I'm looking for a realism check on the climates of a Eurasia-like continent situated mostly in the tropics. I want to maximize tropical rainforests, savannahs, and hot semi-arid climates.
I asked advice on a previous version of this Earth-like world here. Since then, I've reworked the big equatorial continent, breaking up mountain ranges and introducing a lowland belt strung with shallow seas along the width of my big equatorial continent in order to create contiguous savannahs and rainforests.
Here's my climate map: Note that I've marked out areas above 1000, 1500, and 2000m because it's important to know where they are due to their rain shadows and because I'm less sure how to apply climates to them. The climates I've put in these regions can be considered tentative. Also note that ocean currents deflect in unusual ways in several places because of sunken continents just under the surface.
Is my desert too small?
Given the rain shadows caused by the high mountains and the large plateau, the presence of warm and cool ocean currents on either coast, and the relative lowness of the area around the shallow inland seas, have I struck the right balance between aridity and humidity? Would my plateau be this dry considering its height (average of 1100m), would the desert extend all the way to the western archipelago as I've drawn it, and could enough moisture feasibly reach this far inland to make such an extensive rainforest--or should the savannah be predominant? To the East, I'm aiming to have a region like the Brazilian savannah, with arid highlands where the mountains come down to about 1000m. Is this realistic, or are my mountains too high there?
