cyclonebuster Posted July 3, 2012 Share Posted July 3, 2012 Sigh, this thread is a trainwreck....it is only July 3rd, one should expect hostile conditions in the MDR and we know from past experience that atmospheric conditions in this area can change on a whim. We will have an entire month to formulate one storm, which would fulfill the monthly historical average. Perhaps some more homebrew in the future as well, who knows...? The post about insufficient SST's was total bs. I knew I was right at least 2C above the mean..... Link to comment Share on other sites More sharing options...
am19psu Posted July 3, 2012 Share Posted July 3, 2012 Adam, Also, I believe that there may be a partial positive correlation between El Nino and SAL frequency/concentration in the MDR. Have you researched this? I'm unaware of any research in this area, though I've noted the same thing anecdotally. Link to comment Share on other sites More sharing options...
Riptide Posted July 3, 2012 Share Posted July 3, 2012 And shear will increasingly be an issue as the Walker circulation is disrupted due to the developing Nino, plus relative SSTs still suck. It's true that SST's are not relatively warm because it is early July, but it's not worth mentioning because if you extrapolate it into the future; it would argue for a continuation of above average or average SST's.

Relative SSTs means the difference in the SSTAs in the subtropics and the tropics. When the subtropical SSTAs are warmer than the tropical SSTAs, it's bad for MDR cyclogenesis.

This is interesting but would a higher temperature anomaly be more easily achievable in the subtropics because it is farther away from the equator? It seems that temperatures in the tropics and subtropics are roughly the same temperature right now. Link to comment Share on other sites More sharing options...

Correct and the shear is low right now,also. Warm SST's and low wind shear a recipe for disaster when talking hurricanes. Link to comment Share on other sites More sharing options...

am19psu Posted July 3, 2012 Share Posted July 3, 2012 And to Steve's point elsewhere, this doesn't mean that tropical activity as a whole is going to be nil. It'll just be closer to home, in the Caribbean, Gulf, or SW Atlantic. But the MDR is not going to be the place to look this year. Link to comment Share on other sites More sharing options...
Riptide Posted July 3, 2012 Share Posted July 3, 2012 The difference between subtropical and tropical SSTs is minimal at best, though I suppose there remains some negative factor in regards to TC genesis. Link to comment Share on other sites More sharing options...

Bryan Wood Posted July 3, 2012 Share Posted July 3, 2012 I'll bet you one Whopper one Large Fry and Chocolate Milk Shake it is.......... Probably not. You'll see a lot of "open" waves move towards the Caribbean, where the environment will be somewhat better for development. There will be chances for MDR development, but it won't be gangbusters like 2004. I highly recommend you take the advice of others and read some of the peer review papers listed in this thread. There is much to learn about the SAL. Link to comment Share on other sites More sharing options...

Sunny and Warm Posted July 3, 2012 Share Posted July 3, 2012 Did I say gangbusters? Of course not. I am like you there will be chances...... chances yes. However, I've seen many a Cape Verde season go stillborn due to SAL. It can be difficult to extinguish once established as a seasonal trend.

Ed Lizard Posted July 3, 2012 Share Posted July 3, 2012 I have seen the Sal squash them also. But that air is rich with moisture this year not like past years especially in the ITCZ.... Once beyond the ITCZ, not so much. Check the EastPac for comparison. Note also where drier air is coming from, and there is a SAL analysis from today from the CIMSS website uploaded previous page. ETA- also noted by others- a slow MDR might mean relatively more development closer to the US, and as the famous Joe Bastardi used to note (and probably still does) Cape Verde storms usually miss the US, storms forming in closer have a relatively greater chance.

PSUBlizzicane2007 Posted July 4, 2012 Share Posted July 4, 2012 The definition of stupidity is doing the same thing over and over again and expecting a different result. Every year, people are complaining about the SAL, shear, dry air, lack of storms, etc. etc. in May/June/July as if there is supposed to be pristine TC formation conditions during that time. Enough already. Link to comment Share on other sites More sharing options...
