Drought over Mexico is modulated by ocean-atmospheric variability in the Atlantic and Pacific, raising the possibility for long-range seasonal climate forecasting, which could help mediate the economic and social impacts of future dry spells. The instrumental record of Mexican climate is very limited before 1920, but tree-ring chronologies developed from old-growth forests in Mexico can provide an excellent proxy representation of the spatial pattern and intensity of past moisture regimes useful for the analysis of climate dynamics and climate impacts. The Mexican Drought Atlas (MXDA) has been developed from an extensive network of 252 climate sensitive tree-ring chronologies in and near Mexico. The MXDA reconstructions extend from 1400 CE-2012 and were calibrated with the instrumental summer (JJA) self-calibrating Palmer Drought Severity Index (scPDSI) on a 0.5 latitude/longitude grid extending over land areas from 14 to 34N and 75-120W using Ensemble Point-by-Point Regression (EPPR) for the 1944-1984 period. The grid point reconstructions were validated for the period 1920-1943 against instrumental gridded scPDSI values based on the fewer weather station observations available during that interval. The MXDA provides a new spatial perspective on the historical impacts of moisture extremes over Mexico during the past 600-years, including the Aztec Drought of One Rabbit in 1454, the drought of El Ano de Hambre in 1785-1786, and the drought that preceded the Mexican Revolution of 1909-1910. # The El Nino/Southern Oscillation (ENSO) is the most important ocean-atmospheric forcing of moisture variability detected with the MXDA. In fact, the reconstructions suggest that the strongest central equatorial Pacific sea surface temperature (SST) teleconnection to the soil moisture balance over North America may reside in northern Mexico. This ENSO signal has stronger and more time-stable correlations than computed for either the Atlantic Multidecadal Oscillation or Pacific Decadal Oscillation. The extended Multivariate ENSO Index is most highly correlated with reconstructed scPDSI over northern Mexico, where warm events favor moist conditions during the winter, spring, and early summer. This ENSO teleconnection to northern Mexico has been strong over the past 150 years, but it has been comparatively weak and non-stationary in the MXDA over central and southern Mexico where eastern tropical Pacific and Caribbean/tropical Atlantic SSTs seem to be more important. The ENSO teleconnection to northern Mexico is weaker in the available instrumental PDSI, but analyses based on the millennium climate simulations with the Community Earth System Model suggest that the moisture balance during the winter, spring, and early summer over northern Mexico may indeed be particularly sensitive to ENSO forcing. Nationwide drought is predicted to become more common with anthropogenic climate change, but the MXDA reconstructions indicate that intense "All Mexico" droughts have been rare over the past 600 years and their frequency does not appear to have increased substantially in recent decades. #-------------------- # Funding_Agency # Funding_Agency_Name: # Grant: #-------------------- # Site_Information # Site_Name: Potosi Culminicola # Location: Mexico # Northernmost_Latitude: 24.87 # Southernmost_Latitude: 24.87 # Easternmost_Longitude: -100.231 # Westernmost_Longitude: -100.231 # Elevation_m: 3560 #-------------------- # Data_Collection # Collection_Name: MEXI096 # First_Year: 1796 # Last_Year: 2010 # Time_Unit: CE # Core_Length_m: # Parameter_Keywords: ring width # Notes: #-------------------- # Species # Species_Name: Pinus culminicola Andresen et Beaman # Common_Name: