Since I was a child, I've always thought that the word "climate" only defined as the air that just above the landmass, why it can't be above the water? If so, the climate will like Maldives, Midway or Attu Station? I think it would be interesting!
p.s. I've always dreamed about a "Global Surface Climate Classification" map, The recent one seems incomplete for lacking ocean areas.

Maps like this (this is Trewartha by the way) exist, but they aren't always easy to find. I downloaded this on an old laptop 8 years ago from somewhere

Wow! That's amazing for such a map like that, but it looked like a little old, Don't know why this concept perished in recent days?

I don't think it went away, I think it's just that people aren't as interested in climates over the sea. They're more difficult to measure too. Rainfall isn't as relevant as there is no agriculture and no terrestrial biospheres, it will have an influence on seawater salinity but the differences produced between say a hot desert and tropical rainforest climate over the sea won't be nearly as noticeable.

Well...it can't be that old ...it shows Ukraine as a country ...not part of the USSR

Really cool map...amazing how sharp the ocean climate boundaries are in the far siuthern oceans
near Antarctica.

Yeah, maybe knowledge just served for people's benefit on most circumstances, yet "SSC" is as important as "LSC" (or more) in my opinion. Given that sea surface takes 2X more surface area than land surface.

Also doesn't have South Sudan so it has to be from the 90s or 00s.

Yeah the transition between 8 months >10 C (this is Trewartha) and 0 months > 10 C occurs within a 5-degree band between the longitudes of South Africa and westernmost Australia, with the area between [the longitudes of] South Africa and Madagascar being especially sharp and close to the equator.

It looks as though the closest to the Equator is in the south central to south east Atlantic, but the sharpest gradient is in the south east Indian Ocean. It's probably linked to tropical climates extending especially far south in that region, which probably leads to reduced seasonal variation in temperature and therefore the 8 months >10C and 0 months >10C limits being close together.

There are a few odd things in this map though, such as rainforest and desert climates directly bordering each other in the central Pacific and north east Indian Ocean.

The map uses a generic BM category instead of BS and BW across oceans, not really sure why. I assume the B climates bordering Af climates thing is a quirk of Trewartha’s A climate classification.

One thing that I wonder is how climates work UNDER the sea...
