Title:

Impact of High Resolution Site Specific Modelling on Road Surface Temperature Forecasts

Abstract:

The use of a Site Specific Forecast Model (SSFM), a high resolution ID local forecasting model forced from either 3D global or mesoscale NWP output, in road weather forecasting is demonstrated. This brings with it the potential for improvements in the atmospheric forecast data used to drive a road surface temperature model. Futhermore, this allows the automation of labor in the production of the large number of road weather forecasts currently provided. The SSFM takes account of the local environment surrounding the site and models the boundary layer evolution in more detail. Results from two winter trials are presented and show significant improvements in forecast accuracy.
