Wave‐breaking characteristics of midlatitude blocking (2012, methodology): “Pelly and Hoskins (2003) (PH03 hereafter) followed the idea of Lejenäs and Økland, but they introduced an important novelty with the usage of the potential vorticity (PV) field (Hoskins et al., 1985).”
Baroclinic Instability and Loss of Balance (2005, background): “In McWilliams et al. (1998) we show that there is an exact correspondence of these conditions with the onset of gravitational and centrifugal instabilities (associated with change of sign of vertical density gradient and potential vorticity, respectively) for parallel and axisymmetric flows.”
Transport in the Middle Atmosphere (2007, background): “The extratropical tropopause is alternatively identified by a sharp horizontal gradient in PV along isentropic surfaces (Hoskins et al. 1985).”
Influence of microphysical processes on the potential vorticity development in a warm conveyor belt: a case‐study with the limited‐area model COSMO (2012, neutral): “According to Hoskins et al. (1985), PV can be modified by diabatic processes as follows: DPVR= D Dt PV = 1 ρ η·∇(DHR) ≈ 1 ρ ηz · ∂ ∂z (DHR), (2) where D/Dt denotes the material derivative and η the absolute vorticity vector.”
The Extratropical Tropopause Inversion Layer: Global Observations with GPS Data, and a Radiative Forcing Mechanism (2007, background): “4b, with anticyclonic circulation having very low stability below the tropopause (this is also characteristic of balanced dynamical structure; e.g., Hoskins et al. 1985).”
Influence of Environmental Humidity on Tropical Cyclone Size (2009, methodology): “a. Potential vorticity techniques Following the landmark papers of Hoskins et al. (1985) and Davis and Emanuel (1991), numerous studies have utilized the PV framework for the study of tropical cyclones (e.g., Jones et al. 2003, section 3b).”
The Role of the Stratosphere in Subseasonal to Seasonal Prediction: 2. Predictability Arising From Stratosphere‐Troposphere Coupling (2020, background): “, 2000) lead to temperature anomalies over the polar cap that induce pressure anomalies (Hoskins et al., 1985).”
Blocking and Rossby Wave Breaking on the Dynamical Tropopause in the Southern Hemisphere (2007, background): “Renwick and Revell (1999), for example, produced evidence suggesting that blocking in the southeast Pacific was linked with the propagation of 3 The ERA-40 total column heating is described in Kallberg et al. (2005).”
Storm track response to ocean fronts in a global high-resolution climate model (2014, background): “In addition, according to potential vorticity theory, pre-existing disturbances in the upper level storm track will be amplified when a surface temperature anomaly is present below (Hoskins et al. 1985; Kushnir et al. 2002; Nakamura and Shimpo 2004).”
What Is the Polar Vortex and How Does It Influence Weather (2017, background): “…in the abovementioned tro-pospheric vortex studies, the edge of the tropospheric vortex can (as in the stratosphere) be defined from potential vorticity contours on an isentropic surface or (equivalently) potential temperature on a surface of constant potential vorticity (Hoskins et al. 1985).”
A unified approach to energy conservation and potential vorticity dynamics for arbitrarily-structured C-grids (2010, background): “[14], the broad utility of PV stems both from its ability to inform local processes by acting as a Lagrangian tracer and from its ability to inform large-scale, balance-dominated processes through the principle of invertibility.”
