model for CALPUFF model calculation. [0003] At present, most of the calculations in this mode are done manually, which has a large workload, low calculation efficiency, and is prone to errors. There are also a small number of simple script tools that connect the entire process in series, but this method has poor processing capabilities for various abn...
