The potential use of the National Centers for Environmental Prediction (NCEP) Regional Spectral Model (RSM) for downscaling seasonal tropical cyclone (TC) activity was analyzed here. The NCEP RSM with horizontal resolution of 50 km, was used to downscale the ECHAM4.5 Atmospheric General Circulation Model (AGCM) simulations forced with observed sea surface temperature (SST) over the western Nort...

This paper reports on an experiment to add concurrency to the Cyclone programming language, in order to get a safe concurrent language. The basic model considered is that of FairThreads in which synchronous and asynchronous aspects are mixed. The language Loft implements the FairThreads model in C. In this paper, one uses Cyclone instead of C in the implementation of Loft. Using the multi-threa...

This paper presents the results of studies performed to rehabilitate an existing seawall in Fujairah to withstand cyclone Gonu condition. The exiting section has not been designed for the cyclone Gonu condition. A desktop study was implemented to assess the functionality of the existing section by applying the methods recommended in the applicable standards and guidelines. This assessment sho...

For generations, cyclones and tidal surges have frequently devastated lives and property in coastal and island Bangladesh. This study explores vulnerability to cyclone hazards using first-hand coping recollections from prior to, during and after these events. Qualitative field data suggest that, beyond extreme cyclone forces, localised vulnerability is defined in terms of response processes, in...

The kinetic energy budgets of several examples of synoptic scale systems are reviewed. Included are systems containing a major cyclone development, the immediate cyclone vicinity, and the anticyclone preceding the cyclone development. These are then considered in terms of their role in the general circulation of the middle latitudes. Results show that the cyclone system and cyclone vicinity are...

"Pre-separator plus1D2D cyclone" and "pre-separator plus 1D3D cyclone" systems were tested with ground gin trash, which contains 10.35% lint fiber and 5.49% fine dust (less than 100 μm). Test results indicate that the pre-separator collected gin trash at over 97% collection efficiency. There were no significant differences in emission concentrations and overall collection efficiencies from thes...

[1] Tropical cyclone accumulated cyclone energy (ACE) has exhibited strikingly large global interannual variability during the past 40‐years. In the pentad since 2006, Northern Hemisphere and global tropical cyclone ACE has decreased dramatically to the lowest levels since the late 1970s. Additionally, the global frequency of tropical cyclones has reached a historical low. Here evidence is pres...

Entrained flow gasification of biomass using the cyclone principle has been proposed in combination with a gas engine as a method for combined heat and power production in small to medium scale (<20 MW). This type of gasifier also has the potential to operate using ash rich fuels since the reactor temperature is lower than the ash melting temperature and the ash can be separated after being col...

The properties of tropical cyclones in three low-resolution atmospheric general circulation models (AGCMs) in seven ocean basins are discussed. The models are forced by prescribed, observed sea surface temperatures over a period of 40 yr, and their simulations of tropical cyclone activity are compared with observations. The model cyclone characteristics considered include genesis position, numb...
