ICEWARN – ROAD WEATHER FORECASTING FOR PRAGUE CITY

Popis výsledku v původním jazyce

The Institute of Atmospheric Physics (IAP) CAS, Prague, and the Czech Hydrometeorological Institute (CHMI)nhave developed and currently run FORTE model for Road Surface Temperature (RST) and Road SurfacenCondition (RSC) forecasts within the ICEWARN project. The goal of the project is to develop a method for anlinearly continuous forecast of RST and RSC in Prague city. The model stems from the METRo model (METRo,nCrevier and Delage, 2001) and is based on solving the energy balance and heat conduction equations. ThenFORTE model differs mainly in detailed check of input data (i.e., data quality control) and that radiationnfluxes are calculated taking into account shadowing of direct sun radiation by obstacles along the roads. Innaddition, the model is run every hour in nowcasting mode, when a potential risk on roads is expected. Thenmodel uses measured data from road weather stations (RWS), and forecasts of the numerical weathernprediction (NWP) model ALADIN as inputs to prepare temperature, radiation and precipitation forecastsn(Sokol et al., 2014, 2017). The model utilizes detailed topography, such as parameters of buildings, woodsnand orography, which can influence direct solar radiation.nnThe forecasting system ICEWARN enabling a 1‐h linear forecast of the RST and RSC has been successfullyndeveloped for Prague city roads and its operational run is planned in the near future. The next step isnimplementation and assessment of the impact of sky‐view factor.
