1. A method comprising:
determining, by a control system, from among a plurality of categories, a current category of an incoming wind approaching a wind turbine, the plurality of categories including three or more of:
a first wind condition in which wind contacting an upper rotor of the wind turbine is veering and wind contacting a lower rotor of the wind turbine is veering,
a second wind condition in which the wind contacting the upper rotor of the wind turbine is veering and the wind contacting the lower rotor of the wind turbine is backing,
a third wind condition in which the wind contacting the upper rotor of the wind turbine is backing and the wind contacting the lower rotor of the wind turbine is veering, or
a fourth wind condition in which the wind contacting the upper rotor of the wind turbine is backing and the wind contacting the lower rotor of the wind turbine is backing; and
setting, by the control system, a yaw bias of the wind turbine according to a yaw bias value determined based on the current category.
