Abstract

The invention provides a global seamless typhoon power set prediction method and system, and the method comprises the steps of assimilating multivariate observation data into a pre-established climate system mode through a growth analysis updating IAU method, so as to provide an initial field, and carrying out the parallel calculation on a super computer to generate a 36-year back calculation data set and a real-time prediction data set; according to the back calculation data set and the real-time prediction data set, selecting typhoon signals from the pre-established climate system mode prediction results by adopting a typhoon signal direct identification method; subjecting the selected typhoon signals to post-processing, and forming and issuing prediction pictures. According to the global seamless typhoon power set prediction method and system, global typhoon multi-time scale prediction can be realized, and ocean and sea ice modules are considered in a climate system mode coupling process, so that the prediction precision is improved.

Description

technical field [0001] The present invention relates to the technical field of typhoon forecasting, in particular to a global seamless typhoon power set forecasting method and system. Background technique [0002] The climate system is a highly complex system composed of five main parts: the atmosphere, the hydrosphere, the lithosphere, the cryosphere, and the biosphere. The mutual influence among the internal circles involves the interaction and material exchange between different media and different scales. [0003] The climate system model is a mathematical expression of the above-mentioned climate system, so that people can use supercomputers to perform quantitative, long-term, and large-scale calculations on the complex evolution processes involved, so as to grasp the evolution of the climate system processes, modeling external forcing changes and the effects of human activities, and predicting future climate change trends. The mathematical representation of the clima...
