When a wind is easterly, it blows from the east towards the west. However, when the wind is eastward, it blows from the west towards the east. The suffix is what determines the direction. "Ly" means from and "ward" means towards. From your example, I would say that the wind is coming FROM the north and blowing TOWARD the south.
When the map says NNW or SSW or any other direction; it means the wind is blowing from that direction.
Wind direction is the direction from which the wind originates. A northern wind blows south, it originates in the north. See the related link for more information.
A westerly wind comes from the west. All winds are named like this. In Britain a North wind is a cold wind, from the north.
South West...
Ignoring the coriolis effect, winds blow form high to low, therefore the wind would blow from west to east, it would be a westerly wind.
It is a south-westerly wind. Always named after the direction the wind comes FROM And if from south-west it blows at 180 degress to north-east so not at 90 degrees to south-east direction.
A wind that blows consistently from one direction is known as a prevailing wind. For example, over most of North America, the wind tends to blow from West to East, thus the prevailing Westerly.
A west wind blows FROM the west.
We name winds from the direction they come from. So north winds come from the north. East winds come from the east, and blow west. Winds can come out of any direction. The direction the winds come out of the most often depends on where you live.
From a generally westerly direction to a generally easterly one.
Ignoring the coriolis effect, winds blow form high to low, therefore the wind would blow from west to east, it would be a westerly wind.
A wind that blows from west to east is called a westerly wind. The direction of origin is the name of the wind.

If westerly winds blow from the southwest, they would drive water beneath them to the north. If the winds blew directly west, the wind would drive water currents directly east.

It is a south-westerly wind. Always named after the direction the wind comes FROM And if from south-west it blows at 180 degress to north-east so not at 90 degrees to south-east direction.
When wind blows from the west to the east it is referred to as the westerly's and in the mid-global latitudes of between 35 and 65 degrees they are called prevailing westerly's or prevailing winds.
I know that Michigan (and most of the Great Lakes area) has "westerly" prevailing winds. Unfortunately, I have been unable to find out whether that means the winds blow from the west (to the east) or to the west (from the east). I had a weather vane that seemed to point West pretty consisantly, which makes me believe that "westerly" prevailing winds must blow towards the west, although I can't say definitely. A Westerly wind, is blowing out of or comming from the west and moving east. So when you read a weather report it will say "NW at 9mph" meaning it is comming out of a northwesterly direction moving to the southeast and obviously the wind speed is 9mph.
A wind that blows consistently from one direction is known as a prevailing wind. For example, over most of North America, the wind tends to blow from West to East, thus the prevailing Westerly.
