Traditional ocean models use a single coordinate type to represent the vertical, but model comparison exercises performed in Europe (DYnamics of North Atlantic MOdels - DYNAMO) (Willebrand et al., 2001) and in the United States (Data Assimilation and Model Evaluation Experiment - DAMEE) (Chassignet et al., 2000) have shown that none of the three main vertical coordinates presently in use (depth [z-levels], density [isopycnal layers], or terrain-following [sigma-levels]) can by itself, be optimal everywhere in the ocean. The HYbrid Coordinate Ocean Model (HYCOM) (Bleck, 2002) is configured to combine all three of these vertical coordinate types. It is isopycnal in the open, stratified ocean, but uses the layered continuity equation to make a dynamically smooth transition to a terrain-following coordinate in shallow coastal regions, and to z-level coordinates in the mixed layer and/or unstratified seas. The hybrid coordinate extends the geographic range of applicability of traditional isopycnic coordinate circulation models toward shallow coastal seas and unstratified parts of the world ocean. It maintains the significant advantages of an isopycnal model in stratified regions while allowing more vertical resolution near the surface and in shallow coastal areas, hence providing a better representation of the upper ocean physics","PeriodicalId":173959,"journal":{"name":"2006 HPCMP Users Group Conference (HPCMP-UGC'06)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129907281","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mechanical turbulence at these altitudes will impact surveillance and reconnaissance aircraft, both manned and unmanned. To address this problem the Air Force Research Laboratory, including the Air Force Office of Scientific Research, is conducting a research program with the ultimate goal of developing viable methods of predicting both mechanical and optical turbulence at these altitudes. A key factor in developing real-time forecasting ability for HAT is that the techniques must rely on input from the output of mesoscale numerical weather prediction (NWP) models. This is a challenge since HAT typically occurs within small vertical extents that are currently beyond the ability of the mesoscale NWP models to resolve. Challenge proj ect C1W was established in 2005 to support this program. Last year important simulations of Kelvin-Helmholtz shear instabilities (leveraged with CAP project time; see Werne 2005 for details) and inertial-gravity waves emitted and propagating from a jet stream were carried out. For a review of the 2005 effort see Ruggiero et al. (2005). Simulations of the above phenomena continued this year, along with more detailed analysis of the results including matching the simulations to observations. In this paper, the simulations of the atmospheric microscale code for jet stream induced gravity waves and turbulence will be presented. A case study over Greenland including a comparison of observations and direct numerical simulations (DNS) for Kelvin-Helmholtz instabilities and its implication for existing Kelvin-Helmholtz turbulence evolution theory and parameterizations are discussed","PeriodicalId":173959,"journal":{"name":"2006 HPCMP Users Group Conference (HPCMP-UGC'06)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126606398","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
