That's a good question. Is the floater a different satellite or is it a cropped higher-res image from a regular sat?

The other ones are fixed sats on certain areas, "Floaters" are capable of moving with a system, and can be re-positioned. Is this a good explanation?

No. A floater is nothing more than a regular geostationary satellite, cropped over an area of interest.

Just some one that blames the US for everything. Thats all. This system in fact looks very good. It will be debbyy once a burst blows up near the center.

The "floaters" are just close-up normalized views of an area of interest.

So Floaters are not able to move with the systems? It's kinda a deceiving name then isn't it? ;)

I learn alot on here... thank you to all the pro mets, I appreciate it :D

I would have to guess that the floater satellite was actually just a portion of a larger image rather than a separate satellite. Moving a satellite is not an easy thing to do. Perhaps it's NOT a geostationary satellite, so it could snap pictures of a certain area every time it passes overhead.

I think they just select an output area of a huge image matrix.

Of course they can move with the systems. There really isn't anything happening with the satellite. It's the website that displays the floater that is zoomed over a set of coordinates.

For instance, on the NRL floaters, they use a GOES (or whatever is applicable) satellite, set it to zoom in to X miles to the latest satellite fix/advisory position. That way, the "floater" follows the storm, but in reality... it's just the same old satellite image that the satellite is producing... just artifically zoomed in.

Acording to Dr Grays trapical update at 4:58pm on the weather channel on TV he said this TD has a well defined center of ciculation and could be a hurricane within 12 hours thats what he said tho He also said it was moving to the NW for now should not be a problem to the caribean islands but where from here there not sure, to soon to call.

It IS part of a geostationary satellite. The only other option would be to use a polar orbiter, which CANNOT be used as a floater is used, since you can only gain a useful image over the invest area twice a day.

Senorpepr already provided a clear answer to the question about floaters.

Floaters are Geosyncronous satellites that are shifted to focus on particular areas of interest.

Well, they "move with the system" in the sense that, as the system moves they periodically change the point at which the "floater" is centered.

The RAMDIS site also offers a storm-centered view which continuously moves with the system. I find that less useful than a fixed reference, however.


The other thing done with the "floaters", as well as some of the other views offered by SSD, is a normalization of the image - that is the perpective is removed so that lines of latitude and longitude are perpendicular.
