A millennial long March-July precipitation reconstruction 
for southern-central England. 
Climate Dynamics, Vol. 40, Issue 3-4, pp. 997-1017, February 2013.

  <Summary>
    <Abstract>We present a millennial long dendroclimatic reconstruction 
of spring/summer precipitation for southern-central England. 
Previous research identified a significant moisture stress 
signal in ring-width data measured from oak trees growing 
in southern England. In this study, we build upon this earlier 
work, specifically targeting south-central England, to derive 
a well replicated oak ring-width composite chronology using 
both living and historical material.  The data-set includes 
352 living trees (AD 1629-2009) and 1540 individual historical 
series (AD 663-1925). The period expressed by at least 50 trees 
in any year is AD 980-2009.  Calibration experiments identify 
the optimal seasonal predictand target as March-July precipitation 
(1901-2007: r2 = 0.33). However, comparison with the long Kew 
Gardens precipitation record indicates a weakening in tree-growth/
climate response from ~1800 to 1920 which we speculate may be 
related to smoke and sulphur dioxide (SO2) emissions at that 
time which may have also contributed to a decrease in tree 
productivity. The time-series derived using the regional curve 
standardisation method to capture lower frequency information 
shows a mediaeval period with alternating multi-decade-long dry 
and wet periods, with AD 1153-1172 being the wettest reconstructed 
20-year period in the whole record. Drier conditions are prevalent 
from ~1300 to the early sixteenth century followed by a period of 
increasing precipitation levels. The most recent four centuries 
of the record appear similar to the mediaeval period with multiple 
decade-long dry and wet periods. The late twentieth century is 
the second reconstructed wettest period. These centennial 
hydroclimatic trends are in broad agreement with independent 
regional scale hydroclimatic reconstructions from tree-ring 
(East Anglia), historical, speleothem and peat water level 
proxy archives in the United Kingdom and appear coupled 
with reconstructed sea surface temperature changes in the 
North Atlantic which in turn influence the Atlantic meridional 
overturning circulation and westerly airflow across the UK.
