Abstract:This study uses a spatial analysis and visualization technology to intelligently and similarly search for the regularity of the temporal and spatial variation of typhoons from 1949 to 2018 to form a comprehensive quantitative judgment system based on three key indicators, which are spatial location, feature elements and temporal rule, and to establish initially a unified judgment standard. According to path similarity determination, the method based on the combination of multiple dynamic fitting curves and similar deviation is proposed. The research results show that the comprehensive quantitative judgment system can effectively reduce the uncertainty of single index. And the dynamic judgment method can effectively solve the problem of observation point mismatch. Take Typhoon Mangkhut (1822) as an example. Firstly, we use retrieval methods 〖JP2〗as data cleaning, feature extraction and quick retrieval creation to narrow searching〖JP〗 range, retrieving 10 possible typhoons with similarity to the target, and then we use the comprehensive quantitative judgment method, confirming 7 similar typhoons. During the judgment process, three targets can be achieved, including the multi dimensional spatiotemporal data being drilled down step by step based on customized conditions, the quantitative comprehensive intelligent retrieval and the visualization of similarity results. This can provide important reference for typhoon forecast and early warning operation.
