OAX: Another Example of 3D-VAR Utilized as Good Heads-Up Display

Posted in Live Blogs on by Greg Stumpf.

The below image illustrates once again that 3D-VAR may be best utilized as a “heads-up” display for the biggest storms on the scope.  It appears the best products for this are the max composite updraft speed (upper left) and max divergence above 8km (lower right).

2350 UTC on 5/23. Upper left (max composite updraft speed), upper right (MRMS MESH), lower right (max storm-top divergence), lower left (simulated reflectivity).
