bearing
From Glossary of Meteorology
The horizontal direction from one terrestrial point to another; basically synonymous with azimuth.
Bearing, however, may be expressed in several ways: true bearing and magnetic bearing are the angular directions in degrees measured clockwise from true north and magnetic north, respectively; compass bearing is expressed in terms of compass points; and relative bearing is the angular distance measured clockwise from the heading of a craft (in aviation, relative bearing is often referred to a clock face, that is, "3 o'clock" equals a relative bearing of 90°, etc.).
