According to the invention, the method comprises exposing a surface () sensitive to relative wind and monitoring the thermal flow variations between the surface () and the aerodynamic flow, said variations resulting from that of the forced-convection thermal exchange coefficient between the surface () and the aerodynamic flow depending on the rime or ice build-up, using the temperature sensor () under the surface (), considering that stripping occurs by the flow of an ice layer formed on the surface () if it is detected, preferably after heating by at least one heater (), that there is a brisk rise of the flow at a temperature close to 0&#xb0; C., and supplying after the detection of ice stripping, a signal indicating the presence of rime or rime conditions. A cooler () may cool the surface () for anticipating the formation of ice with a heating process. The invention can be used for detecting rime and/or rime conditions on a flying aircraft.
