Description:

The deployment of a multistatic radar network in the Oklahoma City metropolitan area in Spring 2024 has allowed for unique observations of several severe weather events. This passive multistatic network operates in conjunction with the operational KTLX WSR‐88D, allowing for synchronous multi‐Doppler analyses. This work presents a case study of a tornadic mesovortex in central Oklahoma. Prior to tornadogenesis, a horizontal rotor circulation is tilted into the mesovortex, providing a pathway for an intense low‐level updraft to develop. The release of horizontal shearing instability beneath this updraft is shown to supply near‐surface vertical vorticity, which is then amplified by vertical stretching, which is followed by tornadogenesis. The ability to derive kinematic fields from a single operational radar represents a major expansion of the current observational capabilities of the WSR‐88D network.
