Interesting Pressure Traces

1 minute pressure trace for Brooklyn
Some of you may be curious about the odd jump and then dip on many of the 1 minute pressure traces recently. The featured plot shows a 2 hour period from yesterday afternoon at the Brooklyn SNET site. These plots are showing the meso-high and then wake low structures that often pass during severe convection. Here are some other examples from Colo, Montezuma, Charles City (10mb!), and Newton. If you look at those plots you can see the two distinct pressure patterns. A quick pressure jump (meso high), a return to the pressure before the jump (wave node), and then a rapid drop (wake low). Great stuff!
