>I also don't know why that warm current split into two off that peninsula.
Its because fluid mechanics are very complex, and modeling then pseudo-accurately takes away from the usefulness of the map. The ocean current map is there to show an easily understandable, but very simplified image of how the currents would affect different areas.

You could thing of that split as modeling a loss of coherence for the ocean current. It becomes less defined as a singular current and breaks off into multiple small ones that furthermore mix together in various ways.

Pic related, its a very rough approximation of how the ocean currents may look like if detailed. I did not think about the arrow colours much, so dont take them as factual. The point is merely to show how currents move.
Below is a real world example of a comparable current - the Gulf Stream evolving into the north atlantic drift (current), with arrow colours that should be familiar. The cold current coming in from the north is the Labrador current.

Another example, of what may be happening north and west of /uuu/. Norwegian current fading and evolving into what I believe is the transpolar drift stream, as well as contributing to the east greenland current.

Do you define strength by velocity, or volume?
Latitude through coriolis effect is a major factor, but surface winds also drive them, as do of course, other currents. Various other factors also come to mind, water density and salinity. Ocean floor topology can steer currents, just the same as continents can.
I suppose if you took a lot of water and squeezed it through a smaller gap, it would move faster, but in total the same volume of water as enters the gap would come out the other side. You increase velocity, but not volume.
