GOES-15 6.5 µm water vapor channel images (above; click image to play animation; also available as an MP4 movie file) showed the development of a train of stratospheric intrusion vortices over the East Pacific Ocean during the 07 August – 08 August 2014 period. These vortices formed along a middle to upper tropospheric wind shear axis, and propagated toward the northeast.

The corresponding GOES sounder Total Column Ozone product (below; click image to play animation) revealed ozone values as high as 375 Dobson Units (lighter green color enhancement) within the more well-defined stratospheric intrusion vortices, due to the fact that ozone-rich stratospheric air was descending as the tropopause heights were lowered within the cyclonic vortex circulations.
