GOAL

To develop and test methods to improve short-term (0-24 h) forecasts of damaging weather on the U. S. West Coast in landfalling winter storms emerging from the data sparse Pacific Ocean.

WHY?

Impacts of landfalling Pacific winter storms on an annual average are comparable to those of earthquakes. Yet, their prediction is hindered by the fact that they develop over the ocean. The human and economic costs of these storms have increased dramatically in recent years.

WHEN?

January to February 2001

WHERE?

From 300 km inland to 1000 km offshore of the U.S. West Coast from Southern California to Washington State.

HOW?

Testing new ways to observe approaching storms; better ways to use existing data; improving understanding of key physical processes; exploring linkages between climate variability and extreme weather; and working with forecasters to develop new forecasting tools.

TOOLS

  • NOAA P-3 Orion Research Aircraft
  • Specialized Satellite Products and Validation
  • Coastal and Inland Wind Profiler Network
  • Coastal Process Study Site (Fluxes and Microphysics)
  • Assimilation of Data into Operational Forecast Models
  • Expanded-Domain RUC Model extending 1000 km offshore
  • Experimental Mesoscale Ensemble
