Tropical upper-tropospheric troughs (TUTTs), also known as midoceanic troughs, are elongated troughs that appear in summer monthly averaged maps of the upper-tropospheric flow over the oceans. The transient part of these climatological features is composed of TUTT cells and their origin is the subject of this study. TUTT cells often occur to the east of tropical cyclones. A nonlinear shallow wa...

Topography affects the patterns of forest disturbance produced by tropical cyclones. It determines the degree of exposure of a surface and can alter wind characteristics. Whether multispectral remote sensing data can sense the effect of topography on disturbance is a question that deserves attention given the multi-scale spatial coverage of these data and the projected increase in intensity of ...

ANZJPH © 2011 Public Health Association of Australia was the causative organism in seven causes, Aeromonas hydrophilia in six and Methicillin-resistant Staphylococcus aureus (MRSA) in one. Cyclone Yasi was the worst storm to hit Far North Queensland in recorded history. Recent weather patterns suggest an increasing freq...

Previous studies have indicated that recurving western North Pacific tropical cyclones, initially westward moving tropical cyclones that turn toward the east, often reach their maximum intensity close to the time of recurvature. Those results have often been cited in the literature and sometimes inferred to be valid in other tropical cyclone basins. This study revisits this topic in the western...

OBJECTIVES We investigated the short-term impact of Typhoon Haiyan, one of the strongest typhoons ever to make landfall, on the pattern of admissions in two hospitals in Eastern Visayas, the Philippines. METHODS This study took place at Eastern Visayas Regional Medical Center (EVRMC) in Tacloban, and Ormoc District Hospital (ODH) in Ormoc. We determined whether there were differences in the p...

The isotope signatures registered in speleothems during tropical cyclones (TC) provides information about the frequency and intensity of past TCs but the precise relationship between isotopic composition and the meteorology of TCs remain uncertain. Here we present continuous δ18O and δ2H data in rainfall and water vapour, as well as in discrete rainfall samples, during the passage of TC Ita and...

[1] Surface wind and temperature records from the European Centre for MediumRange Weather Forecasts 40 Year Reanalysis (ERA-40) Project are used to estimate low-frequency variations in globally integrated tropical cyclone (TC) intensity from 1958 to 2001. For the first time, the annually integrated power dissipation (PD) is explicitly calculated on a global scale, and results show an upward tre...

10 The global network of subsea fibre-optic cables plays a critical role in the world economy and is 11 considered as strategic infrastructure for many nations. Sediment density flows have caused 12 significant disruption to this network in the recent past. These cable breaks represent the only 13 means to actively monitor such flows over large oceanic regions. Here, we use a global cable break...

Tropical cyclones have massive economic, social, and ecological impacts, and models of their occurrence influence many planning activities from setting insurance premiums to conservation planning. Most impact models allow for geographically varying cyclone rates but assume that individual storm events occur randomly with constant rate in time. This study analyzes the statistical properties of A...

Atlantic tropical cyclone activity has trended upward in recent decades. The increase coincides with favorable changes in local sea surface temperature and other environmental indices, principally associated with vertical shear and the thermodynamic profile. The relative importance of these environmental factors has not been firmly established. A recent study using a high-resolution dynamical d...
