DELTA

DELTA (Detecting and Evaluating Low-level Tornado Attributes) is a NOAA campaign that takes many of the assets from the PERiLS campaigns to examine three overarching storm modes QLCSs (Quasi-Linear Convective Systems), supercells, and supercell/QLCS mixed mode in the southeastern United States. 

The DELTA operations will take place from 18 January to 31 March 2024 and the region of operations is similar to that of PERiLS but expanded as far west as central Oklahoma and as far north as central Illinois. 

DELTA is a mobile campaign with mobile radars (NOXP, RaXPol, and two SMART-Rs, MAX, and SKYLER), mobile lidars (NSSL and ULM), mobile mesonets (NSSL), mobile soundings (NSSL, ULM, and UAH), UAS, UAH RaDAPS, and the Purdue PIPS systems. Additionally NOAA/PSL will operate several fixed wind and thermodynamic profiler sites.
