National Weather Service FY 14 Plans: Sandy Supplemental Augmentation

National Weather Service 6 Operational (T574~ 27km)Experiment (T1500~ 13km) Note: Last 24h of the high resolution experiment track based on 6h model output Hypothesis: Increased horizontal resolution resolves complicated Atlantic blocking pattern, slows simulated hurricane, and allows it to curve toward the East Coast Model Initialized at 00UTC 24 October Day Sea level Pressure (mb) Forecast valid at 00UTC 31 October 2012 Hurricane Position Shown Every 24h Increasing NCEP Global Model Horizontal Resolution Improves Hurricane Sandy Track Guidance

National Weather Service Summary 7 Earth system multi-model ensemble approach is a dominant basis for advancing predictions  Basis for NWS Strategic Goal Operational computer capacity will be increased to petaflop levels 4-D Hybrid Data Assimilation is a key development area for improving the model performance and fully utilizing new observing systems Challenges remain: End to End capabilities Observations – Data Assimilation – Models - Dissemination
