High frequency of ‘super-cyclones’ along the Great Barrier Reef over the past 5,000 years

  author={Jonathan Nott and Matthew Hayne},
Understanding long-term variability in the occurrence of tropical cyclones that are of extreme intensity is important for determining their role in ecological disturbances, for predicting present and future community vulnerability and economic loss and for assessing whether changes in the variability of such cyclones are induced by climate change. Our ability to accurately make these assessments has been limited by the short (less than 100 years) instrumented record of cyclone intensity. Here… 

Long-Term Natural Variability of Tropical Cyclones in Australia

Numerous late Holocene records of tropical cyclones have been collected from tropical northern Australia. They are in the form of multiple shore parallel sedimentary ridges deposited over the past

Australian tropical cyclone activity lower than at any time over the past 550–1,500 years

It is shown, on the basis of a new tropical cyclone activity index (CAI), that the present low levels of storm activity on the mid west and northeast coasts of Australia are unprecedented over the past 550 to 1,500 years.

Coastal Hazards from Tropical Cyclones and Extratropical Winter Storms Based on Holocene Storm Chronologies

Aware of past and future climate changes, the question arose whether modern instrumental data adequately reflect the chronology of tropical cyclones and extratropical winter storms for the period of

Punctuated global tropical cyclone activity over the past 5,000 years

There are now a substantial number of millennial scale records of tropical cyclones from a variety of locations globally. Some of these, such as those in the Atlantic and Gulf of Mexico, show

Intense hurricane activity over the past 5,000 years controlled by El Niño and the West African monsoon

Comparison of the sediment record with palaeo-climate records indicates that this variability was probably modulated by atmospheric dynamics associated with variations in the El Niño/Southern Oscillation and the strength of the West African monsoon, and suggests that sea surface temperatures as high as at present are not necessary to support intervals of frequent intense hurricanes.

Intensity of prehistoric tropical cyclones

Prediction of future tropical cyclone climate scenarios requires identification of quasi-periodicities at a variety of temporal scales. Extension of records to identify trends at century and

Tropical cyclones, global climate change and the role of Quaternary studies

The number and types of late Quaternary records of tropical cyclones (TCs) and temperate storms have been increasing globally over the past 10 years. There are now numerous such records for the

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

Multiple stressors on coral reefs: A long ‐term perspective

Coral reefs are subject to a high frequency of recurrent biological and physical disturbances. The temporal and spatial scales of these are often large and difficult to study, so that most of our

The Role of Disturbance in Natural Communities

For many communities, a self-reproducing climax state may only exist as an average condition on a relatively large spatial scale, and even that has yet to be rigorously demonstrated.

The Role of History in Community Dynamics: A Modelling Approach

While recent history was important in determining transition probabilities, it had little effect on community dynamics and structure in this system, and falsify a major assumption of standard first-order models that history is irrelevant.

Tropical Cyclone Bebe Creates a New Land Formation on Funafuti Atoll

A huge rubble rampart 18 kilometers long was formed at Funafuti Atoll during tropical cyclone Bebe on 21 October 1972 and indicates that tropical storms may play a significant role in the formation of atoll islets.

A storm surge inundation model for coastal planning and impact studies

A high resolution storm surge inundat ion model has been developed to model coastal flooding due to storm surges. The storm surge model, which features a nesting capability and inundation algorithm,

Climate model simulations provide the foundation for estimating the impacts of climate change. To make useful inferences regarding most impacts, the most accurate and detailed simulations available

The commonly observed high diversity of trees in tropical rain forests and corals on tropical reefs is a nonequilibrium state which, if not disturbed further, will progress toward a low-diversity
