WASHINGTON (AFP) – A change in the color of the ocean could dramatically impact the number and intensity of hurricanes, according to US researchers.
A team of researchers with National Oceanic and Atmospheric Administration (NOAA) ran computer simulations of such a change in the North Pacific, a region that accounts for more than half the world's hurricane-force winds.
The main factor is the green tint ocean water takes when there are large concentrations of chlorophyll, a pigment that helps tiny organisms known as phytoplankton convert sunlight into food for the rest of the marine ecosystem.
"We think of the oceans as blue, but the oceans aren?t really blue, they're actually a sort of greenish color," said lead reseacher Anand Gnanadesikan in a statement released Friday.
"The fact that [the oceans] are not blue has a [direct] impact on the distribution of tropical cyclones," Gnanadesikan said.
Without chlorophyll, sunlight penetrates deeper into the ocean, leaving the surface water cooler.

The sky is not really blue either , yaknow, it’s more a gray..

I don't see any green.
Food Coloring: It's not just for baking./s
The sky REALLY doesn’t have a color. What we see is an optical illusion given off by refracted light from the Sun. At night, you see what color the sky really is.
Sky has no color. The blue we see is the blue light wavelength getting through or around the atmosphere molecules in greater quanties than other colors of sunlight.
This ocean color thing could be a backdoor trick, because just the other day the Greenies were saying the plankton was dying. Plus they had to cook up something to splain why all their doom and gloom “worst hurricane season in history” predictions are not proving out.
Like mama told us, “you tell a lie and then you have to tell 5 more to cover the first one and 5 more to cover them and before long you can’t remember what was the truth”. The Globull Warmers can’t remember what the truth was.
Sounds racist to me.
If you’ve ever been crushed by mid-ocean swells, I agree with Pink Floyd’s “as a matter of fact, it’s all dark”.
Closer to the equator the sky is more grayish due to moisture content, but way up north in the dead of winter the sky gets a very rich blue.
Actually they are colorless. If what you were saying were true, the sunset would be blue. The blueness of the sky comes from the scattering of light by the air, which affects higher frequencies preferentially. The blue that you see is light that was initially going a different direction. The sunset is reddish because it is seen through more air than the noonday sun, and the blue frequencies are scattered away from your line of sight.
Of course they are.
Their colors are determined by the degree of diffraction of incoming light.
That's what color is all about.
In the following graphic, picture the nitrogen and oxygen molecules as diffracting white light toward the blue end of the spectrum.
Everything has an index of refraction that fits somewhere in the spectrum.
That's what causes it's observed color.
Doesn't matter what color it's supposed to be...the only color that counts is the one you actually see.
