Abstract Intra-seasonal variability in the Northern Hemisphere winter is investigated in ensembles of experiments using the Hadley Centre coupled ocean-atmosphere model. Synoptic techniques which identify low centres and blocking anticyclones have been used in preference to time-filtered variances of geopotential height as these may not uniquely identify true synoptic systems. Changes in mid-latitude variability are qualitatively similar in experiments that include changes in greenhouse gases… 
Understanding the impact of climate change on Northern Hemisphere extra-tropical cyclones
Extra-tropical cyclones strongly influence weather and climate in mid-latitudes and any future changes may have large impacts on the local scale. In this study Northern Hemisphere storms are analysed
Effect of tropospheric temperature change on the zonal mean circulation and SH winter extratropical cyclones
This study aims to understand the mechanisms which cause an overall reduction of SH extratropical cyclone activity with a slight increase in the high latitudes in a warmer climate simulated in
Changing cyclones and surface wind speeds over the North Atlantic and Europe in a transient GHG experiment
A 240 yr run of the ECHAM4/OPYC3 coupled ocean-atmosphere model with transient greenhouse gas (GHG) forcing according to the IPCC IS92a scenario is examined with respect to sim- ulated changes in
Synoptic conditions of extreme windstorms over Switzerland in a changing climate
This paper reports on a method using composites for studying synoptic conditions of a series of windstorm events selected on the basis of maximum wind speeds in Switzerland. The composite
Evaluation of the North Atlantic Oscillation as simulated by a coupled climate model
Abstract The realism of the Hadley Centre’s coupled climate model (HadCM2) is evaluated in terms of its simulation of the winter North Atlantic Oscillation (NAO), a major natural mode of the Northern
Possible Change of Extratropical Cyclone Activity due to Enhanced Greenhouse Gases and Sulfate Aerosols—Study with a High-Resolution AGCM
Abstract To investigate the possible impacts of enhanced greenhouse gases and sulfate aerosols on extratropical cyclone activity, two 20-yr time-slice experiments—the control run and the global
Changes in winter cyclone frequencies and strengths in transient enhanced greenhouse warming simulations using two coupled climate models
Abstract Changes in winter cyclone frequencies and strengths resulting from global warming are examined in an ensemble of 250‐year transient enhanced greenhouse warming simulations using two versions
Changes in Winter North Atlantic Extratropical Cyclones in High-Resolution Regional Pseudo–Global Warming Simulations
AbstractThe present study investigates changes in the location, frequency, intensity, and dynamical processes of North Atlantic extratropical cyclones with warming consistent with the IPCC Fifth
Modelling the variability of midlatitude storm activity on decadal to century time scales
The output of several multi-century simulations with a coupled ocean–atmosphere general circulation model is examined with respect to the variability of global storm activity in winter on time scales
Using anticyclonicity to determine the position of the Southern Hemisphere westerlies: Implications for the LGM
The possible meridional displacement of southern hemisphere westerlies under a different climate regime is examined by studying the characteristics of surface anticyclones. An atmospheric general


The Dependence of Climate Sensitivity on the Horizontal Resolution of a GCM
Abstract The impact of changing the horizontal resolution of a version of the Hadley Centre GCM is investigated in present-day and 2 × CO2 climate simulations. The use of higher resolution generally
Transient Response of the Hadley Centre Coupled Ocean-Atmosphere Model to Increasing Carbon Dioxide. Part II: Spatial and Temporal Structure of Response
Abstract A high-resolution (2.75° lat × ° 3.75° long) coupled ocean-atmosphere model has been used to simulate the transient response of climate to a gradual increase in atmospheric carbon dioxide
GCM Response of Northern Winter Stationary Waves and Storm Tracks to Increasing Amounts of Carbon Dioxide
Abstract The response of the Geophysical Fluid Dynamics Laboratory (GFDL) coupled ocean-atmosphere R15, 9-level GCM to gradually increasing C02 amounts is analyzed with emphasis on the changes in the
Climate response to increasing levels of greenhouse gases and sulphate aerosols
CLIMATE models suggest that increases in greenhouse-gas concentrations in the atmosphere should have produced a larger global mean warming than has been observed in recent decades, unless the climate

On the Existence of Storm-Tracks.
Abstract Given that middle latitude weather systems transport heat in a manner such as to weaken the baroclinicity that is thought to be crucial to their growth, it is perhaps surprising that
