Why Paris Is Milder Than Fargo at Same Latitude: Ocean Currents

Latitude determines solar angle, but climate is shaped by heat transport. Paris (~49°N) and Fargo (~47°N) differ because:

• North Atlantic Drift (Gulf Stream extension) carries warm subtropical water to Western Europe, releasing heat into westerly winds that bathe Paris.
• Fargo sits in the continental interior; no oceanic moderation. Arctic air masses plunge south unimpeded, causing extreme cold (–30°F possible).
• Prevailing westerlies bring maritime mildness to Europe; North America's westerlies cross the Rockies, losing moisture/heat, then deliver continental extremes.

Result: Paris January avg 5°C (41°F); Fargo January avg –12°C (10°F).
