Two Centuries of Drought History in the Center of Chihuahua, Mexico

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