I hope someone can help me out here. I've posted a lot but am obviously quite the newbie, and have not really understood what I have seen in the sat images for Franklin from practically day one, which is a little frustrating. I am trying very hard to read the sat images. So please tell me if this is correct.
I can see something spinning counterclockwise to the west over the FL and that is a low, right? Then to the N is some kind of boundary? It is less distinct now than some hours ago - what is that.
It looks like, where Franklin is, I am seeing two different layers of clouds spinning 'round instead of one, not exactly on top of each other. Why is that. How are folks determining where the center is and the direction, if this is the case. Is it a matter of being very skilled at looking at the sat images? Am I wrong in seeing what appears to be a move to the S for one layer of clouds and a move to the E for another lower layer?
At least I did see one thing - the transverse banding Clark was talking about. I looked it up on the web and then did see it on the sat image. I guess cirrus are the easiest clouds to recognise.
1. The NHC is determining where the center is by seeing where the lowest pressure is.
2. What you are seeing is the different cloud layers, e.g high level and low level clouds. They don't necessarily move in tandem, but it gives you a perspective of how deep the storm actually is.
3. To the north there a trof digging down, that was associated with the rain and severe thunderstorms that we had in the NE yesterday.
4. Cirrus clouds are the easiest to reconginze because they are the highest. Figuring out clouds from visible satellite imagery takes time and practice.
