It is shown that this parameter varied quasi-periodically with a wavelength of 30-50 years. The correlation of the newly obtained record with the circulation indices of the Southern Hemisphere (SH) shows that the central Antarctic climate is mainly governed by the type of circulation in the SH: under conditions of zonal circulation, negative anomalies of temperature and precipitation rate are observed, whereas the sign of the anomalies is positive during meridional circulation. In the 1970s the sign of the relationship between many climatic parameters changed, which is likely related to the rearrangement of the climatic system of the SH. The data suggest that during the past 350 years such events have taken place at least five times. The stable water isotope content of the central Antarctic snow is governed by the summer temperature rather than the mean annual temperature, which is interpreted as the influence of 'post-depositional' effects. #------------------ # Funding_Agency # Funding_Agency_Name: # Grant: #------------------ # Site_Information # Site_Name: Vostok # Location: Antarctica # Country: # Northernmost_Latitude: -78.2785 # Southernmost_Latitude: -78.2785 # Easternmost_Longitude: 104.8005 # Westernmost_Longitude: 104.8005 # Elevation: 3488 m #------------------ # Data_Collection # Collection_Name: Vostok2014temp # Earliest_Year: 1730 # Most_Recent_Year: 2010 # Time_Unit: AD # Core_Length: # Notes: #------------------ # Chronology: # Chronology: #------------------ # Variables # # Data variables follow that are preceded by "##" in columns one and two. # Data line variables format: Variables list, one per line, shortname-tab-longname-tab-longname components ( 10 components: what, material, error, units, seasonality, archive, detail, method, C or N for Character or Numeric data, additional_information) # ## age_CE age, , , year CE, , , , ,N, ## tempanom temperature anomaly, , , deg.
