Drought duration and frequency in the U.S. Corn Belt during
the last millennium (AD 992-2004).
Agricultural and Forest Meteorology, Vol. 151, Issue 2,
15 February 2011, pp. 154-162. doi:10.1016/j.agrformet.2010.09.010
Drought is among the most costly natural hazards affecting the United
States, averaging $6 to $8 billion annually in damages, primarily in
crop losses. Mitigating the impacts of drought through planning and
preparedness has the potential to save billions of dollars. We used
a new long tree-ring chronology developed from the central U.S. to
reconstruct annual drought and characterize past drought duration,
frequency, and cycles in the U.S. Corn Belt region during the last
millennium. This is the first paleoclimate reconstruction achieved
with subfossil oak wood in the U.S. and increases the current
dendroclimatic record in the central U.S. agricultural region by
over 500 years. A tree ring-width drought response function was
calibrated and verified against monthly instrumental Palmer
Hydrologic Drought Index (PHDI) during the summer season (JJA).
Separate reconstructions tailored to emphasize high-frequency
and low-frequency variations indicate that drought conditions
over the period of instrumental records (since 1895) do not exhibit
the full range of variability, severity, or duration of droughts
during the last millennium. For example, three years in the last
millennium were drier than 1934, a classic Dust-Bowl year and the
driest year of the instrumental period. Thirteen decadal to
multidecadal droughts (i.e., =>10 years) occurred during the last
millennium - the longest lasting sixty-one years and centered on
the late twelfth century. Reconstructions exhibited quasi-periodicity
at bidecadal and century-scale periods. Significant rhythms in drought
were identified near 20-yr and 128-yr periods. The tree-ring drought
reconstruction shows promise in providing new information about
long-term climate variability in the agricultural regions that
could potentially span multimillennia. We postulate that tree-ring
chronologies (i.e., tree growth), thus far under-utilized in
agricultural applications, have the potential to match contributions
of instrumental climate data.
STUDY NOTES: Tree ring reconstruction of summer (June-July-August, JJA) Palmer
Hydrologic Drought Index (PHDI) for the central United States
(Missouri Climate Division 1, Iowa Climate Divisions 7 and 8)
for the past 1093 years. Tree-ring data were derived from a master
oak ring-width chronology spanning the period AD 912 to 2004.
The chronology was developed from live tree cores and sections
of subfossil trees collected from the region of northern Missouri
and southern Iowa, USA, ~41°N, 92°W.
