Tropical Wave First one of the season noted on tropical dis

[NONAME]

I am wondering hoping to find out when do tropical wave start become more amplified and traversing the Atlantic and Caribbean. What I mean is when do they start crossing the Atlantic they may have convection or not but i just wonder when is it soon. Thanks.

[windycity]

I would say June,if conditions are extremly favorable,May. Right now,there is too much shear,for anything to develop ,that of course,changes from year to year,depending on the set-up.

[NONAME]

I wasnt talking about devlopment only about 9% of tropical wave devlop in to tropical cyclones. I was wondering when they start coming across to the atlantic and caribbean.

So Can anyone still anwser my ? I'd Be very greatfull

Usually starting July through September.

We had a tropical wave earlier this month. In also they start forming to a point around late may into early June. But don't expect any chance for a depression to form from one intill mid June like a few years ago.

[benny]

Tropical waves of some kind usually become evident as early as mid April. Depending on how strong the subtropical ridge is... you may be able to follow them in the deep tropical Atlantic mostly s of 10n. Typically by May they become easier (though not easy) to track. Last year had well-defined waves in May.. we'll see if this year is similar.

The earliest i noted was april 5 in 1991;last year was may02;in 1994,was june 16...
These info can be found in the TWO,and for the oldest years in the MWR revue,in an subject they called"tropical waves";in this article,the authors described the waves season of the atlantic,with their dte of passage over Barbados...Of course,the first wave may also be first described in a TWO in the part concerning the carribean réion.
Hello cycloneye,i saw the clouds rotation in your vicinity this pm,and hope you got no much rain.
Hi to all of you in this upcomming season..So long

I thought tropical waves rolled off the African coast year round. Of course, out of season, many would be extremely far south, correct?

Not trying to say that they do anything, but are they not present year-round?

[Hybridstorm_November2001]

They do. They just form, and move, along such a low latitude that they can not get the spin they need started; due to the weakness/lack of a Corialius Effect (sp?)near the Equator. That and as the line moves further North, pre season, the strong Wind Shear tends to shred 'em apart.

[Hyperstorm]

Typically, we start to see tropical waves (areas of disturbed weather that create a "wave" in the trade windflow) in late April, early May...

[CHRISTY]

yea thats true but it is still a bit to early.

[HurricaneHunter914]

Only 9%? are you sure that's right?

[NONAME]

it could be higher but i think on average 9 out of 100 wave that travel trough the atlantic become storms.

and just looking at the Nhc Tropical disscusion at 805 look like are first tropical wave is here look below

....ITCZ...

ITCZ AXIS IS CENTERED ALONG 7N11W 2N30W 1N8W 2N46W. WEAK
TROUGH/POSSIBLE TROPICAL WAVE IS EMBEDDED IN THE ITCZ NEAR S
AMERICA ALONG 49W S OF 4N BRINGING ISOLATED TSTMS S OF 5S W OF
47W. ISOLATED TSTMS ARE ALSO WITHIN 45 NM OF 4N19W.

so HUC, here is the earliest tropical wave noted for you beating out the april 5 one of 2001

[HUC]

Yes Noname,beat for one day....I will note that in my data!!!

[NONAME]

When do you think the next one will show up.

[HUC]

.
...and,the one of april 5 was in 1991,and not 2001

[HUC]

Honnestly,and withouth any of the sophisticated instuments of the TPC,very difficult to say.So,wait and see!!!

[NONAME]
