The Extratropical Transitions of Hurricanes Felix and Iris in 1995

open access: yesMonthly Weather Review, 2000
Abstract The extratropical transitions of Hurricanes Felix and Iris in 1995 are examined and compared. Both systems affected northwest Europe but only Iris developed significantly as an extratropical system. In both cases the hurricane interacts with a preexisting extratropical system over the western Atlantic.

Strange Storms: Rainfall Extremes From the Remnants of Hurricane Ida (2021) in the Northeastern US

open access: yesWater Resources Research, 2023
On 1 September 2021, the remnants of Hurricane Ida transformed into a lethal variant of tropical cyclone in which unprecedented short‐duration rainfall from clusters of supercells produced catastrophic flooding in watersheds of the Northeastern US. Short‐

Added Value of CESM‐Driven WRF for Mean and Extreme Precipitation Over Complex Terrain in Southwest Asia

open access: yesInternational Journal of Climatology, EarlyView.
Southwest Asia remains understudied in high‐resolution regional climate modelling despite its climatic sensitivity and complex orography. We compare WRF (10 km), CESM (~2°), and ERA5 (0.25°) for 1950–2002, with supplementary validation against CHIRPS and PERSIANN‐CDR. WRF corrects the unrealistic summer precipitation overestimation of CESM and improves

Assessment of the Exposure of Australia to Tropical Cyclones Through a Climatological Model for Cyclone Weather Extent

open access: yesInternational Journal of Climatology, EarlyView.
Australia has different levels of exposure to tropical cyclones. Using historical records, this study investigates the spatial variability of tropical cyclone formation across the Southeast Indian–South Pacific basin, quantifies the exposure of different parts of Australia to tropical cyclone weather events, and examines decadal variability in cyclone ...

Comparison of extratropical cyclone characteristics from atmospheric global climate model simulations at different resolutions [PDF]

open access: yes, 2013
Extratropical cyclones play a key role in weather and climate at mid and high latitudes. They are simulated with Atmospheric Global Climate Models (AGCMs) for weather forecasting and future climate projections.

Quantification of the Downstream Impact of Extratropical Transition for Typhoon Jangmi and Other Case Studies [PDF]

open access: yes, 2015
The impact of extratropical transition on the midlatitude flow is quantified based on potential vorticity inversion. The detailed study of Typhoon Jangmi (2008) reveals the diabatically enhanced net transport of low-PV air to the tropopause as the key ...

Electron probe microanalysis of extremely fine‐grained tephras: new protocols and insights for analyses at the 1 μ ${\rm{\mu }}$m scale

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Volcanic ash (tephra) provides an important chronostratigraphic framework for correlating Quaternary records. In ultra‐distal ( > $\gt $1500 km) settings such as ice cores and marine sediments, deposits are typically preserved as cryptotephra composed of glass shards ≤ 20 μ $\le 20\,\mu

Forest or tundra? How different vegetation reconstructions of Last Glacial landscapes in Europe may shape our perception of early human dispersal processes

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Regional variability and long‐term changes of past ecosystems likely had a strong impact on hunter–gatherer population dynamics, including the expansion of anatomically modern humans and the disappearance of Neanderthals. However, our understanding of these ecosystems remains limited, even when looking at large‐scale patterns, such as the ...

Filamentary structure in chemical tracer distributions near the subtropical jet following a wave breaking event [PDF]

open access: yesAtmospheric Chemistry and Physics, 2013
This paper presents a set of observations and analyses of trace gas cross sections in the extratropical upper troposphere/lower stratosphere (UTLS). The spatially highly resolved (≈0.5 km vertically and 12.5 km horizontally) cross sections of ...
