The global eddy-resolving HYbrid Coordinate Ocean Model (HYCOM) is integrated for the period of CINDY/DYNAMO field campaign (fall/winter 2011). We use the version of global HYCOM with horizontal resolution 1/25 deg. with 32 layers in the vertical. HYCOM was spun up for 10 years with climatological atmospheric forcing fields derived from ERA-40. Then the model is integrated with archived operational forcing from the Navy Operational Global Atmospheric Prediction System (NOGAPS) for the period 2003-2011 that covers the field phase of CINDY/DYNAMO.
If the well-defined Madden-Julian oscillation (MJO) is observed during the ongoing field campaign, upper ocean response to the MJO in the global HYCOM will be described. Upper ocean variations associated with other atmospheric subseasonal variability observed during this period will also be discussed. Both local and remote responses such as the impact on the Indonesian Seas and Bay of Bengal may be included. Our results of the preliminary analysis will hopefully provide useful information for developing strategy of the model-data comparison.
