Large wave in Central Atlantic

[HurricaneHunter914]

Out of the SAL and into the increasing shear. I'd give this system a low chance at development. I think we're in for a long lull.
Then again, if it can make it into the Caribbean. I think there might be some potential.

Sorry guys... newbie here... what does SAL stand for and what about it makes it prohibitive for development of a wave?

thanks,

This should take you to the Tropical Reference Library.

Storm2k's very own reference library of links, terminology and basic storm information.

I go there often and there is a list of acronyms.

SAL = Saharan Air Layer

Basically its a giant layer of dust from the Saharan Desert. It makes the air in the middle of the atmosphere really dry which prevents thunderstorms from developing.

Thanks for the help, I will go and do some digging... also found this on Wikepedia

Here is the whole explanation about what the Saharan Air Layer is (SAL)

Some decent convection happening with this one.

..TROPICAL WAVES...

AN ATLANTIC OCEAN TROPICAL WAVE IS ALONG 32W/33W SOUTH OF 20N
MOVING WEST 10 TO 15 KT. NUMEROUS STRONG SHOWERS AND
THUNDERSTORMS FROM 8N TO 10N BETWEEN 34W AND 36W.

AN ATLANTIC OCEAN TROPICAL WAVE IS ALONG 47W SOUTH OF 15N
MOVING WEST 10 TO 15 KT. NO PRECIPITATION ACCOMPANIES THIS WAVE.

A TROPICAL WAVE IS ALONG 28N65W 23N66W 16N67W 9N67W MOVING WEST
15 KT. A 1012 MB LOW PRESSURE CENTER IS ALONG THE WAVE NEAR 20N.
STRONG SHOWERS AND THUNDERSTORMS IN A SMALL AREA WITHIN A 15 TO
30 NM RADIUS OF 22N61W. CONVECTIVE DEBRIS CLOUDS AND POSSIBLE
LINGERING PRECIPITATION FROM 20N TO 27N BETWEEN 54W AND 63W.
HIGH CLOUDS ARE BEING BLOWN TO THE NORTH-NORTHEAST FROM 27N TO
32N BETWEEN 52W AND 58W. SHOWERS AND THUNDERSTORMS ARE SOUTH OF
16N EAST OF 70W...AND FROM 17N TO 20N BETWEEN 63W AND 66W.
THE WAVE HAS BROUGHT PRECIPITATION MAINLY TO THE SOUTHEASTERN
CORNER OF THE CARIBBEAN SEA.

A WESTERN CARIBBEAN SEA TROPICAL WAVE IS ALONG 88W SOUTH OF 23N
MOVING WEST 15 KT. THIS WAVE IS MOVING TOWARD AN AREA THAT
IS TO THE EAST OF A SOUTH CENTRAL GULF OF MEXICO TROUGH.

...THE ITCZ...
13N16W 10N23W 12N32W 10N40W 11N47W 10N61W. STRONG SHOWERS AND
THUNDERSTORMS ARE FROM 8N TO 9N BETWEEN 40W AND 41W...AND WITHIN
30 NM ON EITHER SIDE OF 9N BETWEEN 46W AND 47W. ISOLATED
MODERATE SHOWERS AND POSSIBLE THUNDERSTORMS FROM 4N TO 14N
BETWEEN AFRICA AND SOUTH AMERICA.

I edited the title to not have confusion about the waves and the threads.

[catastrophic]

still got some good convection and its aboout to head in to a better enviorment shear wise



the area of convection is where the pink circle is and it is about to move into an area of less shear

Lol sorry but you have it in the wrong spot. Thats 20N, not 10N

[catastrophic]

then its heading into the shear

[Patrick99]

Sometimes I think a SAL can actually increase the chance of a US landfall. Keeps waves fairly weak and low instead of spinning up and out right away as they sometimes do without a SAL surge. If SAL doesn't kill a wave off entirely, the wave can move into a more favorable environment closer to home and get something going.

The TAFB now shows this wave as a low in 24 hours and back to a tropical wave in 72 hours.

Any models on that?

[Blown Away]

Maybe for now, but if this wave holds together overnight I give it a high probability of being an invest tomorrow. Also, the TAFB has this wave breaking away from the ITCZ as a low near 11N/40W in 24 hours. This is our next player IMO.

[cycloneye]

Tropical wave is relocated back in longitud.From the 8 PM Discussion.

A TROPICAL WAVE IS RELOCATED ALONG 31W SOUTH OF 20N BASED ON
SATELLITE IMAGERY THAT SHOWS A CLASSIC INVERTED V-SIGNATURE AND
THE TPW PRODUCT FROM CIMSS WHERE A BULGE OF MOISTURE IS NOTED
ALONG 31W. CYCLONIC TURNING IS ALONG THE WAVE AXIS NEAR 16N WITH
ISOLATED SHOWER ACTIVITY. 850 MB SATELLITE DERIVED VORTICITY
ALSO SUPPORTS THE POSITION OF THE WAVE.


The blob is part of the ITCZ.

...THE ITCZ...
ITCZ AXIS IS CENTERED ALONG 12N16W 11N29W 10N35W 10N46W 10N62W.
A LARGE CLUSTER OF MODERATE TO ISOLATED STRONG CONVECTION COVERS
THE AREA FROM 7N-11N BETWEEN 34W-37W. SIMILAR CONVECTION IS NEAR
8N43W. SCATTERED MODERATE CONVECTION IS WITHIN 40 NM EITHER SIDE
OF WAVE AXIS BETWEEN 50W-55W.

...This is our next player IMO.

Normally, I would dismiss a flare up of convection in that area as just the ITC doing its thing and figure it would simply diminish with time. But this is August and climatology dictates that we should keep a careful eye on that region.

Blown-away, I suspect this could be a player down the road but I'm not willing quite yet to go out on a limb and say that it will be.
