Atmospheric Circulation Response to Short-Term Arctic Warming in an Idealized Model
(Journal article; Peer reviewed, 2020)Recent Arctic sea ice loss in fall has been posited to drive midlatitude circulation changes into winter and even spring. Past work has shown that sea ice loss can indeed trigger a weakening of the stratospheric polar ... -
Direct and Indirect Effects of Surface Fluxes on Moist Baroclinic Development in an Idealized Framework
(Journal article; Peer reviewed, 2020-09)The convoluted role of surface sensible and latent heat fluxes on moist baroclinic development demands a better understanding to disentangle their local and remote effects. Including diabatic effects in the Eady model, the ... -
Dynamics of anomalous stratospheric eddy heat flux events in an idealized model
(Journal article; Peer reviewed, 2020-05-28)Extreme stratospheric eddy and sudden stratospheric warming (SSW) events both involve anomalous stratospheric eddy heat flux. The cause of the anomaly has been hypothesized to be due to tropospheric or stratospheric dynamics. ... -
The Effect of Sea Surface Temperature Fronts on Atmospheric Frontogenesis
(Journal article; Peer reviewed, 2021)It is thought that the sensible heat fluxes associated with sea surface temperature (SST) fronts can affect the genesis and evolution of atmospheric fronts. An analytic model is developed and used to explore this idea. The ... -
How does latent cooling affect baroclinic development in an idealized framework?
(Peer reviewed; Journal article, 2019)Latent cooling by evaporating or melting hydrometeors has recently been shown to contribute to the positive low-level potential vorticity (PV) anomaly below the layer of latent heating in midlatitude cyclones. While the ... -
A New Look at Deformation as a Diagnostic for Large-Scale Flow
(Peer reviewed; Journal article, 2014-11)Deformation plays a key role in atmospheric dynamics because it provides a dynamical measure of the interaction between different scales, such as in frontogenesis. A climatology of deformation constructed from Interim ECMWF ... -
On the Influence of Sea Surface Temperature distributions on the Development of Extratropical Cyclones
(Journal article; Peer reviewed, 2021)The sea surface temperature (SST) distribution can modulate the development of extratropical cyclones through sensible and latent heat fluxes. However, the direct and indirect effects of these surface fluxes, and thus the ...
