OPERATIONAL EXPERIENCE WITH ICEWARN MODEL (METRO-CZ) IN COMPARISON WITH OTHER TOOLS
Original language description
Successful forecast of road surface temperature (RST) and conditions is crucial for winter maintenance decision support as well as for warning system of national meteorological services. Czech Hydrometeorological Institute (CHMI) has been using outputs from the VAISALA FORECASTER for almost 20 years (22 sites mostly around the highways, 24 hours lead time) calculated four times per day. Since the 2013/2014 winter season we have had access to the Support System for Winter Maintenance (SSWM) operated by CROSS Zlín and KLIMATOR company. The outputs are in form of thermal maps and graphs calculated every hour with lead time 12 hours presented in the official Road Weather Information System (RWIS). The third source of RST forecasts is the ICEWARN system based on the METRo algorithm. METRo‐CZ version was developed by Institute of Atmospheric Physics AS CR and has been operated regularly by CHMI since winter 2014/2015 for internal use and further development with outputs adapted to the Visual Weather meteorological workstation software produced by IBL Software Engineering. Since February 2018 the graphs from METRo‐CZ have become regular alternative source of RST forecasts for RWIS and serve for the purpose of nowcasting and warning in some local systems as the ICEWARN (for Prague).
