I have studied Hurricane Charley....
And a fact I think is true. That cold front that came and pushed Charley to the Northeast... I think that helped the northern outflow. Any comments on that?

I've been reading some papers by Deborah Hanley from FSU and this is onle one positive effect from trough interaction.
A second mechanism that affects systems is when the trough (as defined by the eddy flux convergence being above a certain value) is within 400km. This is known as superposition. What happens here is we have potential vorticity advection over the center, allowing the system to intenify. Typically, the intensification occurs when the region of PV is small as larger areas of PV also tend to have strong vertical wind shear.
