Stable isotope signatures of seasonal precipitation on the Pacific coast of central Panama

ISOTOPES IN ENVIRONMENTAL AND HEALTH STUDIES, 52(1-2), 128–140.

By: Z. Kern*, R. Harmon n & I. Forizs*

author keywords: Panama; evaporation; tropical hydrometeorology; hydrogen-2; oxygen-18; isotope hydrology; precipitation; ocean; meteoric water line; isotope fractionation
MeSH headings : Deuterium / analysis; Environmental Monitoring; Hydrogen / analysis; Oxygen / analysis; Oxygen Isotopes / analysis; Pacific Ocean; Panama; Rain / chemistry; Seasons
TL;DR: The negative response of May–June rainfall isotopic composition to Caribbean SSTs is explained by a SST-mediated change in stratiform rain fraction from organized convective systems proximal to the Inter Tropical Convergence Zone (ITCZ); the positive correlation for the rest of the wet season is interpreted as simple evaporative temperature effect on isotopic fractionation.
