为何冷洋流沿岸海域常出现海雾

Fog forms along coastlines where warm, moist air moves over cold ocean currents.
The cold water cools the lower atmosphere below its dew point rapidly.
As a result, water vapor condenses into tiny droplets suspended near the surface.
This advection fog is especially common off California and Peru’s western shores.
Satellite images clearly show fog banks hugging the coastline each morning.
Mariners rely on real-time fog forecasts because visibility can drop below 100 meters.
Unlike radiation fog, this type persists even in daylight due to continuous cooling.
Climate models predict increased fog frequency if coastal upwelling intensifies with warming oceans.
Scientists monitor sea-surface temperature gradients using buoys and infrared sensors.
Understanding this process helps improve coastal weather warnings and aviation safety.
