The explosive volcanic eruption signal in northern hemisphere continental temperature records

  title={The explosive volcanic eruption signal in northern hemisphere continental temperature records},
  author={Raymond S. Bradley},
  journal={Climatic Change},
Several catalogs of explosive volcanic eruptions are reviewed and their limitations assessed. A new, homogeneous set of high quality gridded temperature data for continental regions of the northern hemisphere is then examined in relation to the timing of major explosive eruptions. Several of the largest eruptions are associated with significant drops in summer and fall temperatures, whereas pronounced negative anomalies in winter and spring temperatures are generally unrelated to volcanic… Expand
Surface climate responses to explosive volcanic eruptions seen in long European temperature records and mid-to-high latitude tree-ring density around the Northern Hemisphere
Explosive volcanic eruptions are known to have an impact on surface temperatures in the two to three years after the eruption, but our ability to determine the impact is impeded by the paucity ofExpand
The Volcanic Signal in Surface Temperature Observations.
Abstract Climate records of the past 140 years are examined for the impact of major volcanic eruptions on surface temperature. After the low-frequency variations and El Nino/Southern OscillationExpand
Identifying volcanic signals in Irish temperature observations since AD 1800
Large volcanic eruptions have been shown to affect temperature patterns to varying degrees on continental, hemispheric or global scales. However, few studies have systematically explored theExpand

Using analysis of ice-core, tree-ring, and geologic records in conjunction with climate proxy data indicates that multiple eruptions may force climate on decadal time scales, as appears to have occurred during the Little Ice Age. Expand
Volcanic eruptions have the potential to force global climate, provided they are explosive enough to emit at least 1–5 megaton of sulfur gases into the stratosphere. The sulfuric acid produced duringExpand
The Effect of Tropical Explosive Volcanic Eruptions on Surface Air Temperature
The response of surface air temperatures to four major tropical explosive volcanic eruptions is identified. The common features of the average response (the composite) are then compared with theExpand
Determining the spatial response of the climate system to volcanic forcing is of importance in the development of short-term climate prediction and in the assesment of anthropogenic factors such asExpand
Volcanic Eruptions over the Last 5,000 Years from High Elevation Tree-Ring Widths and Frost Rings
Some tree-ring records, due to their great age, the annual resolution of their dates, and their sensitivity to the climatic effects of large volcanic eruptions, are useful in understanding theExpand
Dynamic winter climate response to large tropical volcanic eruptions since 1600
[1] We have analyzed the mean climate response pattern following large tropical volcanic eruptions back to the beginning of the 17th century using a combination of proxy-based reconstructions andExpand
Use of paleo-records in determining variability within the volcanism climate system
Abstract Volcanic eruptions that inject large quantities of sulfur-rich gases into the stratosphere have the capability of cooling global climate by 0.2–0.3°C for several years after the eruption.Expand


Climatic impact of explosive volcanic eruptions
Major explosive volcanic eruptions inject ash and gas into the upper atmosphere, producing aerosol layers which can affect the global energy balance and climate1. Empirical studies have shown thatExpand
The possible effects of large 19th and 20th century volcanic eruptions on zonal and hemispheric surface temperatures
Abstract The contribution of volcanic material to the stratosphere from major eruptions within the last two centuries has been estimated using volcanological criteria, including eruption type,Expand
Recent glacier variations and volcanic eruptions
The injection of volcanic dust and gases into the atmosphere during major eruptions has been advanced to explain short-term variations of climate1–4. A calculated global cooling of ∼1K duringExpand
Volcanic eruptions and long‐term temperature records: An empirical search for cause and effect
The ‘superposed epoch’ analysis method of compositing temperatures is employed to aid in the search for evidence of a drop in surface temperature due to large volcanic dust veils. The temperatureExpand
Global spread of volcanic dust from the Bali eruption of 1963
The global spread of volcanic dust from the Mt. Agung eruption of 17 March 1963 is assessed on the basis of the decrement of direct solar radiation. The initial injection at 8°S lodged an equatorialExpand
The volcanic explosivity index (VEI) an estimate of explosive magnitude for historical volcanism
Knowledge of the frequencies of highly explosive, moderately explosive, and nonexplosive eruptions would be useful in a variety of volcano studies. Historical records are generally incomplete,Expand
Volcanic dust influence on glacier mass balance at high latitudes
EXPLOSIVE eruptions, which inject large quantities of volcanic dust into the earth's upper atmosphere, are believed to be important factors in climatic change. Theoretical considerations suggest thatExpand
Sulphur-rich volcanic eruptions and stratospheric aerosols
During the past decade it has become clear that the long-lived stratospheric clouds produced by volcanic eruptions are composed largely of sulphuric acid aerosols1,2. The amount of sulphur-richExpand
Volcanic deposits in Antarctic snow and ice
Major volcanic eruptions are able to spread large amounts of sulfuric acid all over the world. Acid layers of volcanic origin were detected for the first time a few years ago by Hammer in GreenlandExpand
A decade of stratospheric sulfate measurements compared with observations of volcanic eruptions
Sulfate aerosol concentrations in the stratosphere have been measured for 11 years (1971--1981) using portions of filters collected by the Department of Energy's High Altitude Sampling Program. DataExpand
