The Critical Role of Sea Surface Temperature Hurricanes are essentially heat engines that require water temperatures of at least 80°F (26. The absence of hurricanes striking the West Coast of the United States, while the East Coast regularly faces these massive storms, is a question rooted in fundamental oceanography and atmospheric science.
Why the West Coast's Ocean Currents and Wind Shear Block Hurricanes
This current acts as a thermal barrier, preventing the formation of the warm, moist air masses needed to trigger the cyclonic rotation associated with hurricanes. This eastern boundary current flows southward along the western coast of North America, originating from the cooler waters of the North Pacific.
The North Atlantic is a hotbed of activity, with storms tracing predictable paths toward the Caribbean and the eastern United States. This warm water provides the fuel for the storm through the process of evaporation.
