or lateral component of wind

see:

The steering technique applied in the course of aircraft landing in the touchdown phase utilized the lateral bank as a countermeasure to balance lateral wind component. It resulted in touchdown on one main undercarriage leg only and in false impression on the part of the crew that touchdown was efficient. In reality the immediate start of operation of braking devices was not possible."
