Abstract:
Correlation analysis is widely used in meteorological research and practice, and it is an important tool for the quantitative analysis of the relationship between meteorological variables. In the present study, correlation analysis algorithms of different calculation forms used in meteorological research and practice are summarized. Then, the latest development of using correlation analysis in meteorology is introduced, especially the full sliding window correlation and correlation coefficient scanning multi-scale change points detection algorithm developed by us. In addition, it introduces the newly developed correlation analysis algorithm in big data research and analyzes its use for meteorological correlation analysis. Finally, the existing problems in meteorological correlation analysis are analyzed, and the trend of correlation analysis in meteorology is presented.
Key words:  correlation analysis  correlation coefficient  full sliding window correlations  multi-scale change points detection  big data
