Arkansas and Oklahoma have a history of severe winter storms. To extend that history back beyond the reach of written records, a distinctive tree ring pattern or signature is needed. Storm-caused breakage, branch loss and bending stress provide that signature. We found a severe storm signature in shortleaf pine (Pinus echinata). We used three published site chronologies, a set of five new site chronologies from a growth-and-yield study conducted by Oklahoma State University and the unpublished Shortleaf Canyon chronology from a master's thesis at the University of Arkansas. Our method is based on two ring width values for the first and second growing seasons after the storm standardized to the ring widths of the seven growing seasons after the storm. Concordance between storm years predicted by tree ring patterns and actual storm years was tested using Cohen's Kappa. Concern about confounding of ice storm signals by droughts led us to test concordance between severe storms and drought in July, August and September; results were inconclusive but stand as a warning that these two phenomena cannot be distinguished with certainty in the tree ring record. Damaging severe storms occurred in about 2.8% of all years. Two out of three storms identified as "severe" produced glaze icing. #-------------------- # Funding_Agency # Funding_Agency_Name: # Grant: #-------------------- # Site_Information # Site_Name: Caddo Gap # Location: Arkansas # Northernmost_Latitude: 34.45 # Southernmost_Latitude: 34.45 # Easternmost_Longitude: -93.5 # Westernmost_Longitude: -93.5 # Elevation_m: 248 #-------------------- # Data_Collection # Collection_Name: AR076 # First_Year: 1913 # Last_Year: 2009 # Time_Unit: CE # Core_Length_m: # Parameter_Keywords: ring width # Notes: #-------------------- # Species # Species_Name: Pinus echinata Mill. # Common_Name: shortleaf pine # Tree_Species_Code: PIEC #-------------------- # 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 1913 1.337 1 1914 1.486 1 1915 1.707 1 1916 1.278 1 1917 1.051 1 1918 0.517 1 1919 0.794 1 1920 0.788 1 1921 0.923 1 1922 0.66 1 1923 0.912 1 1924 0.863 1 1925 0.688 1 1926 0.763 1 1927 1.082 1 1928 0.892 1 1929 1.369 1 1930 0.783 2 1931 0.842 3 1932 0.855 4 1933 1.074 4 1934 0.825 4 1935 1.138 4 1936 0.832 5 1937 0.818 5 1938 0.953 5 1939 0.937 5 1940 1.072 5 1941 1.249 7 1942 1.259 9 1943 0.808 9 1944 1.075 9 1945 1.29 9 1946 0.987 9 1947 0.88 11 1948 0.735 12 1949 0.935 12 1950 1.029 12 1951 0.911 13 1952 0.692 13 1953 0.793 14 1954 0.582 15 1955 1.065 15 1956 0.683 16 1957 1.556 16 1958 1.506 16 1959 1.435 17 1960 1.183 17 1961 1.44 17 1962 1.391 17 1963 1.086 17 1964 1.127 17 1965 0.838 17 1966 0.885 17 1967 0.814 17 1968 0.869 17 1969 0.891 17 1970 1.152 17 1971 0.95 17 1972 0.809 17 1973 1.27 17 1974 1.229 17 1975 1.115 17 1976 1.005 17 1977 0.993 17 1978 0.535 17 1979 0.534 17 1980 0.289 17 1981 0.655 17 1982 0.967 17 1983 0.966 17 1984 1.082 17 1985 0.828 17 1986 0.763 17 1987 0.673 17 1988 0.969 17 1989 1.209 17 1990 1.177 17 1991 1.023 17 1992 0.994 17 1993 0.835 17 1994 1.145 17 1995 0.897 17 1996 1.178 17 1997 1.036 17 1998 1.534 17 1999 1.29 17 2000 1.33 17 2001 0.697 17 2002 0.652 17 2003 1.098 17 2004 1.207 17 2005 0.947 16 2006 1.044 16 2007 1.215 16 2008 1.086 5 2009 1.023 5 2010 9.999 0
