Moisture flux from the subtropical North Pacific (driven by SST anomalies in the Kuroshio Extension region)

SEASONALITY: "First, during water uptake, plants are expected to sample the spring growing season precipitation, at the end of the wet season [October-March], as the temperature warms up and before the dry summer months (Feakins and Sessions, 2010; Kahmen et al., 2011; Tipple et al., 2013). During this time, the plants may record the isotopic signature of just a few storms each year heightening variability; however, sedimentary samples integrating a decade might average the signal from > 20 storms. " PARAMETER: "Paleoclimatic interpretation of the precipitation isotopic history recorded in the Crystal Cave has been suggested to record changes in moisture source primarily and local amount effect secondarily (McCabe-Glynn et al., 2013). ... Our record provides an extension of the Crystal Cave isotopic record, from a more southerly coastal location, but likely also records interdecadal variability in the same processes. ... We suggest that the plant leaf wax record preferentially captures spring precipitation isotopic anomalies integrated over decades, providing a sensitive record of atmospheric circulation and moisture source changes.
