Pop-up skew-T for AWIPS

The Pop-up skew-T feature in AWIPS works for NUCAPS. This feature allows forecasters to quickly view soundings from NUCAPS before interrogating them further in NSHARP.



Mobile, AL had a special 18z radiosande launch today (shown below). The profile reveals a moist layer below 700 mb, with a dry layer centered around 400 mb. SBCAPE in the sounding is about 2100 j/kg, while TPW is 1.5 inches.



A modified NUCAPS sounding was sampled over the same location. The sounding depicts a similar moist low-layer, with a dry layer around 400 mb. CAPE is about 2200 j/kg, and TPW is 1.36 in, both similar to that from the observed radiosande.
