Slide 2 of 23
Notes:
In preparation for this module, forecasters/meteorologists need to first review USAFETAC/TN--92/004, PAG: 2-37 to 2-66
Forecasters working the Southern and Northern Hemispheres should avoid using positive vorticity advection (PVA) and negative vorticity advection (NVA). Instead, forecasters and meteorologists should use cyclonic vorticity advection and anticyclonic vorticity advection.
