Submarine pipelines are the lifelines of national economy. Under influence typhoons, high-speed currents and waves continuously erode seabed, leading to suspension or even rupture pipelines. Therefore, it is great importance study sediment transport under action currents. A numerical model scouring deposition combining wave established, which considered tidal current, storm surges, wind waves, ...

Hurricanes and tropical storms are heat engines operating between warm oceans the cold upper troposphere. The purpose of this article is to examine existing theories for hurricanes storms, discuss their validity. It argued that contrary previous claims Carnot engines, these systems operate at efficiencies considerably below maximum thermodynamic efficiency. As such, validity current thermodynam...

The importance of accurate typhoon forecasts to the island of Taiwan and the existing challenges in this area are reviewed by Wu and Kuo (1999). A particular area of emphasis is understanding the physical processes resulting from the interaction between typhoons and the Central Mountain Range, which runs across the center of the island. Wu and Kuo (1999) discuss much of the earlier research in ...

Land-based seismic observations of double frequency (DF) microseisms generated during tropical storms Ernesto and Florence are dominated by signals in the 0.15-0.5 Hz band. In contrast, data from sea floor hydrophones in shallow water (70 m depth, 130 km off the New Jersey coast) show dominant signals in the ocean gravity-wave frequency band, 0.02-0.18 Hz, and low amplitudes from 0.18 to 0.3 Hz...

Introduction On August 28, 2011 Tropical Storm Irene made landfall in Connecticut. On October 29, 2011 Connecticut was impacted by Winter Storm Alfred. Both of these storms included high winds and heavy precipitation which resulted in prolonged power outages, disruption of public drinking water systems, property damage, and widespread debris throughout the state. The HEDSS System was utilized t...

We describe the background, architecture and implementation of a user portal for the SCOOP coastal ocean observing and modeling community. SCOOP is engaged in real time prediction of severe weather events, including tropical storms and hurricanes, and provides operational information including wind, storm surge and resulting inundation, which are important for emergency management. The SCOOP po...

The pioneering use of satellite-based synthetic aperture radar to characterize tropical cyclones in near-real time has provided a crucial new tool with which forecast powerful storms.

Composite analysis is used to examine environmental and climatology and persistence characteristics of tropical cyclones (TCs) undergoing different intensity changes in the western North Pacific (WPAC) and North Atlantic (ATL) ocean basins. Using the cumulative distribution functions of 24-h intensity changes from the 2003–08 best-track data, four intensity change bins are defined: rapidly inte...

Hurricanes and tropical storms served as natural experiments for investigating whether autism is associated with exposure to stressful events during sensitive periods of gestation. Weather service data identified severe storms in Louisiana from 1980 to 1995 and parishes hit by storm centers during this period. Autism prevalences in different cohorts were calculated using anonymous data on birth...

On 25 September 2005, the US President, responding to growing criticism of the response to Hurricane Katrina, said ‘... is there a natural disaster – of a certain size – that would then enable the Defense Department to become the lead agency in coordinating and leading the response effort? That’s going to be a very important consideration for Congress to think about.’ [1]. Five days later his b...
