NASA satellites provide infrared images to forecasters that show temperature, and today's imagery of powerful Hurricane Igor showed the storm's perfect form and the warm ocean waters around it that are keeping it fueled. NASA's infrared data also revealed a huge difference of 170 degrees between the cold cloud tops in Hurricane Igor and the warm sea surface temperatures powering it below.
When NASA's Aqua satellite passed over Igor on Sept. 14 at 14:47 UTC (10:47 a.m. EDT) the Atmospheric Infrared Sounder (AIRS) instrument captured icy cold cloud top temperatures in the strong thunderstorms that surround Igor's well-defined eye. Those cloud top temperatures were as cold or colder than -90F, indicating they were near the top of the troposphere, and very strong.
The infrared imagery also showed the warmer, open 20 nautical-mile wide eye (because it was not cloud-filled). In addition, AIRS got a reading on the sea surface temperatures around Igor, which were all warmer than the 80F threshold needed to maintain a tropical cyclone, so Igor has a good energy source for the next day or two. So, the difference between Igor's cold cloud top temperatures and the warm ocean surface waters that are powering it are greater than 170 degrees Fahrenheit!
The AIRS instrument is managed out of NASA's Jet Propulsion Laboratory in Pasadena, Calif. and NASA's Ed Olsen creates those stunning images.
At 11 a.m. EDT today, Sept. 14, Hurricane Igor was still a category 4 hurricane on the Saffir-Simpson scale with maximum sustained winds near 135 mph. It was located far from land, about 710 miles east of the Northern Leeward Islands, near 18.3 North and 52.3 West. It was moving west-northwest near 7 mph, and is forecast by NOAA's National Hurricane Center to turn toward the northwest on Wednesday. Igor's minimum central pressure is 945 millibars.
Although Igor is over 700 miles from the Northern Leeward Islands, large ocean swells will reach them today creating dangerous conditions at beaches. Large swells will reach Puerto Rico and the Virgin Islands later today and tomorrow. These dangerous surf conditions also create rip currents along the beaches.

Well, based on that pic, I’d say we’ll soon be calling it Eyegor.
Isn’t the standard lapse rate 3 degrees per thousand feet, so *IF* we go from say 85 degree F water temps to MINUS 85 degrees at the cloud tops ... and presume we have cloud tops in the purple at the FL 550 ... that means we need to drop 170 degrees F in 55,000 feet for a lapse rate of OMG 3 degrees per thousand feet.
OMG it’s a monster storm!!!
sarcasm off.
I wonder which Muslim invented this AIRS system for NASA. I’ll call the White House and find out.
Been centuries sine any moosie turd invented anything.
I say, fake—everyone knows the ocean doesn’t glow orange.
OMG! A Standard Atmosphere! How can that possibly be with all the globull warming going on? Run for your life!
Been centuries sine any moosie turd invented anything-
They live in their own litter boxes.
I HATE the 24 hour news cycle, every little blip has to mean the end of the world.
Film at eleven.
That is quite a front moving in!
LOL! Mission Control is probably filled with Islamic prayer rugs now. NASA was good when the Germans ran it.
What the hell is NASA doing monitoring hurricanes?
Aren’t they supposed to be a muslim outreach organization?
Well, I guess there is a connection there.
Hurricanes and Muslims cause massive damage and death.
Ok, Now I am with the program.
They invented Muslim Body Armor.
Also known as “woman and children”.
Hump?
What hump?

Thanks for that explanation. I was kinda trying to work it out and (brain fizzle)-— you got it.
Her footwork is all wrong for that punch.
