gonu storm was formed in tropical basin of indian ocean early in june 2007. gonu is the strongest tropical cyclone that happened in arabian sea and north indian ocean and moved toward oman sea and persian gulf and bouncing the lands around the area. this tropical cyclone made extensive damages and human and financial causalities to countries of oman, iran, afghanistan, pakistan, and india. in t...

The National Weather Service (NWS), with occasional augmentation by private assessors and universities, often uses damage surveys to determine path characteristics of wind events in general and tornadoes in particular. The results flow into a wide variety of utilizations, primarily involving: • Climatological recordkeeping, including the county-segmented Storm Data listing and its whole-tornado...

The storm Gudrun hit southern Sweden in January 2005 and approximately 70 million cubic meters of forest was wind felled. The existing logistic planning at forest companies in the damaged area had to be changed over night. There was a direct shortage of both harvest and transportation capacities. Key questions that arised were which terminals to use, where to harvest, where to store, which tran...

Forests cover about 56% of the land area in Sweden and forest damage due to strong winds has been a recurring problem. In this paper we analyse recorded storm damage in Swedish forests for the years 1965–2007. During the period 48 individual storm events with a total damage of 164 Mm3 have been reported with the severe storm on 8 to 9 January 2005, as the worst with 70 Mm3 damaged forest. For t...

The potential for a gliding UAV to sustain flight by dynamically soaring in a hurricane is investigated. Leveraging extensive storm observations, the wind profile of the hurricane eye is modeled as a continuous function that is zero at the center and increases as a power of the radius. We then derive the equations of motion for a UAV flying in this wind field, and prove analytically that if the...

The objective is to investigate the physical processes that occur as a tropical cyclone interacts with the environment such that intensity and structure changes occur. Specific interactions being studied are with baroclinic environments in the midlatitudes during extratropical transition. During extratropical transition, radical changes to the storm structure occur as vertical wind shear and in...

Hurricane Sandy was a sobering reminder to those of us who call New York home that it is a port city and subject to the whims of wind and water. The storm itself was massive: climatologically, a thousand miles wide at its peak; economically, an estimated excess of $50 billion in damages. In the New York metropolitan area, 97 people died in the storm, thousands were displaced from their homes, a...
