North American monsoon precipitation reconstructed from tree-ring latewood.
Geophysical Research Letters, Vol. 40. DOI: 10.1002/grl.50184
The North American monsoon is a major focus of modern and paleoclimate research, but relatively little is known about interannual- to decadal-scale monsoon moisture variability in the pre-instrumental era. This study draws from a new network of subannual tree-ring latewood width chronologies and presents a 470-year reconstruction of monsoon (June-August) standardized precipitation for southwestern North America. Comparison with an independent reconstruction of cool-season (October-April) standardized precipitation indicates that southwestern decadal droughts of the last five centuries were characterized not only by cool-season precipitation deficits but also by concurrent failure of the summer monsoon. Monsoon drought events identified in the past were more severe and persistent than any of the instrumental era. The relationship between winter and summer precipitation is weak, at best, and not time stable. Years with opposing-sign seasonal precipitation anomalies, as noted by other studies, were anomalously frequent during the mid to late 20th century.
STUDY NOTES: Southwestern North America monsoon (June-August) precipitation reconstruction, based on a multispecies tree
ring latewood width chronology network. Target region for the reconstructions is monsoon region 2 (NAM2),
as defined by the North American Monsoon Experiment Forecast Forum (30-35N, 107.75-113.25W). Monthly
precipitation data are from a 0.5 degree gridded product developed by NOAA. NAM2 grid point data were
averaged to produce time series of monthly precipitation and correlation analysis was used to assess
relationships to the subannual tree-ring chronologies. October-April (cool season) and June-August (monsoon)
were selected as the seasons for reconstruction, and precipitation totals for these seasons were converted to
standardized precipitation indices (SPI).
