When a fighter aircraft or missile flies at high angle of attack(AOA), asymmetric vortexes are produced from the forebody and induce strong side force and yawing moment.
飞机或导弹在大迎角下飞行时会形成非对称涡，从而产生很大的侧滑力和偏航力矩。

The yawing can apparently attenuate the angular displacement of both the tail and the attack angle of tail fin.
