Annular Modes and Stratosphere-Troposphere Coupling in Chemistry-Climate Models. Stratosphere-troposphere Processes and their Role in Climate (SPARC) 2014 General Assembly, Queenstown, New Zealand, 12-17 January 2014, 2014 (Ref: 15175)
Authors:

Category 3: Poster

This study aims to assess the ability of climate models to reproduce observed stratosphere-troposphere coupling. Coupling between the stratosphere and troposphere is examined via the Southern and Northern Annular Modes (SAM and NAM). These modes…

Patterns of Southern Hemisphere Climate Change and their Relationships. Stratosphere-troposphere Processes and their Role in Climate (SPARC) 2014 General Assembly, Queenstown, New Zealand, 12-17 January 2014, 2014 (Ref: 15173)
Authors:
McDonald A.J.Dennison F.Morgenstern O.Klekociuk A.R.
Category 3: Poster

Trends in surface atmospheric variables, namely temperature, wind speed and direction, cloud cover, and precipitation, display subtle patterns that are likely linked to climate change and the major modes of climate variability. In particular…

Recent Antarctic Climate Change and Its Relation to Stratospheric Ozone Depletion and Increases on Long-lived Greenhouse Gases. Stratosphere-troposphere Processes and their Role in Climate (SPARC) 2014 General Assembly, Queenstown, New Zealand, 12-17 January 2014, 2014 (Ref: 15172)

The continent of Antarctica has experienced some of the largest rates of both surface warming and cooling found anywhere on the planet. Unlike in the Arctic, where sea ice has been declining…
