WRF-ARW simulation of potential temperature at 1000 meters, with horizontal wind vectors. Key features include: enhancement of Sandy's inner warm-core temperature when passing over the axis of the Gulf Stream; cyclonic encirclement of the cold continental polar air. Both processes increased the baroclinicity and wind speed surrounding Sandy's warm inner core and decreased the central pressure preceding landfall. Color indicates potential temperature in degrees C. Discussed in Mel Shapiro's presentation at the AMS 2013 Townhall "A research-community perspective of the life cycle of Hurricane Sandy"
