Estimated Improvement in Forecasts of the SANBAR Hurricane Model Using the Airborne Weather Reconnaissance System (AWRS).
Abstract
SANBAR is a one level, barotropic model that forecasts hurricane position. Inputs such as storm movement and maximum winds were selectively varied to measure sensitivity to errors. SANBAR is most sensitive to movement error and somewhat sensitive to errors in maximum wind. Movement error depends primarily on the errors in successive storm fixes. Knowing the current aircraft error, forecast error can be split into modeling error and observational error. Using the new Airborne Weather Reconnaissance System observations, the SANBAR 24-hour mean vector error is expected to be 60 NM versus the current 113 NM.
