Main Goals
Working in concert with the WCRP-WWRP/WGNE MJO Task Force, effort will be focused on research, model evaluation and predictability/prediction skill studies on the interactions between the Maritime Continent (MC) and the MJO.
This focus is motivated by the perception that the MC represents a natural predictability barrier for the MJO that is exacerbated by limited understanding of the MC as a natural predictability barrier and also to a great extent by our limitations in model representations of the MJO and MC interactions.
The subproject can exploit a number of modeling and observational resources, namely:
- Dynamics of the Madden-Julian Oscillation (DYNAMO)
- Planning for a new MC field experiment in the 2017 timeframe - Year of Maritime Continent
I would like to share with you the paper on MJO, written by Masanori Yamasaki, who is famous for typhoon simulation. The paper is available on line at http://www.hindawi.com/journals/amete/2011/296914/ref/
He discussed the importance of the SST over the warm pool region in aqua planet model configuration, using his 20 km resolution meso-convective system model. If the SST is not warm, the transient (dry Kelvin wave) component is dominant, but the SST is warm enough over the warm pool, the stationary component is dominant, with clear multi-scale convection activities.
The S2S project and MJO subproject encourages the community to describe their research activities and plans, as well as observations and modeling resources, that might have relevance to the various subprojects - in this case related to MJO - MC interactions. The next entry is an example of this sort of expression of interest.
