Let’s say your storm’s velocity data crosses into the dreaded “purple haze”. This  loss of velocity data also results in a loss of single-radar Az Shear data. So, what do you do if you’re on the warning desk? Do you scream and panic? No, that wouldn’t be ideal. Rather, take a look at the Merged-shear products. In this example, a strong storm moved into the “purple haze” of KMXX’s radar, thus losing reliable velocity and single-radar AZ Shear data. However, surrounding area radars are still getting a good reading on the storm, and thus the operational forecaster can utilize the Merged Shear products to calm their nerves as to whether the storm is still worthy of maintaining focus on it.
