Future changes in extratropical storm tracks and baroclinicity under climate change
The weather in Eurasia, Australia, and North and South America is largely controlled by the strength and position of extratropical storm tracks. Future climate change will likely affect these storm tracks and the associated transport of energy, momentum, and water vapour. Many recent studies have analyzed how storm tracks will change under climate change, and how these changes are related to at...
متن کاملUnderstanding the varied response of the extratropical storm tracks to climate change.
Transient eddies in the extratropical storm tracks are a primary mechanism for the transport of momentum, energy, and water in the atmosphere, and as such are a major component of the climate system. Changes in the extratropical storm tracks under global warming would impact these transports, the ocean circulation and carbon cycle, and society through changing weather patterns. I show that the ...
متن کاملDeconstructing the climate change response of the Northern 1 Hemisphere wintertime storm tracks
There are large uncertainties in the circulation response of the atmosphere to climate change. 6 One manifestation of this is the substantial spread in projections for the extratropical storm tracks made 7 by different state-of-the-art climate models. In this study we perform a series of sensitivity experiments, 8 with the atmosphere component of a single climate model, in order to identify the...
متن کاملChanging Northern Hemisphere Storm Tracks in an Ensemble of IPCC Climate Change Simulations
Winter storm-track activity over the Northern Hemisphere and its changes in a greenhouse gas scenario (the Special Report on Emission Scenarios A1B forcing) are computed from an ensemble of 23 single runs from 16 coupled global climate models (CGCMs). All models reproduce the general structures of the observed climatological storm-track pattern under present-day forcing conditions. Ensemble mea...
متن کاملDynamics of Barotropic Storm Tracks
Longitudinal variations in the upper-tropospheric time-mean flow strongly modulate the structure and amplitude of upper-tropospheric eddies. This barotropic modulation is studied using simple models of wave propagation through zonally varying basic states that consist of contours separating regions of uniform barotropic potential vorticity. Such basic states represent in a simple manner the pot...
