CycloTRACK (v1.0) – tracking winter extratropical cyclones based on relative vorticity: sensitivity to data filtering and other relevant parameters
winter extratropical cyclones relative vorticity sensitivity to data filtering other relevant parameters
2014/12/19
In this study we present a new cyclone identification and tracking algorithm, cycloTRACK. The algorithm describes an iterative process. At each time step it identifies all potential cyclone centers, d...
Inherently mass-conservative version of the semi-Lagrangian absolute vorticity (SL-AV) atmospheric model dynamical core

The semi-Lagrangian absolute vorticity (SL-AV)
atmospheric model is the global semi-Lagrangian hydrostatic model used for operational medium-range and seasonal
forecasts at the Hydrometeorological C...
High resolution numerical study of the Algiers 2001 flash flood: sensitivity to the upper-level potential vorticity anomaly
Algiers flash flood
2010/1/27
From 9 to 11 November 2001, intense cyclogenesis affected the northern coasts of Africa and more particularly the densely populated city of Algiers. During the morning of 10 November, more than 130 mm...
Potential-vorticity inversion and the wave-turbulence jigsaw: some recent clarifications
Potential-vorticity inversion wave-turbulence jigsaw clarifications
2010/1/28
Two key ideas stand out as crucial to understanding atmosphere-ocean dynamics, and the dynamics of other planets including the gas giants. The first key idea is the invertibility principle for potenti...
