Description:

The Madden–Julian Oscillation (MJO) teleconnections diagnostics package is an open-source Python software package that provides process-level evaluation of MJO teleconnections predicted by subseasonal-to-seasonal (S2S) forecast systems. The package provides in-depth process level evaluation of both tropospheric and stratospheric pathways defining the atmospheric teleconnections from the tropics to the extratropics on S2S time scales. The analyses include the comparison of a forecast model with a default verification dataset or user-provided verification data. The package consists of a user-friendly graphical user interface (GUI), which allows the package to be applied to both operational and research models. This approach allows for efficient data management and the reproducibility of the analysis.
