Viewing storm trends using merged AzShear products

Merged products end up showing trend information as new sails cuts come in. In the cases below, notice that the northern storm’s AzShear is weakening over time and the southern storm is increasing.

Above, you can see on the northern storm that the last tile shows weaker leading AzShear. At the same time, note that the leading AzShear signature in the southern storm is increasing.

The northern storm continues to dissipate as the upper tilts catch up to the sails cuts that were weakening earlier. While the southern storm continues to increase in AzShear intensity as the sails cuts would suggest.

At this point the northern storm is gone and the southern storm is quite strong and large.

So not only does AzShear provide a situational awareness of the strength of a couplet, it can also show rotational trends in a storm over time assuming that SAILS is turned on. Plus, the more sails the more information you’ll get in these plots. In the case above it appears SAILS2 was on as you’d get two leading signatures before the data merged back into one storm.
