Abstract In this study the impact of extreme cyclones on Arctic sea ice in summer is investigated. Examined particular are relative thermodynamic and dynamic contributions to volume budgets vicinity 2012 2016. Results from investigation illustrate loss cyclone trajectories during each year were associated with different dominant processes: (melting) Pacific sector 2012, both processes Compariso...

We shed new light on the short-term dynamic effects of cyclones local economic growth in India. proxy GDP with night-time intensity data and construct a cyclone index that varies across months districts depending wind speed exposures. Using projections highly granular for period 1993M1-2011M12, we find yearly estimations hide large differential impacts negative impact is largest between 4 8 aft...

A novel method is introduced to generate climatological frequency distributions of meteorological features from gridded datasets. The method is used here to derive a climatology of extratropical cyclones from sea level pressure (SLP) fields. A simple and classical conception of cyclones is adopted where a cyclone is identified as the finite area that surrounds a local SLP minimum and is enclose...

The objective of this paper is to assess post-cyclone livelihood capitals status, identify major livelihood groups, adversity and crisis, and present the livelihood strategies of coastal households. Based on a questionnaire survey at household level, a total 331 out of 792 households are selected through simple random sampling from three purposively selected villages in the central coast of Ban...

The Atlantic Surface Cyclone Intensification Index (ASCII) is a forecast index that quantifies the strength of low-level baroclinicity in the coastal region of the Carolinas. It is based on the gradient between the coldest 24-h average air temperature at Cape Hatteras and Wilmington, North Carolina, and the temperature at the western boundary of the Gulf Stream. The resulting prestorm baroclini...

Many places around the world are exposed to tropical cyclones and associated storm surges. In spite of massive efforts, a great number of people die each year as a result of cyclone attacks. To mitigate the damages caused by cyclones, improved cyclone forecasting techniques must be developed. The technique presented here uses artificial neural networks to interpret NOAAAVHRR satellite images. A...

Cyclones continue to pose a dangerous threat to the coastal populations of Bangladesh, despite improvements in disaster control procedures. After 138 000 persons died in the April 1991 cyclone, we carried out a rapid epidemiological assessment to determine factors associated with cyclone-related mortality and to identify prevention strategies. A nonrandom survey of 45 housing clusters comprisin...

The specific objectives of the current effort are: 1. To continue our study of the dynamical processes in tropical cyclones responsible for looping or erratic motion; 2. To continue the development of methods for (a) the introduction of synthetic tropical-cyclone-scale vortices in operational forecast models and (b) ensemble forecasting of tropical cyclones; 3. To continue a sensitivity study o...

We find that long-period variations in tropical cyclone and hurricane frequency over the past century in the North Atlantic Ocean have occurred as three relatively stable regimes separated by sharp transitions. Each regime has seen 50% more cyclones and hurricanes than the previous regime and is associated with a distinct range of sea surface temperatures (SSTs) in the eastern Atlantic Ocean. O...

The traditional cyclone with spray scrubber was developed for the removal of airborne silica particles from local exhaust ventilation (LEV). The objective of this research is to evaluate the efficiency of this process for removing silica particles in LEV. After designing and installing a traditional cyclone and spray scrubber, air samples were obtained at the inlet and outlet of the apparatus. ...
