This won't add anything of substance to this topic. ;-)

I think the terms westerly, northerly, etc. are pre-scientific usages that have
persisted into scientific applications. From a physicist's point a view, air
moving from north to south would have a velocity vector pointing southward. The
average person, however, is more interested in where the wind is coming from
than where is is going to (a northerly wind, being from the north, is cold, etc.)

To confuse things further, the oceanographic usage is the reverse of the
meteorological usage. That is, an easterly current is toward the east. This
does make sense, as a ship is more interested in where a current will carry it,
than where the water came from.

The dictionary has both senses of the word (toward and east as well as from the
east). To avoid confusion, I tend to use westward, rather than easterly.
