"The ESTOFS-Pacific was implemented operationally by NCEP Central Operations (NCO) on the Weather and Climate Operational Supercomputing System (WCOSS) to provide 180-hr forecast guidance of surge combined with tides, astronomical tides, and sub-tidal water levels (the isolated surge) throughout the domain. The ESTOFS provides the National Weather Service (NWS) with a second extratropical surge system in addition to the Extratropical Storm Surge (ETSS) model that currently is based on the Sea Lake and Overland Surge from Hurricanes (SLOSH) model (Jelesnianski et al., 1992). ESTOFS-Pacific fills NWS gaps in operational storm surge and tide modeling coverage in Hawaii. This model serves the needs of local Weather Forecast Offices (WFOs) for coastal marine forecasts. Forecasters will benefit from the gridded astronomic tide predictions that are provided by ESTOFS-Pacific, which can be combined with any gridded surge prediction (generated from model guidance or forecaster). The ESTOFS is also designed to provide the surge with tides to WAVEWATCH III® (WW3) for coupling wave predictions to coastal water levels. ESTOFS uses the same Global Forecast System (GFS) forcing and has the same forecast cycle and length as WW3. Output from ESTOFS-Pacific is disseminated by NCEP's Ocean Prediction Center (OPC) and NWS' Office of Science and Technology/Meteorological Development Laboratory (OST/MDL)"--Page vii.

"This report is broken into 6 sections, the first of which is this introduction. Section 2 of this report focuses on an overview of ESTOFS including a brief description of ADCIRC, the model grid for this application, the input files, and system interruption and recovery procedures. Section 3 describes the model run scenarios for an as tronomical tide simulation, a hindcast simulation, and a semi-operational forecast simulation. A summary of the NOS skill assessment criteria and the NOS/Center for Operational Oceanographic Products and Services (CO-OPS) observation stations along the Atlantic and Gulf of Mexico coasts of United States are summarized in Section 4. Lastly, the performance of the model is examined using the skill assessment criteria in Section 5. Section 6 presents a summary of the ESTOFS skill assessment"--Introduction.

Simulations with high resolution air/sea coupled models and several case studies have lead to the hypothesis that friction parameterizations could have a profound affect on the accuracy of numerical analysis and prediction of decaying cyclones. In this study, analyzed and forecast characteristics of decaying cyclones over the North Pacific Ocean are related to the hypothesized importance of friction induced cyclone spin down. Many characteristics of cyclolysis, which include gale area size and decay rate, were found to vary according to the synoptic-scale conditions in which the cyclone exists. Furthermore, the hypothesized relationship between cyclolysis and frictionally forced spin down was not found to exist in the analyzed and forecast model data. This result might be expected since friction spin down is parameterized based on analyzed and forecast winds over synoptic space and time scales. Therefore, it is concluded that over these scales other factors, which may include energy transfers due to barotropic processes, contribute in a major way to cyclone decay as portrayed in a global-scale numerical model.

The National Weather Service (NWS) has developed a technique for forecasting extratropical storm surges along the northeast coast of the United States. The storm surge is caused mainly by the strong winds associated with extra-tropical storms over nearshore areas.
