  author={Amy Benoit Frappier and Dork L. Sahagian and Scott J. Carpenter and Luis A. González and Brian R Frappier},
We present a 23 yr stalagmite record (1977-2000) of oxygen isotope variation, associated with 11 tropical cyclones (TCs), from Actun Tunichil Muknal cave in central Belize. High-resolution microsampling yielded a record of monthly to weekly temporal resolution that contains abrupt decreases (negative excursions) in calcite δ 18 O values that correspond with recent TC rain events nearby. A logistic discriminant model reliably identifi ed TC proxy signals using the measurable parameters δ 18 O…

Verification of tropical cyclone deposits with oxygen isotope analyses of coeval ostracod valves
Reconstruction of prehistoric tropical cyclone (TC) activity often relies on the identification of distinctive overwash deposits (tempestites) in coastal lagoon sediments. Similar sediment deposits,
Deciphering key processes controlling rainfall isotopic variability during extreme tropical cyclones
The isotopic evolution of a tropical cyclone is studied in detail which helps disentangle the key processes governing rainfall isotope variability in the region.
High-Resolution Speleothem-Based Palaeoclimate Records From New Zealand Reveal Robust Teleconnection To North Atlantic During MIS 1-4
Growth rates, δO and δC of five stalagmites from the west coasts of North and South Islands, New Zealand, provide records of millennial-scale climate variability over the last ~75 kyr. Thirty-five
Stable Isotope Anatomy of Tropical Cyclone Ita, North-Eastern Australia, April 2014
High-resolution isotope studies of modern TCs refine the interpretation of stable isotope signatures found in speleothems and other paleo archives and should aim to further investigate the influence of cyclone intensity and longevity on the isotopic composition of associated rainfall.
Hydrological modeling of stalagmite δ18O response to glacial‐interglacial transitions
Stalagmite δ18Ο series currently provide the most robustly dated characterization of glacial terminations. However, uncertainties associated with the stalagmite δ18Ο proxy record arise due to the
Stable Isotope Composition of Cyclone Mekunu Rainfall, Southern Oman
Cyclone Mekunu hit the southern Arabian Peninsula in late May 2018 and brought rainfall amounts that accounted for up to 6 times the mean annual precipitation. Coming from the Arabian Sea, a quite
Stable Isotope Analysis of Precipitation Samples Obtained via Crowdsourcing Reveals the Spatiotemporal Evolution of Superstorm Sandy
The power of rapid-response isotope monitoring to elucidate the structure and dynamics of water cycling within synoptic-scale systems and improve the understanding of storm evolution, hydroclimatological impacts, and paleo-storm proxies is demonstrated.
Precipitation stable isotopic signatures of tropical cyclones in Metropolitan Manila, Philippines show significant negative isotopic excursions
Abstract. Tropical cyclones have devastating impacts on the environment, economies, and societies, and may intensify in the coming decades due to climate change. Stable water isotopes serve as
Masking of interannual climate proxy signals by residual tropical cyclone rainwater: Evidence and challenges for low‐latitude speleothem paleoclimatology
The anomalously low oxygen isotope ratio (δ18O values) of tropical cyclone rainfall can transfer proxy information about past tropical cyclone activity to stalagmite oxygen isotope records.

Tree-ring isotope records of tropical cyclone activity
A 220-year record of oxygen isotope values of α-cellulose in longleaf pine tree rings that preserves anomalously low isotopes in the latewood portion of the ring in years corresponding with known 19th and 20th century landfalling/near-coastal tropical storms and hurricanes is presented.
Increasing destructiveness of tropical cyclones over the past 30 years
An index of the potential destructiveness of hurricanes based on the total dissipation of power, integrated over the lifetime of the cyclone, is defined and shows that this index has increased markedly since the mid-1970s, due to both longer storm lifetimes and greater storm intensities.
Tropical Cyclones and Global Climate Change: A Post-IPCC Assessment
Abstract The very limited instrumental record makes extensive analyses of the natural variability of global tropical cyclone activities difficult in most of the tropical cyclone basins. However, in
