Our research group is involved in a number of areas currently. Listed below is a sample of ongoing research.


Texas Tech has been heavily involved in the Verification of the Origin of Rotation in Tornadoes Experiment (VORTEX2 - 2009, 2010; VORTEX-SE/USA - 2016-current). During these seasons, a wealth of data were collected by a broad spectrum of radar and in situ data platforms. Texas Tech, specifically, has brought two types of instrument platforms to the field.

Current avenues of research include:

Since 2016, we have been involved in a Congressionally mandated project named VORTEX-SE (now VORTEX-USA), aimed at an improved understanding of conditions leading to tornado development in the southeastern United States. We are excited to begin a new field effort, the Propagation and Evoluation of Rotation in Linear Systems (PERiLS) Experiment, in 2022 and 2023!

TORUS Project

In collaboration with the University of Colorado and the University of Nebraska-Lincoln, we were part of the Targeted Observation by Radars and UAS of Supercells (TORUS) project in 2019. The second field season (COVID-delayed) will be in 2022.
The overarching goal of this project is to use unmanned aircraft systems (UAS), mobile Doppler radars and surface in situ measurements to characterize thermodynamic and kinematic gradients along flanking boundaries of supercells that are believed to be relevant to the genesis and maintenance of tornadoes.

Dryline Structure and Convection Initiation

The West Texas region outlines the climatological maximum in dryline activity. Understanding the critical role of drylines in the initiation of severe thunderstorms, we are focused on a few key areas:
