CINDY2011/DYNAMO MJO case simulated by the global cloud resolving model NICAM

An MJO case observed during CINDY2011/DYNAMO is simulated by a global cloud resolving model NICAM, as part as a large simulation series of Winter MJOs. A coherent envelope is apparent in the simulation. It travels eastward, accompanied with precipitation patterns and vertical structures that reasonably resemble the observed. This provides an opportunity to expand the scope of study and explore the evolution of the MJO with a virtual but full and broad dataset that complement the excellent dataset provided by CINDY2011/DYNAMO. Moisture and momentum budgets in the Indian Ocean are explored in relation with the development of the MJO convective envelope.
