With the development of climate change and global warming, more and more severe tropical storms, hurricanes and typhoons tend to emerge[nature], leading devastating threat and damage to human lives and social productions. Accurate forecasting of storm track and intensity is of vital importance to help evacuation and hence decrease losses. However, the accuracy of storm forecast heavily depends ...

Sand and dust storms are natural events that occur widely around the world, mostly in dry and bare lands. Over thepast decade a large part of Iran has been affected by this phenomenon, and Tehran has not been excluded from thisevent. Therefore, having knowledge of spatiotemporal frequency variations can aid us in future management andstorm trajectory assessment. In this study the synoptic anemo...

The 1998 Sydney-Hobart yacht race was affected by storm-force winds on the afternoon of 27 December 1998. Of the 115 yachts that contested the race, 71 retired, six were abandoned, and five sank. Fifty-five crew were rescued, and six lives were lost (see Cruising Yacht Club of Australia (CYCA) 1999). These storm-force winds were associated with a mesoscale extratropical cyclone that developed d...

[1] Since 1996 when GPS reflected signals were purposefully acquired, an effort to assess the utility of these signals has been under way. It was early determined that the reflected GPS signal can be related to ocean surface wind dependent slope probability densities. Quantifying that relationship has resulted in considerable data taken at wind speeds below those associated with tropical storms...

The strong correlation between magnetic storms and southward interplanetary magnetic eld (IMF) is well known from linear prediction lter studies using the Dst and IMF data. However, the linear lters change signiicantly from one storm to another and thus are limited in their predicting ability. Previous studies have indicated nonlinearity in the magneto-spheric response as the ring current decay...

Recent dramatic increases in damages caused by tropical cyclones (TCs) and improved understanding of TC physics have led DHS to fund research on intentional hurricane modification. We present a decision analytic assessment of whether it is potentially cost-effective to attempt to lower the wind speed of TCs approaching South Florida by reducing sea surface temperatures with wind-wave pumps. Usi...

Fields of wind velocity, divergence, and reflectivity were derived from Doppler radar measurements in a New England storm over a 6-hr. period. 9 laycr of casterlies near the surfncc increased in depth and speed during the period. Above this layer the wind veered with hcight to SW and W, and then backed to SW. Changes in wind dircction with time in thc layer bctween 4 and 6 km. indicr)ted the pn...

We investigate the rapidly changing equilibrium between the momentum sources and sinks during the passage of a single two-peak storm over the Catalan inner shelf (NW Mediterranean Sea). Velocity measurements at 24 m water depth are taken as representative of the inner shelf, and the cross-shelf variability is explored with measurements at 50 m water depth. During both wind pulses, the flow acce...
