South of the tip of Greenland, satellite imagery reveals a dynamic duo of comma-shaped swirls.
It’s pretty to look at, but not particularly ominous. This storm has occluded, and the temperature contrast that drove its initial development is breaking down. In other words, it has entered its weakening phase. The inner swirl is detaching from the broader circulation.
Here’s a wide view of the storm, from NASA’s full-disc view:
Now here are two more detailed images, progressively zoomed in, from NASA’s World View Site:
The storm’s minimum central pressure of 985 millibars, as analyzed by the National Weather Service, is nothing to sneeze at, but pretty common for an ocean storm. Exceptional storms have minimum central pressures in the 960 millibars or lower range.
While a somewhat pedestrian storm, its satellite signature and juxtaposition with Greenland are eye-catching and I figured worth sharing.
