Question

What is the surface wind direction in the northern pacific ocean (45°n 155°w)?

Answer 1

In the Northern Pacific Ocean, around (45°n 155°w), we get a counter-clockwise spinning wind, also called the geostrophic wind.

If you are are at 45°n, the low pressure polar winds will be at your north and the prevailing wind will be from your west. 

The direction of the wind is influenced by the air pressure and temperature and this knowledge was essential in order for sailors in the old days to navigate the open seas with sail boats.
