Storm surges and the resulting extreme high sea levels are among the most dangerous natural disasters and are responsible for widespread social, economic and environmental consequences. Using a set of 220 tide gauges, this paper investigates the temporal variations in storm surges around the world and the spatial coherence of its variability. We compare results derived from two parameters used ...

A hindcast of typical extratropical storm surge occurring in the Bohai Sea in Oct. 2003 is performed using a three-dimensional storm surge model system based on Finite-Volume Coastal Ocean Model (FVCOM). The surface winds are obtained from the WRF data set. Some preliminary sensitivity studies of the influential factors affecting the storm surge simulation in the Bohai Sea are studied with the ...

In the present study, the role of the medial preoptic area (MPO) in the neural control of the nocturnal prolactin (PRL) surge was investigated in ovariectomized rats. Cervical stimulation (CS) or bilateral MPO lesions caused a marked nocturnal PRL surge at 0400 h on the fourth day after CS or the lesions in ovariectomized rats in which blood samples were obtained by decapitation. However, opera...

BACKGROUND Occlusion break surge during phacoemulsification cataract surgery can lead to potential surgical complications. The purpose of this study was to quantify occlusion break surge and vacuum rise time of current phacoemulsification systems used in cataract surgery. METHODS Occlusion break surge at vacuum pressures between 200 and 600 mmHg was assessed with the Infiniti® Vision System, ...

We described simultaneous observations of a surge in Hβ and an X-ray jet in NOAA 8100 on November 1, 1997. We found that the Hβ surge was spatially coincident with the X-ray jet. They occurred at the site where the pre-existing magnetic flux was “cancelled” by a newly emerging flux of opposite polarity. At the base of the surge we identified surge-flaring in the Hβ filtergrams, and both blueshi...

The hundredfold speedup in glacier motion in a surge of the kind the kind that took place in Variegated Glacier in 1982-1983 is caused by the buildup of high water pressure in the basal passageway system, which is made possible by a fundamental and pervasive change in the geometry and water-transport characteristics of this system. The behavior of the glacier in surge has many remarkable featur...

OBJECTIVE To determine the mean morning surge (MS) in blood pressure, the frequency of increased morning surge in normotensive subjects, and to compare those with morning surge with those without MS. STUDY DESIGN Across-sectional, comparative study. PLACE AND DURATION OF STUDY The Department of Medicine, The Aga Khan University Hospital, Karachi, from April 2011 to March 2012. METHODOLOGY...

For more than a decade, emergency medicine (EM) organizations have produced guidelines, training, and leadership for disaster management. However, to date there have been limited guidelines for emergency physicians (EPs) needing to provide a rapid response to a surge in demand. The aim of this project was to identify strategies that may guide surge management in the emergency department (ED). A...
