Research Highlight


MJO Diagnostics for Extended Range Prediction and Simulation in IITM CFSv2

Reconstructed OLR anomalies over Central India and Indian Ocean. Black curve based on lagged phase composite method (previous 45  and forward 45 days of current day), takes seasonality into account and red curve based on simple phase composite method (considering all the days of the year).

Conclusion: The main advantages of the proposed EEOF based system are:

(a) Smoother propagation of convection associated with MJO, which would be useful for real-time applications

(b) Pre-filtering of data is kept to minimum and yet tracks of smooth MJO propagation could be obtained. This method could be directly used for comparison of model Forecast.

(c) MJO filtering could be done for any space-time data and not only with the variable used in filtering

(d) long model integrations are not required for tracking the model generated MJO

(e) MJO and the boreal summer intraseasonal oscillations could be treated with a uniform framework.
