Ocean currents, climates & Biomes help

[Storminator]

Hello all!

So, I'm currently working on a world map for a worldbuilding project. The planet is generally the same as our Earth in rotation, axial tilt, etc. Only real difference is the landmasses as this is my first serious attempt at this.

As the title says, I've hit a bit of a snag. I have the general elevation map (The one below is slightly simplified, green being lows and grey being highs):


Basically, I can't seem to wrap my head around the wind patterns, ocean currents, etc to determine the climates and biomes. Any help with this and just some constructive critique on the map in general would be much appreciated, as I feel this is an area where I'm clueless (I'm a creative, not a scientist )

For reference of Latitude/Longitude, and just so we avoid the "That southern right continent there" type discussion, here's a map with the continents labeled with their names:


Thanks!
