So the thermonuclear devices detonated near the sea surface were in the ballpark of 10Mt. At least half of the yield (probably more due to reflection) went up into the atmosphere. I'm curious if a more powerful weapon (Russia's Tsar Bomba had a yield of 50Mt, with a theoretical limit of 100Mt), detonated below the sea (so that all/most of the energy heats up water) could achieve a hypercane, or if it's just a drop in the water (pun intended)
