2006 Hurricane season cancelled by African dust

In the spirit of Professor Tyndall

Why were there so many hurricaines in 2005, and then virtually none in 2006? According to predictions including sea surface temperatures, it shoudl have been a killer. A recent article in Science reports that an enormous dust cloud from West Africa blew across the Atlantic in June 2006, the beginning of the hurricane season. After about two weeks sea surface temperatures began to cool, relative to temperatures in 2005. The cooling lead to a shift in weather patters that was less favorable for hurricane formation.

It is interesting that 3-Speed thought I looked like Professor Tyndall, a prominent Irish professor in the 19th century. He was the first to show that gases like carbon dioxide and water vapor absorb infrared radiation (1860s), and linked this behavior to the ice ages.

About the photo:

I searched Google for a photo of a professor. When I saw Tindall's photo, I laughed so hard I spit on my keyboard. Each time I clicked the link, I laughed.

I thought others would laugh too, but inlines are allowed from Gutenberg. I should have known. Sorry.

Why don't you email me the picture and I will post it--
