Yes, the West Wind Drift, also known as the Antarctic Circumpolar Current, occurs at approximately 60 degrees south latitude in the Southern Hemisphere, not at the Arctic Circle in the Northern Hemisphere.
Geographically, the Arctic is that area around the north pole where the sun does not set at the summer soltice or rise at the winter soltice. This is latitude 66° 32' N which is called the Artic Circle. Climatically, the Arctic Region is defined as those northern areas where the July temperatures do not reach 50°F or 10°C. The latitude of these condions varies both north and south of the Arctic circle. Since they occur on all sides of the north pole, the Arctic, by either definition includes all longitudes.
Small populations
Genetic drift tends to occur in small populations where random events can have a significant impact on allele frequencies. This can lead to the loss of genetic variation and increased inbreeding.
The Arctic Circle is located at 66.5 degrees N because it marks the southernmost latitude where the sun can remain continuously above or below the horizon for a full 24 hours during the summer and winter solstices. This boundary is defined by the tilt of the Earth's axis relative to its orbit around the Sun.
False. Genetic drift is more likely to occur in small populations where chance events can have a greater impact on allele frequencies. In large populations, genetic drift is typically less influential compared to other evolutionary forces.
The Arctic Circle is in the Northern Hemisphere and encompasses the area around the North Pole, while the Antarctic Circle is in the Southern Hemisphere and surrounds the South Pole. The Arctic Circle is predominantly ocean surrounded by land, while the Antarctic Circle is mostly landmass surrounded by ocean. Both circles mark the latitudes where 24 hours of continuous daylight or darkness can occur, depending on the time of year.

It depends one what north you're talking about. Yes, they can hit the northern United States, but they don not occur, for example, withing the arctic circle.
Arctic ocean
The midnight sun occurs during the summer months in regions within the Arctic Circle and Antarctic Circle, when the sun remains visible at midnight, creating 24 hours of daylight. This phenomenon happens because of the tilt of Earth's axis towards the sun during these periods.

Tundra biomes generally occur near the Arctic Circle, between 60° to 75° latitude in the northern hemisphere. In the southern hemisphere, tundra biomes are found near the Antarctic Circle, between 60° to 75° latitude.
