I find it curious that the NOGAPS model just barely recognizes that Dean even exists and doesn't even havr Dean on its runs past 90 hours. I dont' have a whole lot of experience with these individual models, having just started to view them during last season (not much to go on there). Can someone explain why this sort of anomaly occurs? It just seems to really cast doubt on that model (at least in this situation) and its ability to forcast tropical cyclones. Or does NOGAPS know something that the others don't? Be as technical as you want to be...I can keep up!
