Experimental product for monitoring MJO and equatorial waves for monthly forecasting of cyclonic activity and weather patterns in the south-west Indian Ocean.

Target users: meteorologists, climatologists

The PISSARO project produces a weekly compilation of a set of data associated with the monthly forecast in the south-west Indian Ocean. The last 4 compilations of figures can be downloaded here (in french)(please note: weekly update stopped):

Here is an illustration of the product with an extract of the monthly forecast support in the south-west Indian Ocean produced on 9 February 2022 in the framework of the PISSARO project:

A forecasting methodology on a monthly and regional scale for the French overseas territories, leaving room for human expertise, has been developed thanks to a strong collaboration between the ENM (Ecole Nationale de Météorologie) and the CNRM (Centre National de Recherches Météorologiques). This methodology involves “human” expertise and the physical concepts of subseasonal forcing. The experts study MJO (Madden-Julian Oscillation) indices, equatorial wave filtering products, MJO composite maps and multi-set numerical outputs that are compiled into a presentation medium. During the cyclonic season, this medium is produced almost automatically on a weekly basis and is formally reviewed once a month (in the form of a monthly briefing) by the experts.
