GreenTracker| In a startling new computer model, scientists predict that an ocean’s color has direct impact on the development of hurricanes. We think of the oceans as blue, but they are a greenish color, depending on the amount of cholorophyll in the water.
One study finds that hurricane activity drops by 70 percent, in a region that accounts for more than half the world’s reported hurricanes. As the amount of cholorophyll declines — driven by global, declining phytoplankton populations — the average amount of hurricane activity should decline. Local conditions will have impact.
In the no-chlorophyll scenario, sunlight is able to penetrate deeper into the ocean, leaving the surface water cooler. The drop in the surface temperature in the model affects hurricane formation in three main ways: cold water provides less energy; air circulation patterns change, leading to more dry air aloft which makes it hard for hurricanes to grow.The changes in air circulation trigger strong winds aloft, which tend to prevent thunderstorms from developing the necessary superstructure that allows them to grow into hurricanes. via Science Daily
