North towards the Arctic sea
False, It is not even a land mass, it is an ocean. The North Pole is a point which happens to fall in the Arctic Ocean. It can be reached by travelling over the pack ice of the Arctic Ice Sheet which covers the Arctic ocean.
The Arctic Oscillation describes a relationship between pressure fields in the Arctic which governs atmospheric mass distribution around the hemisphere. Central to it is its Polar Vortex, mostly in the stratosphere, that is usually manifested as strong easterly winds around the North Pole. In the negative phase of the AO, the vortex is weakened and this allows a more meridional flow - meaning more cold Arctic air can slide south, invading the lower latitudes. For different (dynamical) reasons, this more high-amplitude pattern is more conducive to the development and amplification of cyclones in Eastern North America and Western Europe. That's why it tends to be colder and snowier in these phases of the AO in these locations. Check out the related link for the standard diagram of the negative vs. positive phases.
The Arctic is north.
No because the North Pole is up above the Arctic Circle. Houston, Texas is down right above Mexico.
The North Pole is in the Arctic Region.
The Arctic is north
The region north of the Arctic Circle is known as the Arctic.
The motto of University of the Arctic is 'In the North, for the North, by the North'.
North Atlantic Oscillation
Canada has the longest coastline in the world. The Atlantic Ocean is to the east, the Pacific Ocean is to the west, and the Arctic Ocean is to the north.
