Lunar cycle can turn hurricanes into monsters

Washington, March 6 (ANI): A new study has determined that hurricanes strengthen more often under a new lunar cycle than at any other time.

The moons strange influence on Earth and its denizens is legendary. From fertility to suicide, most phenomena attributed to the Moon are almost exclusively superstition.

But, according to a report in Discovery News, Peter Yaukey of the University of New Orleans has found what he thinks is real evidence that the phases of moon drive hurricane behavior.

Storms that occurred in the Atlantic Ocean between 1950 and 2007 were more likely to form right after the new moon.

They also intensified 49 percent more often after a new moon than at any other time in the 29.5-day lunar cycle.

Over the last century, a smattering of scientific research has hinted that the moon may influence rain patterns, thunderstorms and other meteorological events, Yaukey said.

Explanations for why this is are many, but nothing conclusive has been shown.

I had a lot of skepticism attributed to the moon, and I still do in a sense. Its not enough to have a pattern in the data. You need to have a mechanism to explain it, said Yaukey.

There are a range of possibilities.

Just as the moon pulls on Earths oceans and creates the tides, it also tugs on the air above it. Lunar atmospheric tides are thought to be weak, but could create favorable conditions for storms to strengthen.

The moons gravity may also pull cosmic dust into Earths atmosphere in a cyclical fashion, perhaps seeding cloud formation and precipitation.

The most promising explanation is internal tides encouraged by the lunar cycle.

The currents beneath the ocean surface could circulate warm water up underneath a storm, supplying it with the energy it needs to intensify.

But before scientists seek explanations for the connection they must make sure its real, according to Gabriel Vecchi of the National Oceanic and Atmospheric Association in Princeton, New Jersey.

Theres an easy way to do an independent test for this. Go back and look back at Atlantic hurricane data from 1878-1950 to see if theres still this pattern, he said.

Only 13 percent of the worlds hurricanes occur in the Atlantic Ocean. So, if the moon is really influencing hurricanes, the signal should show up in Pacific and Indian Ocean storms, too. (ANI)
