Frontal Analysis at 00z, 09/18, along with Eta 850 mb Wind, Total Deformation, and Temps

frontal analysis

Slide Links:

Speaker Notes:

The main ingredients of frontogenesis, total deformation (shaded), strong temperature gradients (temperatures are the dashed green contours), and convergence (wind barbs are orange) are all maximized along and just north of the surface frontal boundary across eastern PA. These are all Eta 0-hr fields at 850 mb, valid at 00z, 9/18/04.
