    Help Making a believable climate

    I'd like, if possible, to create a believable and livable climate on this world map of mine. Assuming that the world is as close to Earthlike as is reasonable in terms of angle/volcanic activity/density/position and all that, what do you think of it? I've done some work in an ancient copy of Photoshop Essentials to nail down the basics of geography and climate so that I can later go back and edit it to a level where I like it more, and then top it all off with some cultural worldbuilding.

    In the future, I'd like to add rivers and other bodies of water as well as proper Biomes. I have looked over Geoff's Climate Cookbook, but I'm unable to get through the section about gyres and currents, which seems alternately arbitrary or impossible to me. I'd like to get it settled out.

    Here is the topographical map, just set on a plain background, let's say that every color difference is 400 to 500 meters or so.

    Here is the tectonic map as well, so that you can see my thought process in creating the topography. Critique on these first two images is welcome!

    Now comes the tricky bit-- currents. I've put in general grey loops where I think that general, large oceanic gyres MIGHT go. Even once they're in place, I'm kind of lost as to how they create climates, but I'm going to look into it and figure it out. If you guys could help, I'd really appreciate it.

    If you guys are interested, I can post some progress reports about the world. Thanks in advance for helping me out.

    You should have only 3 gyres. Unless they encounter a large landmasses they will flow all around the planet.

    South hemisphere: 1 The gyre starts at the equator with the current flowing westward and bends against the eastern coast of the south continent. It follow the coast til it reaches 45 degree, more or less. Then, it moves to the east to complete the gyre.
    2 follow the same pattern but move in the opposite direction.

    North:
    3:unless the waters are shallow, it should be just one current.
    4: probably not a gyre since there are no significative exchange of water/energy with the other currents.

    Totally in agreement with Azelor.

    I would add that your world is almost a pure waterworld. This will surely influence the climate in ways that we do not understand from our experience on Earth...
