Conversely, the eastern North Pacific is relatively quiet regarding landfalling hurricanes. These events are usually the remnants of Pacific hurricanes that have weakened significantly over cooler waters but still retain enough moisture to cause significant weather events.
How Cold Water and Wind Shear Shield the California Coast
Unlike the East Coast, which sits adjacent to the warm Gulf Stream current, the West Coast is dominated by cold currents like the California Current that chill the ocean surface year-round. The Double Whammy: Cold Water and Shear It is the combination of these two factors—cold sea surface temperatures and high wind shear—that creates an almost insurmountable barrier for hurricane formation off the West Coast.
Wind shear refers to the change in wind speed or direction with height in the atmosphere. The few systems that do approach the West Coast tend to dissipate over the cold waters long before reaching the shore, serving as a powerful visual representation of the ocean's critical role in our planet's weather systems.
How Cold Water and Wind Shear Shield the California Coast
The tropical eastern Pacific often experiences high levels of wind shear, which dismantles any potential hurricane before it can mature into a major threat. The vertical alignment of a storm is crucial for its development; strong shear can tilt the storm's core, disrupting the circulation and preventing it from organizing.
