Phase composites and process-oriented diagnosis of MJO teleconnections
Phase composites and process-oriented diagnosis of MJO teleconnections
The teleconnection diagnostics first generate maps of MJO phase composites
of 250 hPa geopotential height and precipitation for observations and
several CMIP5 models, putting behavior of the candidate model within this
cloud of models and observations. Then, average teleconnection performance
across all MJO phases defined using a pattern correlation of geopotential
height anomalies is assessed relative to 1) MJO simulation skill and 2)
biases in the North Pacific jet zonal winds to determine reasons for
possible poor teleconnections. Performance of the candidate model is
assessed relative to a cloud of observations and CMIP5 simulations.
