TIL about the sverdrup:

“As a consequence, the resulting Gulf Stream is a strong ocean current. It transports water at a rate of 30 million cubic metres per second (30 sverdrups) through the Florida Straits. As it passes south of Newfoundland, this rate increases to 150 sverdrups.”

https://en.wikipedia.org/wiki/Gulf_Stream

“In oceanography, the sverdrup (symbol: Sv) is a non-SI metric unit of volumetric flow rate, with 1 Sv equal to 1 million cubic metres per second (264,172,052 US gal/s).”

    @davidsuculum @gregeganSF - who is this guy Sverdrup?

    "During 33 expeditions with the research vessel E. W. Scripps between 1938 and 1941, Harald Sverdrup produced a detailed oceanographic dataset off the coast of California. He also developed a simple theory of the general ocean circulation postulating a dynamical vorticity balance between the wind-stress curl and the meridional gradient of the Coriolis parameter, the Sverdrup balance. This balance describes wind-driven ocean gyres away from continental margins at western boundaries."

    Ugh, I should learn this physics! I never achieved my goal of learning meteorology and climate science.

    @gregeganSF The gallons per second parenthetical feels a bit silly, I have to say. :)

    @irving @gregeganSF Should have been cubic furlongs per fortnight or something.

    I was just watching a video yesterday where I learned about it too! Did you see the same one?

    @EverydayMoggie No, I just looked up those articles a few minutes ago because Sabine Hossenfelder was complaining about journalists confusing the Gulf Stream and the AMOC.
