I am taking a navigational course and part of it is about meteorology. There is one thing which is, although obvious, quite hard for me to grasp.
Looking at a global weather map like this: https://earth.nullschool.net I can see the High pressure area on the Atlantic pushing air towards Europe and into the Low pressure area in the North pole.
My understanding is that High pressure = Cold air, flowing clockwise and outwards. Viceversa for the Low pressure.
What I don't understand is why there is an area of High (cold) over the Atlantic in the tropics and Low (warm) in the Poles, while I would expect the Atlantic to be warmer than the North pole (and indeed it is, if you look at surface temperature). My expectation would be the opposite should happen.
