Clark, looking at the obs, the old td 10 wave is oriented sw to ne. the one wave behind it (around 62.5 w) is oriented se to nw. Here's the question/ request for clarification. From what I understand, a wave oriented from sw to ne does not typically have the orientation to spin up into a surface low, however a wave oriented se to nw has a better chance of "rolling on itself and closing off a low. Is this correct? Part two, what happens when wave oriented like this collide, do they have a better chance to spin up, considering the conflicting orientations? I know this is a matter of physics, so I thought I'd ask you. It does look like that wave behind the old td 10 wave is catching up. I was wondering if the conflict in orientation and wind dynamics would increase chances of development if they collide with each other.
Thanks for your answer!
