Resumen:
Droughts are a climatic phenomenon with local, regional, and large-scale
repercussions. Historical knowledge of droughts generated by modeled
data allows the development of more accurate climate reconstructions to
propose better approaches for the management of hydric resources. The
objective of this research was to evaluate the association of
precipitation and temperature with data from the NLDAS-002 to develop a
reconstruction of droughts in the center of Chihuahua, Mexico using the
SPEI from tree rings. We also identified the influence of
ocean-atmospheric phenomena on the reconstructed drought index. The best
association among chronologies was obtained with the earlywood band and
accumulated seasonal precipitation from November of the previous year to
June of the current year (r = 0.82, p < 0.05) and for temperature from
January to July (r = -0.81, p < 0.05). The reconstructed drought index
extended from 1775 to 2017 (243 years), where seven extreme drought
events were identified. We found significant correlations between the
reconstructed Standardized Precipitation Evapotranspiration Index and
the Pacific Decadal Oscillation (r = 0.46, p < 0.05), Atlantic
Multidecadal Oscillation (r = -0.34, p < 0.05), Multivariate El Nino
Southern Oscillation Index (r = 0.29, p < 0.05), and Southern
Oscillation Index (r = -0.22, p < 0.05). The historical reconstruction
of hydroclimatology in the center of Chihuahua is important for planning
a long-term assessment and for the management of water resources shared
by Mexico and the United States.
