10:30 EDT TWO, TD FORMATION IS POSSIBLE IN A DAY OR TWO

[Scorpion]

Never.

[bayoubebe]

Never.

Is it possibile?

[Wnghs2007]

Is it possibile for two tropical systems to join as one?

Has that ever happened?

No its never has and never will unless the laws of physics change....

[HURAKAN]

Is it possibile for two tropical systems to join as one?

Has that ever happened?

When one gets close to another they begin the Fujiwara dance, basically both start to rotate and start to weaken, usually the stronger kill the weakest and absorb the moisture. But they don't join that easily, one must die!

[bayoubebe]

Thanks guys for the explanation. Very interesting.(especially to a very,non-pro weather gal).

[mvtrucking]

This may sound kinda stupid but do you guys remember the movie Starship Troopers? When they were on the planet with all the bugs, the troopers were on this command station lined up and all of a sudden a million bugs came charging right at them and one of the leader troops was like "Here we go!!" Well I guess it feels a little bit like that cause these tropical systems are gonna come at us like crazy.

<RICKY>

Loved that movie Ricky.....Crazy season for sure

[Wthrman13]

Never.

Sure it is. It just depends on what you mean by "join as one". If you mean joining together into a bigger and stronger tropical cyclone, then no, but if you mean two tropical cyclones coming so close together that one circulation is absorbed into the other, then yes, it is possible and has occurred on occasion (although it certainly isn't common). Virtually always when this happens, the weaker storm is torn to shreds by the strong shear on the outer fringes of the stronger storm. I recall one such unusual case a few years ago in the East Pacific, where you could actually track the low level circulation of the weaker storm for quite a while as it gradually spiraled in toward the stronger one.

Last year, it kind of happened with Lisa.
Another disturbance followed it very closely and was absorbed the bigger Lisa.

[Matt-hurricanewatcher]

That distrabance/Depression was much bigger then Lisa. Lisa was a very small storm. That system had T numbers with quickscat support for two days before the two systems joined together. That system took the energy that was Lisa. In that system was a new system I think...Why because a new area of low pressure took the energy...I don't know how it was still called Lisa. About the same thinking for Ivan 2#.


Also for 99L it looks to be forming a area of convection over the LLC. If the LLC is under that we are very close to having a depression. I'm waiting for new Quickscat data/T numbers.

[Matt-hurricanewatcher]

99L is now a 1.5/1.5 which means it is close to a depression. It appears to becoming better oreganized. With a large area of convection over the LLC. Expect when or if the new quickscats show a LLC a upgrade.

[Hurricaneman]

wow, this season is nuts

[HurricaneJoe22]

thanks, Capt. Obvious

[Matt-hurricanewatcher]

Not more nuts then 1933 or 1995 or 1886 when 4 hurricanes hit Texas with in one month??? Its a normal active period. In believe me it is likely this was/is not the most active of them over the last thousand years.(Thats a guest)


If you went to start thinking...1995/1933 may not even make it into the top 10 over the last 500 years.(If there was a record)

[Hurricaneman]

I would think Matt is right, we go through cycles with active and inactive periods, and we dont know much before 1885
