The Multiscale Dynamics of the 29 June 2012 Super Derecho

  • Kacie Nicole Shourd and
  • Michael L. Kaplan

22 October 2021

The 29–30 June 2012 “super” derecho was, up until the 10 August 2020 “Iowa Derecho”, the most prolific derecho of modern times. While many of the synoptic-scale precursors to derecho events are understood, the multi-scale dynamics which likely distin...

Vortex Identification across Different Scales

  • Lisa Schielicke,
  • Christoph Peter Gatzen and
  • Patrick Ludwig

4 September 2019

Vortex identification in atmospheric data remains a challenge. One reason is the general presence of shear throughout the atmosphere that interferes with traditional vortex identification methods based on geopotential height or vorticity. Alternative...
