Nielsen-Gammon, John; Gold, David (2016-10-28)Quantitative diagnosis of low-Rossby-number flows using potential vorticity (PV) includes using elements of PV advection to deduce instantaneous tendencies of the balanced atmospheric state, most commonly the geopotential ...

Gold, David; Nielsen-Gammon, John (American Meteorological Society, 2008-05-01)Observational and modeling studies have shown that shear and instability are powerful predictors of the likelihood of severe weather and tornadoes. To the extent that upper-tropospheric forecast errors can be described as ...

Nielsen-Gammon, John; Gold, David (American Meteorological Society, 2008-05-01)Idealized numerical experiments are conducted to understand the effect of upper-tropospheric potential vorticity (PV) anomalies on an environment conducive to severe weather. Anomalies are specified as a single isolated ...

Gold, David; Nielsen-Gammon, John (American Meteorological Society, 2008-05-01)Nonlinear balance potential vorticity (PV) inversion is used to diagnose the sensitivity of the severe convective parameter space to the amplitude of a subsynoptic-scale PV anomaly on 13 March 1990, a day on which a ...

Gold, David; Nielsen-Gammon, John (American Meteorological Society, 2008-05-01)A potential vorticity (PV) diagnostic framework is used to explore the sensitivity of the 3 May 1999 Oklahoma City tornado outbreak to the strength of a particular PV anomaly proximate to the geographical region experiencing ...
