Tammy and new wave update

Tammy took off to the north like a rocket, made landfall, and is raining in Georgia.  There's another wave, which broke off from Stan, and is headed in our direction; and there's an upper level low in the Gulf, which used to be connected to the tropical wave that became Tammy...  Weather is certainly unpredictable.  Oh, there's another wave off Africa.

I was reading a science news story the other day that I really have to track down.  It was about research to discover what makes an ordinary weather front coming off Africa start to spin and so become a potential hurricane.

The researchers were happy to note that a great many of these fronts from Africa went clear across to the Pacific ocean before spinning, and thus became Eastern-Pacific typhoons instead of Atlantic hurricanes.

I always wondered where typhoons came from if hurricanes come from Africa.  They can come from the same place!  It all depends on what exactly it is that makes the front start to spin counter-clockwise. Bumping into another front?  An especially warm or cold water area?  Martians?

Anyway, by having just the west coast of Central America to look at for the cause of spinning, instead of the entire Atlantic Ocean and the Caribbean, the researchers were hoping to pinpoint the cause of spinning more clearly.

oino,

Thank you!  I hadn't heard about that.  Watching those waves approach gives you plenty of time to speculate.  In the old days we didn't have that chance; people depended on barometers, and I saw in a documentary that the devastating hurricane that struck New England registered on the barometer, but apparently one person at least thought the barometer was broken.  Couldn't he check others?  What about everyone else's barometers?

The great advantage we have in this century over even just a couple of decades ago is how easy it is to spread information or find out what we want or need to know.  Alas, that includes rumors and trivia and gossip.  But it's a lot easier to check on other people's barometers now-- or just check the National Weather Service on the Internet-- while the wind allows :-)

Wave off Africa is Vince?

MIAMI — Tropical Storm Vince (search) formed Sunday in the far eastern Atlantic, making this hurricane season the second busiest on record, forecasters said.

But the storm, which had top sustained winds of about 50 mph, poses no threat to land. That's because it wasn't expected to survive for long due to the cooler waters and other weather systems in the area, Sisko said. Water temperatures are about 73 to 75 degrees, below the 80 degrees usually needed for a tropical storm.

At 11 a.m. EDT, Vince's center was located about 515 miles east-southeast of the Azores and about 140 miles northwest of the Madeira Islands. It was moving northeast at about 5 mph.

oino,

Vince?!  I don't know which wave became Vince.  Must find out.  Thanks!
