Within the ICEWARN project, the Institute of Atmospheric Physics of CAS, Prague, and the Czech
Hydrometeorological Institute currently collaborate in developing and application of the FORTE model for a
linearly continuous road weather forecast in the city of Prague (1). The model stems from the METRo model (2),
the initial modifications being described in (3). The ensemble method (4) is not applied in the current project
ICEWARN. In cities, the impact of obstacles on the modification of radiation fluxes, and consequently on the
road temperature, is of a particular importance. The modification includes shading the direct shortwave
radiation and the sky view restriction. Our present contribution is focused on implementing and testing a
parametrization of these effects in the FORTE model.
When evaluating the model results for a winter period as a whole, shading effects were found for none of the
locations of road weather stations (RWS) in Prague. That was why we decided to test the model against the RWS
in the NW part of the Czech Republic.
