A Mid Level Wind Shear product from the CIMSS Tropical Cyclones site (below) showed that this satellite feature had developed along a tight gradient of wind shear off the California coast. Occasionally such shear gradient vortices can produce turbulence that affects aircraft, as was seen in this example.
