...decades have been well documented, the reasons for them remain obscure. That's not the case for individual storms, though. Atlantic hurricanes inevitably get their start in Africa, where hot, dry air overlying the Sahara desert collides with cooler, moister air over the sub-Saharan region known as the Sahel. Under normal conditions, the collision produces eddies of low-pressure air that drift out over the ocean, where storm clouds begin to form. Most of the time, the clouds simply dump their load of rain and dissipate...
...terrible, two-decade drought that plagued the African Sahel until lately also cut down on tropical storms, says Gray. Strong winds that accompanied this prolonged dry spell swept rain clouds away from the Sahel and sheared the tops off storm systems that might eventually have become hurricanes. Now that the drought has eased, these storms are more likely to persist and grow...
...Great Ocean Conveyor Belt, a vast, and so far poorly understood, undersea current that carries warm water from the Pacific and Indian oceans into the Atlantic. When the conveyor belt runs faster for unknown reasons, there is more warm water available to generate both rain in the Sahel and storms over the North Atlantic. Or so the reasoning goes...
...even though nobody has a handle on the underlying dynamics, the link between far-flung weather patterns and the North American hurricane season appears solid. Indeed, for the past 12 years, Gray has routinely used El Nino, Sahel rainfall and other factors to make impressively accurate predictions. Last October he forecast 12 major tropical storms for 1995, and in early August he upped the number to 16, just five storms shy of the record set in 1933 and more than double the number in 1994. "People thought we'd gone crazy," says Gray. "Now it appears we probably undershot...
Deep Forest was conceived by Michel Sanchez and Eric Mouquet, two French musicians who blended New Age electronics with UNESCO field recordings of music from Zaire, the Solomon Islands, Burundi, Tibesti and the Sahel...
