Comments on the nature of persistence in dendrochronologic records with implications for hydrology and climatology [abstract]

EXTRACT (SEE PDF FOR FULL ABSTRACT): Jurate Landwehr discussed the use of surrogate hydrologic records, specifically dendrochronologic records, to study the nature of persistence which is characteristic of hydrologic phenomenon. These proxy records are generally considered to correspond to such hydrologic measures as mean annual discharge but are much longer in length than directly measured hydrologic records. Consequently, they allow one to explore questions pertaining to the structure of candidate stochastic processes with greater validity than permitted by the latter.
