Abstract: A method is proposed for in-flight icing prediction up to 12 hours based on the output of the COSMO-Ru configuration of the COSMO model with a grid step of 6.6 km for the Russian Federation area. The calculation of the simplified forecast icing potential (SFIP) using model microphysics data versus AIREP Speci information allowed determining a threshold value of , the exceeding of which is an icing criterion. A good agreement was found between the icing zones obtained by SFIP and the areas identified according to the condition , . To distinguish severe icing, it is proposed to use the values of model liquid water content exceeding 0.4 g/kg [ABSTRACT FROM AUTHOR]