Potosi Pinyon # Tree_Species_Code: PICU #-------------------- # Variables # # PaST_Thesaurus_Download_Resource: https://www.ncei.noaa.gov/access/paleo-search/skos/past-thesaurus.rdf # PaST_Thesaurus_Download_Description: Paleoenvironmental Standard Terms (PaST) Thesaurus terms, definitions, and relationships in SKOS format. # # Data variables follow that are preceded by '##' in columns one and two. # Variables format: shortname-tab-var components: what, material, error, units, seasonality, data type, detail, method, C or N for Character or Numeric data) # ## age_CE age,,,year Common Era,,tree ring,,,N, ## trsgi tree ring standardized growth index,,,,,tree ring,composited,standard chronology method,N, ## numsamp number of samples,,,count,,tree ring,,,N, #--------------------- # Data: # Missing_Values: NA age_CE trsgi numsamp 1796 0.874 1 1797 0.846 2 1798 0.888 2 1799 0.825 2 1800 0.972 2 1801 0.749 2 1802 0.696 2 1803 0.72 2 1804 0.885 2 1805 0.943 2 1806 0.895 2 1807 0.952 2 1808 0.836 2 1809 0.96 2 1810 0.951 3 1811 1.055 3 1812 1.047 3 1813 0.954 3 1814 0.982 3 1815 0.955 3 1816 1.164 3 1817 1.06 3 1818 1.123 3 1819 0.783 3 1820 1.232 3 1821 1.133 3 1822 1.281 3 1823 1.12 3 1824 1.214 3 1825 1.277 3 1826 0.985 3 1827 1.148 3 1828 1.159 3 1829 1.304 3 1830 0.907 3 1831 1.105 3 1832 1.235 3 1833 1.16 3 1834 1.138 3 1835 1.298 3 1836 1.223 3 1837 1.058 3 1838 0.794 3 1839 1.103 3 1840 1.094 3 1841 1.067 3 1842 1.07 3 1843 0.932 3 1844 0.986 3 1845 1.079 3 1846 0.862 3 1847 0.915 3 1848 1.063 3 1849 1.087 3 1850 1.01 7 1851 1.201 7 1852 1.228 7 1853 1.092 7 1854 1.2 7 1855 1.253 7 1856 0.907 7 1857 0.859 7 1858 0.917 7 1859 0.907 7 1860 0.996 7 1861 1.067 7 1862 0.906 7 1863 0.75 7 1864 0.942 7 1865 0.98 7 1866 1.022 7 1867 1.104 7 1868 0.766 7 1869 1.083 7 1870 0.695 7 1871 0.838 7 1872 1.107 7 1873 1.035 7 1874 1.065 7 1875 0.795 7 1876 1.084 7 1877 0.906 7 1878 0.954 7 1879 0.947 7 1880 0.75 7 1881 0.777 7 1882 1.031 7 1883 0.847 7 1884 0.91 7 1885 0.912 7 1886 0.946 8 1887 0.933 8 1888 0.835 8 1889 1.17 8 1890 0.981 8 1891 0.976 8 1892 0.893 8 1893 0.992 8 1894 0.873 8 1895 1.035 8 1896 1.085 10 1897 1.113 13 1898 1.212 14 1899 1.072 14 1900 0.979 21 1901 1 22 1902 0.917 23 1903 1.083 23 1904 1.037 23 1905 1.141 23 1906 1.031 24 1907 1.014 24 1908 0.895 24 1909 0.785 24 1910 1.091 26 1911 1.077 26 1912 0.973 26 1913 0.847 26 1914 0.882 27 1915 0.825 27 1916 0.454 27 1917 0.503 27 1918 0.911 27 1919 0.967 27 1920 0.826 27 1921 0.857 27 1922 1.026 27 1923 1.05 27 1924 0.844 27 1925 0.848 29 1926 0.644 29 1927 0.85 29 1928 0.967 30 1929 0.756 30 1930 1.097 35 1931 1.066 35 1932 1.039 35 1933 0.941 35 1934 1.045 35 1935 0.927 35 1936 1.09 35 1937 1.208 36 1938 0.91 36 1939 1.281 36 1940 1.217 36 1941 1.1 37 1942 1.323 37 1943 1.308 37 1944 1.244 37 1945 0.986 37 1946 1.016 37 1947 1.043 36 1948 0.897 38 1949 1.083 38 1950 1.116 39 1951 1.01 39 1952 1.221 39 1953 0.839 39 1954 1.329 39 1955 0.957 39 1956 1.108 39 1957 1.108 39 1958 1.232 39 1959 0.926 39 1960 0.74 39 1961 0.868 38 1962 0.967 38 1963 1.156 38 1964 0.863 38 1965 1.019 38 1966 1.061 38 1967 1.043 38 1968 1.15 38 1969 1.154 38 1970 0.969 38 1971 0.824 35 1972 0.974 35 1973 0.993 35 1974 0.986 35 1975 0.816 35 1976 1.057 35 1977 0.507 35 1978 1.034 35 1979 0.999 35 1980 0.89 35 1981 0.92 34 1982 1.02 34 1983 1.126 34 1984 1.107 34 1985 1.168 34 1986 1.111 34 1987 1.111 34 1988 1.29 34 1989 1.001 34 1990 1.442 34 1991 1.091 30 1992 0.928 30 1993 1.122 30 1994 1.156 30 1995 0.981 30 1996 0.96 30 1997 1.159 26 1998 0.517 17 1999 0.606 17 2000 0.78 17 2001 1.119 16 2002 1.097 16 2003 1.096 16 2004 1.243 16 2005 1.378 16 2006 1.231 16 2007 1.143 16 2008 1.051 16 2009 0.984 16 2010 1.282 12
