Climate simulation

AMIP-type runs integrated for period from 1991–2010

Every six hours.

AMIP-type runs with the observed SST specified as the lower boundary layer condition.

All AGCM runs employ the NCEP Optimally-Interpolated weekly SST and sea-ice datasets

Hindcast experiments –- short-term integrations

48 hours forecasts initialized every day at 00Z for a series of dates around the two specific MJO events :

Case 1): Oct. 20, 2009-Nov. 10, 2009

Case 2): Dec. 20, 2009-Jan. 10, 2010

Detailed time step outputs from the 48 hour forecast

Hindcast experiments –- long-term integrations

Largely similar to component 2, but (1) initialized daily over longer periods during the two selected MJO events;

(2) integrated for 20 days instead of 2 days in component;

(3) The output is to be provided on standard horizontal and vertical grids at every 3 hourly interval, using the same 2.5o by 2.5o grid

The specific periods to initialize the models for 20-day hindcasts in this component are as follows,

Case 1): Oct. 10, 2009-Nov. 25, 2009

Case 2): Dec. 10, 2009-Jan. 25, 2010

Every three hours.
