I think ULL is starting
to put some shear on Ivan. Look at the latest floater. Thunderstorm are starting to erode on the Southwest side. also, there is hardly any outflow there. In fact thunderstorms are starting to develop to the west of Ivan, as Ivan and the ULL interact.

A upper level low pressure area...It forms in the upper Atmosphere which is a cold core/Extratropical kind of system. They normally are 700 millibars or above(200 to 700). Cool fact is that most of the time they form on the northwest side of a surface low. They also sprend jets maxs on there southeastern/northern sides. Which can also help the outflow in a tropical cyclone or if affected by the "shear" can also distroy or stop development of tropcial cyclones.
The low pressure of a hurricane has the strongest low pressure closest to the surface. With weaker low pressure as you go up. Intill you get into the upper levels of the tropical cyclone. Then you have a upper level high.
A surface low or cold core low is not stacked like a tropical cyclone. They lean on there side with the upper level low normally on the northwest side of the surface low/Extratropical-depression(Europe).
Outflow jet is what forms on the southeast side/Quad of the jet...They can help a tropical cyclone/or distroy one.

floater is the GOES satellites imagery when they are positioned directly on a storm
go to http://www.nhc.noaa.gov and lcick on the satellitei magery, then the floaters
