Tropical Trio

A trio of tropical storms can be seen on this satellite image below. Former Hurricane Danielle (at top) has simply become a low pressure system now.

From NOAA: GOES-13 Catches 3 Tropical Cyclones Thrashing Through the Atlantic

Powerful Hurricane Earl, growing Tropical Storm Fiona and fading Danielle were all captured in today’s visible image from the GOES-13 satellite. The Geostationary Operational Environmental Satellite called GOES-13 captured an image of the busy Atlantic Ocean at 1145 UTC (7:45 a.m. EDT) on August 31. In the visible image, was the large and powerful Hurricane Earl passing Puerto Rico, Tropical Storm Fiona located to Earl’s east, and Danielle far in the Northern Atlantic. Hurricane Earl’s eye appear to be covered with high-clouds in the GOES-13 image, while Fiona appeared somewhat disorganized with no apparent center. Farther north in the North Atlantic Ocean, Danielle appeared more “U” shaped on the satellite imagery, although her maximum sustained winds were still near 70 mph at that time.

GOES satellites are operated by NOAA, and the NASA GOES Project at NASA’s Goddard Space Flight Center in Greenbelt, Md. provides images and animations of satellite data.

I posted this on an earlier hurricane thread….but it bears repeating…
I am amazed at how the NHC, Accuweather and others how downplayed the significance of the dry air intrusion as just an “eyewall replacement cycle”.
Eyewall replacement cycles don’t usually take 36 hours to complete.
Bastardi [I am an Accuweather Pro subscriber] was quoted a few hours ago: “An eye is forming. Its going on a true northwest course.”
Well, Joe, where is the eye? And isn’t this course a little more north than northwest [eye wobble adjusted].
The HUGE dry air blob to the northwest has been indirectly influencing Earl, for as long, and is now directly influencing him now.
He is about to gulp in a huge amount of it, and, as evidenced by the CLEAR AIR slot [is this possible in a CAT 4 storm] advecting in from the southwest.
Keep gulping, Earl.
I’d love to watch you die.

There’s a huge batch of dry air off the east coast right now as seen in the water vapor loops. If it gets to land, and that’s a big if, it will probably be a shell of it’s former self.

Wow, that’s quite a snapshot.
I wonder if Danielle is going to be responsible for the deluge predicted by Piers Corbyn between Sept 15-28 over Ireland and Britain.

Danielle may be a low now but those storm winds are still causing an awful lot of evaporative cooling. To what extent will dying hurricanes lower the higher SSTs that were showing in the more northern Atlantic? If they do it can’t help what’s coming this winter in Europe.

Check out the morning water vapor loop on your Accuweather pro site at
Is the dry air getting eroded? Remember there is a constant addition of moisture as the air hangs out over very warm seas. Also Fiona seems to have pumped a slug of moisture into the east to northeast quadrant of Earl. Is the glass half empty, or half full?
I never dare predict these things. I just watch in awe.
Best of luck, as you await things in Norfolk.
I’m gazing about the wooded hills up here New Hampshire, wondering how wooded they’ll be on Sunday. Carol pretty much scalped our hills back in 1954, but no one around here remembers, and there’s some pretty nice houses up in those hills now.

I can’t remember how long it takes the residue of a hurricane to reach the UK but I would have thought Danielle would be long dead by 15th. She is more likely to whip up a bit of a breeze in the next week perhaps.
Great picture!

Was that Danielle that caused the growing blue spots showing up in the SST?

September 1, 2010 8:55 am

SavetheSharks, right on: it is the MPH that gives hot temperatures over the eastern sea board that has pushed Danielle over.
Cyclone trajectories can be well estimated through understandng lower layers dynamics: “Dynamci analysis of weather and climate” Leroux, Springer 2010 2ed. chap. 11.

Would have thought that The Great Danielle would have had a bigger impact on the British Isles and Northwestern Europe. Say la Vie!

The HUGE dry air blob to the northwest has been indirectly influencing Earl, for as long, and is now directly influencing him now.

Why do you say ‘dry air’ – given the temperature of this air mass from the WV imagery, I judge that to be about 20,000 foot altitude … so, dry air exists above 20k feet. (WV imagery would seem to indicate the temperature of the *highest* air mass with WV (wator vapor, not condensate) present; pls correct me if I am wrong.)
I would think warm, moist air to 20k feet would be sufficient for ‘feed stock’ to keep a series of T-storms active (unless they were really high-based T-storms!) e.g. exist in a hurricane.

Notice what seems to be -11 to -13 C ‘air’ to the south/SSW and (earlier) wrapping almost completely around the storm’s cloud mass …

So, what will be the effect of Danielle’s circulation pattern as it crosses the GIUK gaps up in the North Atlantic around Iceland?
How will its wide pattern of (lower but still effective) counterclockwise winds affect Arctic ice coverage – and will any warmista acknowledge its (potential) affect on ice extent?

From 1745z 9-01-2010 – Note the ‘warm’ air intrusion.
Temps according to scale appear to be -12 to – 18 degree C range. This translates to 18 to over 20,000 feet according to the ‘chart’ above (tropospheric lapse rate for JJA time frame).

Well so much for the dry air. Caleb and _Jim you are right.
Concerned very much now that the cyclone might be edging toward a CAT 5.
Unheard of at this latitude.
And Caleb, I am getting increasingly concerned for New England. The interaction with the trough and such an intense hurricane as Earl might really be a problem.
Bastardi likens this one more to Edna and not Carol, however….but holy smokes this is ONE intense storm….
You can see the stadium effect in the eyewall. Reminds me of K….. Ka……. Kat…..
I don’t want to utter the name because she was such a bitch.

The passing hurricanes have indeed lowered the SSTs (which are actually at a record level in the tropical-mid-Atlantic right now). It looks like Danielle is mostly showing up now while Earl hasn’t been arounf enough yet to show up.
Not a large area affected but certainly on a localized level, Danielle turned a +2.0C ocean into a -3.0C one.

Hi-res global ocean current animation which is actually pretty interesting.
