2015 NOAA Climate Test Bed Meeting

November 9-10, 2015  The NOAA Climate Test Bed (CTB) Meeting was held in NOAA Center for Weather and Climate Prediction Conference Center with over 80 participants including NOAA management, and scientists from the external community and NCEP (EMC and CPC). The meeting has reviewed the CTB recent accomplishments, ongoing R2O activities and R2O/O2R process. The meeting participants discussed the needs for more effective R2O transition for improved climate models and operational products and future CTB directions based on NWS operational requirements and science advances/opportunities. The outcomes of the CTB meeting will help inform the updated CTB 5-10 year Science Plan and Implementation Strategy.

Recent CTB Seminars

November 13, 2015   A CTB seminar on Evaluation of Tropical Pacific Observing Systems Using NCEP and GFDL Ocean Data Assimilation Systems was held at the NCWCP Conference Center. Motivated by the recent rapid decline of the TAO/TRITON array, the potential utility of TAO/TRITON was assessed for ENSO monitoring and prediction. Dr. Yan Xue of Climate Prediction Center reported on a series of coordinated Observing Systems Experiments using the global ocean data assimilation system (GODAS) from the National Centers for Environmental Prediction and the ensemble coupled data assimilation (ECDA) from the Geophysical Fluid and Dynamical Laboratory for the period 2004-2011, when observations from Argo floats were also available. The results suggest that multiple ocean data assimilation systems should be used to assess sensitivity of ocean analyses to changes in the distribution of ocean observations to get more robust results that can guide the design of future tropical Pacific observing systems.

November 12, 2015   Dr. Ken Takahashi from Geophysical Institute of Peru gave a CPC/CTB seminar entitled "Eastern Pacific Feedbacks and the Forecast of Extreme El Niño Events" at the NOAA Center for Weather and Climate Prediction, College Park MD. His research demonstrated that extreme El Niño events, such as the ones in 1982-1983 and 1997-1998, corresponded to a separate dynamical regime resulted from nonlinear feedbacks in the eastern Pacific, where the triggering of deep convection and the associated amplification of Bjerknes feedback played an important role in the growth of extreme El Niño events. It further showed large westerly wind around August can be a predictor of kick-starting extreme El Niño event.
