Gulf of Mexico - 2025 ACF Fall

Question

A current named for this body of water makes the weather of Northern Europe milder than the latitude would suggest. For 10 points each:

[10e] What body of water’s namesake “stream” drives the North Atlantic Current along with the Canary Current? Hurricane Katrina moved from the Caribbean into this body of water.

ANSWER: Gulf of Mexico [or Golfo de México; prompt on Gulf Stream; prompt on Gulf of America]

[10m] The North Atlantic current is part of a system of ocean circulation named for these two quantities, which is sometimes called the “oceanic conveyor belt.” These two quantities primarily determine the density of seawater.

ANSWER: temperature and salinity [accept thermohaline circulation]

[10h] Climate change has weakened the North Atlantic Current, allowing these winds to travel into Northern Europe and cause heat waves. These Mediterranean winds originate in the Sahara.

ANSWER: sirocco [or Ḫamsīn or Marin]
