I'm trying to create a earth-like world, with different land masses. I want to make a realistic climate scheme and determining ocean currents is a part of this.
I've done some research on ocean currents and know that the gyres turn clockwise in the northern hemisphere and counterclockwise in the southern hemisphere. This I've already tried to draft on my map:
My problem: I'm not entirely sure what to do at the poles because, in contrast to earth, I don't want an Antarctica-like current going around the globe. I'm assuming ice caps at the north and south pole blocking this movement. (in the north the ice cap will reach the small continent in the middle of the map 1, in the south the ice cap will cover the most southern island and the southern edge of the continent above that island)
In the north, the current may pass between the two continents in the middle of the map [1 & 2], however the passage is maybe too small? And even so, the northern hemisphere will still have gyres?
Under the continent in the middle , the two gyres left and right of it are flowing in different directions. However I think this is no problem, because this is also happening under Africa.
I am not sure what will happen in the lower left part of the map ? Will there be a local gyre?
