# What is the climate of an otherwise ocean planet with a huge landmass along the equator? [closed]

I am coming up with a new planet idea inspired by One Piece. I'm imagining a planet with the same mass, volume, and sunshine as Earth. The difference is that it is mainly an ocean planet. There are no large continents. Instead, there are thousands of islands spread across the planet that are roughly the size of Jamaica. The one exception is a huge mountainous continent in the center. Along the entire equator is a huge landmass that stretches 500 km both north and south. This landmass is filled with mountains but it also has many plateaus and a few jungles plus rainforests. This equatorial continent effectively cuts the planet in two; leading to two completely separate oceans. There is almost no land at the poles.

So given these conditions, what is the expected climate of this world? I think there would be conditions similar to the Pacific Ocean in both halves but the climate on each island could vary.

• Humanity knows about the climate of one habitable world - Earth - and we have trouble predicting tomorrow's climate, and you want a hard-science analysis? Answers that fail to conform to its rules are under threat of deletion. Answers are required to provide mathematics and citations to prove the answer. I don't know what you expect us to draw from to prove the climate of an imaginary world when we have only one datapoint to work with. Maybe your expectations are a bit high? Consider science-fiction and this answer.

• You haven't provided nearly enough detail to hope for a hard science answer; how are these Jamaica-sized islands distributed? What shape does the equatorial continent take? Where are the continental shelves? Any insland seas of note? Mountain ranges?

• ".. a huge mountainous continent in the center". Of a continuous line? Or of a sphere? Where, pray tell, is that, exactly? :D Mar 21 at 10:30
