Types of Storms in the Oceans

Ocean storms are classified by latitude, energy source, and structure:

Tropical Cyclones (Warm-Core)

• Tropical Depression: <39 mph (63 km/h) sustained winds.
• Tropical Storm: 39–73 mph (63–118 km/h) – named.
• Hurricane / Typhoon / Cyclone: ≥74 mph (119 km/h) – Category 1–5 (Saffir-Simpson).

Mid-Latitude (Extratropical) Cyclones

• Nor'easters: Intense NE U.S. coastal storms (cold-core, baroclinic).
• European Windstorms: Deep lows hitting Western Europe (e.g., "St. Jude's Storm").
• Bomb Cyclones: Pressure drops ≥24 hPa in 24 hrs – explosive intensification.

Polar Lows

• Small, intense, cold-core vortices over Arctic/Antarctic waters – "Arctic hurricanes."

Other Phenomena

• Waterspouts: Tornadic or fair-weather vortices over water.
• Medicanes: Mediterranean tropical-like cyclones (rare, hybrid).
• Atmospheric Rivers: Narrow moisture plumes causing extreme rainfall (not storms per se, but storm drivers).

All redistribute heat, moisture, and momentum—key to global climate.
