aircraft icing algorithms based on ECMWF forecasts

What is it about?

In-flight icing is one of the major weather hazards to aviation, in particular, for aircraft operating at lower altitudes. Therefore, forecasting the regions of potential icing is an important challenge to meteorologists. In-flight icing is the accretion of supercooled liquid water onto an airplane during flight. The main meteorological parameters that influence the severity and type of icing are temperature, liquid water content and droplet size. The extremely hazardous aircraft icing conditions are commonly found in clouds with temperatures between 0 and -16ºC. An objective verification of different icing algorithms based on ECMWF forecast is presented.
