Wow, thanks Charerg! It makes the parts I had difficulty with seem so easily solved now!

@Azelor, Thanks for your explanations - I am slowly getting a better grasp of how they might work.

With Charerg's suggestions, I think I only have one final question/comment:

I think the north-east current at the top of the eastern continent around 45 degrees would be flowing to the west here because westerlies would still be dominant? I imagine it would be mild as it is fed by the warm current coming (a long way) from the equator, but I can also imagine it as cold because of the latitude and the polar current's influence?

I have tried to indicate currents I think would be mild in green.

Thanks once again! I will hopefully be able to figure out winds and start the climate maps soon.
