Hurricane Irene Banter Thread

I know it isn't a model. I am just curious to see what it would look like. Sorry I didn't make that clear. You can go back to important avatar banter.

Being as though I wasn't involved in avatar banter, not sure what you're talking about. But I dunno, we should probably make a thread for instructions on drawing a line on a map?

Sounds easy enough until you have to draw the 3 and 5 day cones of uncertainty. That's two more lines and just adds to the difficulty.

this bears repeating:

History absolutely triumphs over hype, if you have large sample sizes. If you look at Uncle W's thread, the sample size for August TCs in Irene's area is about 10, and some of those data points are from old storms with low confidence in the data. Forecasting anything based on a sample size of 10 is basically pointless. Case in point, Irene is on or a little south of the Florida track and definitely not headed to Florida.

Maximum logic.

I didn't predict she was going to Florida, and there are 3 general tracks ID'd in the NOAA graphic I posted. also, climo for August favors recurves because of the overall dynamics of the atmosphere.

science trumps weenie wishcasting.

climo is gawx level stuff...even if she recurves posting the NHC mean august tracks isn't that relevant

I'm not disagreeing with your last point, just noting that Irene is much closer to the mean Florida track then the mean recurve track. I note those graphics show both mean paths and--to some extent--variation around those means. The variation is just as important as the mean. You are in effect arguing that even though Irene is currently on the mean of the Florida track, you think a better prediction is to think of it as being on the left-hand tail of the distribution around the mean of the recurve track. Fair enough.

Here's the challenge in using small n historical samples with limited data. Suppose you are interested in finding a college for your kid. You have lots of data about post-baccalaureate life course performance of graduating students. That's great. However you only care about your kid - the mean isn't important to you, only where your kid is likely to end up on the distribution. Now imagine that you have lots of information about your kid but very little informantion about school performance, and less about the relationship between your kids attribtues and expected school performance. That's about where we are with Irene. History is fine, if there's lots of it. here thereis not so much.

To bad the folks along the Jersey shore in 1903 are not around to hear your encouraging news.

it may or may not....regardless of what that brightly colored climo map that adds very little to the substance of the discussion shows.

So what's your forecast? I have been lurking and the climo map is more substantive than anything you have provided (basicly just putting down others).
