What is it about?

The current study examines the core and potential drivers causing the 2020 November rainfall to deviate from its historical response to the La Niña event. The driving force responsible for the wetter-than-anticipated 2020 November rainy conditions was identified.

Why is it important?

The diversity of mechanisms of MJO influence is relevant to problems of sub-seasonal weather forecasts for EA.


In summary, the study’s reflective constructs or discovery is realizing rainfall modulation for a particular MJO phase during La Niña may enhance sub-seasonal forecasting during short-rain periods in EA. However, even though they take into account information about the MJO and ENSO, and how they interact, sub-seasonal and seasonal predictions can be useful for planning and preparedness purposes.
