Claim 11:
12. The method according to claim 1, wherein:
for the icing criteria, a higher sensitivity icing area is defined as a range of weather parameters including an area in a parameter space along an icing border, and icing is expected for a weather point inside the higher sensitivity icing area if an abnormal operation situation is identified,
the abnormal operation situation is identified if an operating point exceeds a predefined deviation from a predefined reference value for longer than a predetermined minimum delay, and
the abnormal operation situation is identified if a power exceeds a predefined power curve and/or if a blade angle exceeds a predefined blade angle curve for longer than a predetermined minimum delay.
