Northern Hemisphere atmospheric blocking as simulated
Northern Hemisphere atmospheric blocking as simulated by 15 atmospheric general circulation models in the period 1979–1988 Abstract As a part of the Atmospheric Model Inter-comparison Project (AMIP), the behaviour of 15 general circulation models has been analysed in order to diagnose and compare the ability of the different models in simulating Northern Hemisphere midlatitude atmospheric block...
متن کاملSouthern Hemisphere Atmospheric Circulation Response to Global Warming
The response of the Southern Hemisphere (SH), extratropical, atmospheric general circulation to transient, anthropogenic, greenhouse warming is investigated in a coupled climate model. The extratropical circulation response consists of a SH summer half-year poleward shift of the westerly jet and a year-round positive wind anomaly in the stratosphere and the tropical upper troposphere. Along wit...
متن کاملDo Climate Models Underestimate the Sensitivity of Northern Hemisphere
The sensitivity of Northern Hemisphere sea ice cover to global temperature change is examined in a group of climate models and in the satellite-era observations. The models are found to have well-defined, distinguishable sensitivities in climate change experiments. The satellite-era observations show a larger sensitivity— a larger decline per degree of warming—than any of the models. To evaluat...
متن کاملThe Preferred Structure of Variability of the Northern Hemisphere Atmospheric Circulation
A nonlinear generalisation of Principal Component Analysis (PCA) is applied to the 500mb geopotential height field of the Northern Hemisphere extratropical atmosphere. It is found that the low-frequency variability of the mid-troposphere is characterised by three distinct quasistationary states. The states are described and compared to those obtained from applications of cluster analyses and li...
متن کاملA Climatology of Northern Hemisphere Blocking
In this paper a 55-yr (1948–2002) Northern Hemisphere blocking climatology is presented. Traditional blocking indices and methodologies are revised and a new blocking detection method is designed. This algorithm detects blocked flows and provides for a better characterization of blocking events with additional information on blocking parameters such as the location of the blocking center, the i...
