Deciphering key processes controlling rainfall isotopic variability during extreme tropical cyclones

The Mesoamerican and Caribbean (MAC) region is characterized by tropical cyclones (TCs), strong El Niño-Southern Oscillation events, and climate variability that bring unique hazards to socio-ecological systems. Here we report the first characterization of the isotopic evolution of a TC (Hurricane O...

Here we report the first characterization of the isotopic evolution of a TC (Hurricane Otto, 2016) in the MAC region. We use long-term daily rainfall isotopes from Costa Rica and event-based sampling of Hurricanes Irma and Maria (2017), to underpin the dynamical drivers of TC isotope ratios. During Hurricane Otto, rainfall exhibited a large isotopic range, comparable to the annual isotopic cycle. As Hurricane Otto organized into a Category 3, rapid isotopic depletion coupled with a decrease in d-excess indicates efficient isotopic fractionation within ~200 km SW of the warm core.

La región de Mesoamérica y el Caribe (MAC) se caracteriza por ciclones tropicales (CT), fuertes eventos de El Niño-Oscilación del Sur y variabilidad climática que traen peligros únicos a los sistemas socioecológicos. Aquí reportamos la primera caracterización de la evolución isotópica de un TC (Hurricane Otto, 2016) en la región MAC. Utilizamos isótopos de lluvia diaria a largo plazo de Costa Rica y muestreo basado en eventos de los huracanes Irma y María (2017), para respaldar los impulsores dinámicos de las proporciones de isótopos de CT. Durante el huracán Otto, la lluvia exhibió un amplio rango isotópico, comparable al ciclo isotópico anual. A medida que el huracán Otto se organizó en una categoría 3, el rápido agotamiento isotópico junto con una disminución en el exceso d indica un fraccionamiento isotópico eficiente dentro de ~ 200 km al SO del núcleo cálido. Nuestros resultados arrojan luz sobre los procesos clave que gobiernan las proporciones de isótopos de lluvia en la región MAC durante las trayectorias de CT continentales y marítimas, con aplicaciones para la interpretación del paleohidroclima en los trópicos.
