Internal climate variability at the centennial time scale is investigated using long control integrations from three state-of-the-art global coupled general circulation models. In the absence of external forcing, all three models produce centennial variability in the mean zonal sea surface temperature (SST) and sea level pressure (SLP) gradients in the equatorial Pacific with counterparts in th...

Two common indicators of Atlantic climate variability, viz., the North Atlantic oscillation (NAO) and the crossintertropical convergence zone (ITCZ) sea surface temperature (SST) gradient, are examined for their frequency characteristics and midlatitude-tropical links. SST anomalies north and south of the ITCZ are found to be uncorrelated on all time scales, while the sea level pressure (SLP) f...

Within the Baltic Sea Region INTERREG IIIB project `Sea level change affecting the spatial development in the Baltic Sea region' (SEAREG, 2002-2005) sea levels in past and future climate were investigated based upon 6-hourly regional model results. The main factors affecting the longterm mean sea level in the Baltic Sea are the land-uplift, the eustatic sea level rise, and the water balance of ...

Decadal variations of very small amplitude [;0.38C in sea surface temperature (SST)] in the tropical Pacific Ocean, the genesis region of the interannual El Niño–Southern Oscillation (ENSO) phenomenon, have been shown to have powerful impacts on global climate. Future projections from different climate models do not agree on how this critical feature will change under the influence of anthropog...

The relationship between winter climate extremes across the northeasternUnited States and adjacent parts of Canada and some important modes of climate variability are examined to determine how these circulation patterns are related to extreme events. Linear correlations between 15 extreme climate indices related to winter daily precipitation, maximum and minimum temperature, and three dominant ...

This study investigates the response of large-scale atmospheric circulation over the Asian-Pacific sector and precipitation over eastern China to transient orbital changes during the Holocene summer using an intermediate-complexity climate model. Corresponding to variations in the incoming solar radiation, the eddy sea level pressure (SLP) exhibited an out-of-phase relationship between the Nort...

Abstract. We re-examine the uncertainty of El Niño–Southern Oscillation (ENSO) teleconnection to North Atlantic following investigation Deser et al. (2017) (DES2017). Our analyses are performed on November–December (ND) and January–February (JF) means separately for a geographical area that covers larger extent in midlatitude than DES2017. The motivation splitting cold season this way arises fr...

We use long instrumental temperature series together with available field reconstructions of sea-level pressure (SLP) and three-dimensional climate model simulations to analyze relations between temperature anomalies and atmospheric circulation patterns over much of Europe and the Mediterranean for the late winter/early spring (January–April, JFMA) season. A Canonical Correlation Analysis (CCA)...

[1] Year-to-year variations in summer drawdown of Northern Hemisphere atmospheric carbon dioxide (CO2) are compared with corresponding year-to-year variations in sealevel pressure (SLP), surface air temperature, and the productivity of land vegetation as inferred from the satellite-derived normalized difference vegetation index (NDVI). Annual values of CO2 drawdown for the years 1980–2000 are e...
