LONG-TERM GOAL. My long-term research goal is to contribute to the advancement of the observation, structural analysis, dynamical diagnosis, conceptual model formulation, and numerical prediction of the life cycles of synoptic-scale and mesoscale extratropical weather systems, including the influence of planetary-scale inter-annual and intra-seasonal variability on their evolution. These weather systems include: extratropical oceanic and land-falling cyclones, fronts and their associated cloud, wind, and precipitation systems; upper-level jet streams and clear-air turbulence, extreme topographic flows and their interactions with the ocean. OBJECTIVES. My research over the past year focused on four primary objectives: i) the synoptic (manual) analysis and four-dimensional data assimilation of field campaign data sets gathered during the Fronts and Atlantic Storm-Track Experiment (FASTEX, 1997), North Pacific Experiment (NORPEX, 1998), and Winter Storm Reconnaissance Program (WSRP 1999), ii) the coordination and design of the of the US Weather Research Program (USWRP) priority research initiative for the optimal mix and implementation of current and next generation operational observing system for improved 1-7 day weather forecasts, iii) the diagnosis and dynamical interpretation of research and operational targeted observations over the North Atlantic and North Pacific oceans, and the impact of these observations on 2-7 day weather forecasts over the North America and western Europe, respectively, and iv) the numerical simulation and observational validation of high-spatial resolution (10 km) numerical predictions.
