To assess the impact on health of the cyclone and tidal wave that struck the southern coast of Bangladesh on the evening of 29 April 1991, a team of health professionals visited cyclone affected areas from 4-27 June, 1991. Team members met with health workers and officials of the Government of Bangladesh and with staff pom nongovernmental organizations, and conducted field surveys in two severe...

When building systems for high-volume applications, it is very important to keep costs in check. There are several dimensions that affect total cost of ownership beyond the price per part. These include the power demands of the silicon, total bill of materials (BOM) cost, and the productivity of the engineers who design and test the system. It is important to choose an FPGA vendor that has cons...

The 30–60-day Madden–Julian oscillation (MJO) has been documented in previous research to impact tropical cyclone (TC) activity for various tropical cyclone basins around the globe. TheMJOmodulates largescale convective activity throughout the tropics, and concomitantly modulates other fields known to impact tropical cyclone activity such as vertical wind shear, midlevelmoisture, vertical motio...

To track a cyclone using a single orbiting satellite in a continuous manner is impractical as it has limited spatial and temporal coverage. One solution is to use multiple orbiting satellites for cyclone tracking. However, data from some orbiting satellites do not provide features as useful as other satellites in identifying cyclones. Moreover, satellite data containing strong cyclone discrimin...

Four cyclone concentrators were designed and fabricated to compare their particle separation and concentration behavior, such as the major, minor, outlet, and wall deposition fractions. Two of the cyclone concentrators were the conventional type, with the minor flow tube connected to the particle outlet at the bottom of the cyclone. The others were modified cyclone concentrators with a gap betw...

The effect of adding extra inlet channels on the operation of the Stairmand Cyclone has been investigated numerically. The Reynolds stress model (RSM) and Eulerian-Lagrangian method were used to investigate the complex turbulent flow and cyclone performance. The impacts of one-way coupling and two-way coupling models on the cyclone efficiency and the calculation of cut-off size diameter were ex...

The passing of over three decades since tropical cyclone Tracy devastated Darwin on Christmas Day 1974 provided a reason to reflect upon the progress of numerical weather prediction over that period. Each decade was characterised by major model changes. In Australia, the 1970s saw the operational implementation of a 7-level baroclinic filtered model at a grid spacing of 254 km, with rudimentary...

• The damage to older buildings in the areas suffering the most wind damage was very similar to the damage in the most damaged areas in the Whitsunday Islands from Cyclone Ada in January 1970, Townsville from Cyclone Althea in December 1971, and older buildings in Innisfail from Cyclone Larry in March 2006, not much greater than in the worst affected areas of Cyclone Winifred in 1986, and an or...

Arctic cyclone activity has a significant association with Arctic warming and Arctic ice decline. Cyclones in the North Pole are more complex and less developed than those in tropical regions. Identifying polar cyclones proves to be a task of greater complexity. To tackle this challenge, a new method which utilizes pressure level data and velocity field is proposed to improve the identification...
