Hemispheric and large-scale land-surface air temperature variations: An extensive revision and an update to 2010: LAND-SURFACE TEMPERATURE VARIATIONS
[1] This study is an extensive revision of the Climatic Research Unit (CRU) land station temperature database that has been used to produce a grid-box data set of 5° latitude × 5° longitudeExpand

Influence of volcanic eruptions on Northern Hemisphere summer temperature over the past 600 years
A network of temperature-sensitive tree-ring-density chronologies provides circum-hemisphere information on year-by-year changes in summer warmth in different regions of the northern boreal forest.Expand

The Arctic Ocean Response to the North Atlantic Oscillation
The climatically sensitive zone of the Arctic Ocean lies squarely within the domain of the North Atlantic oscillation (NAO), one of the most robust recurrent modes of atmospheric behavior. However,Expand

Low-frequency temperature variations from a northern tree ring density
We describe new reconstructions of northern extratropical summer temperatures for nine subcontinental-scale regions and a composite series representing quasi “Northern Hemisphere” temperature changeExpand

North Atlantic oscillation influence on precipitation, river flow and water resources in the Iberian Peninsula
The Iberian Peninsula precipitation and river flow regimes are characterized by large values of inter-annual variability, with large disparities between wet and dry years, especially in southernExpand

Reduced sensitivity of recent tree-growth to temperature at high northern latitudes
Tree-ring chronologies that represent annual changes in the density of wood formed during the late summer can provide a proxy for local summertime air temperature. Here we undertake an examination ofExpand

Precipitation sensitivity to global warming: Comparison of observations with HadCM2 simulations
Recent century-long experiments performed with global climate models have simulated observed trends in global-mean temperature quite successfully when both greenhouse gas and aerosol forcing has beenExpand

Summer Moisture Variability across Europe
Abstract Maps of monthly self-calibrating Palmer Drought Severity Index (SC-PDSI) have been calculated for the period of 1901–2002 for Europe (35°–70°N, 10°W–60°E) with a spatial resolution of 0.5° ×Expand
