  text: "Interannual variability of precipitation can directly or indirectly affect
    many hydrological, ecological, and biogeochemical processes that, in turn, influence
    climate. Despite the significant importance of the phenomenon, few studies have
    attempted to elucidate spatial patterns of this variability at the global scale.
    This study uses land gauge precipitation records of the Global Historical Climatology
    Network, version 2, as well as reanalysis data to provide an assessment of the
    spatial organization of characteristics of precipitation interannual variability.
    The coefficient of variation, skewness, and short- and long-range dependence of
    the precipitation variability are analyzed. Among the major inferences is that
    the coefficient of variation of annual precipitation shows a significant correlation
    with intra-annual seasonality. Specifically, subyearly precipitation anomalies
    occurring in locations with pronounced seasonality affect the total yearly amount,
    imposing a higher variability in the annual precipitation fluctuations. Furthermore,
    the study illustrates that a positive skewness of the distribution of annual precipitation
    is a robust property worldwide and its magnitude is related to the coefficient
    of variation. Additionally, annual precipitation exhibits very weak small-lag
    autocorrelation. Conversely, the intensity of long-memory–long-range dependence
    is significantly larger than zero, hinting that organized long-term variations
    are an important feature of the interannual variability of precipitation.\r\n\r\n"
