The Cyclone Event Cyclone Megi, or locally know as a typhoon, was first reported as a cyclone at around halfway though October 16 2010. It continued in a north west direction, at around the end of October 16 2010 Megi was upgraded to a category 4 cyclone. For the entirety of October 17 2010 Megi was a level 5 cyclone, the most powerful level. At approximately 11:25 am on the 18th of October 2010 cyclone Megi, currently at a category 5, hit Isabela province. As shown in figure 1.2. The island of Luzon, which is the larger land mass at the most northern part of the Philippines, was were the cyclone hit and did the most damage. Figure 1.0 shows the area were Megi first made landfall. The province of Isabela Prior to the cyclone actually hitting,…

Participation in the early response of Cyclone Nargis: Reflective case study Introduction Myanmar is exposed to multi-hazards such as fire, flood, earthquake, cyclone and landslide. It is situated in tropical climate zone and has three seasons-Summer (mid-February to mid-May), Rainy (mid-May to mid-October) and Winter (mid-October to mid-February). The official cyclone season is in monsoon period and the high potential of cyclone formation is in pre-monsoon and post-monsoon periods. Cyclone…

hydro-meteorological hazards. Approximately, 45 damaging cyclones were reported in the coastal areas of Bangladesh from 1793 to May 1997; therefore the cyclone recurrent period becomes 4.5 years (Shamsuddoha M and Chowdhury R.K, 2007). Hasan. A et al (2013) identified the decadal distributions of cyclones that hit Bangladesh. Source: (Hasan. A et al 2013) Cyclones generally form in Indian Ocean and due to ‘Coriolis Effect’ and the funnel shape appearance of Bay of Bengal basin these hit the…

On February 19th, 2015 cyclone Lam had finally made landfall between Millingimbi and Elcho island in the northern territory as a category 4 cyclone. Cyclone lam had started off as a monsoon trough on February 12th over the Coral sea and moved over the Cape York peninsula and moved to the Gulf of Carpentaria. Due to warm waters and favourable outflow the monsoon trough became a category 1 cyclone on the 16th of February and was named cyclone Lam by the Bureau of Meteorology. Cyclone Lam started…

Severe Tropical Cyclone Yasi occurred in Australia on the 3rd of February 2011. It reached a marginal Category 5. The lowest air pressure was recorded at Tully Sugar Mill at 929 hPa. The heaviest rainfall was recorded at South Mission beach at 471 mm. The highest tidal surge was recorded at Cardwell of an approximate height of 5m. Yasi had a maximum wind gust of 285 km/h, and had a maximum sustained wind gust of 205 km/h. Cyclone Yasi began developing as a tropical low northwest of Fiji on the…

Hurricane Katrina A hurricane is a tropical cyclone that normally occurs in the North Atlantic Ocean, North America and the North-eastern Pacific Ocean. These cyclones normally build up over parts of oceans with relatively warmer water. They derive their body from evaporating water from the ocean which condenses to form clouds and precipitate as rain when the moist air reaches saturation. The motion is imparted to the cyclones by the rotation of the earth. Tropical cyclones rotate…

Cyclones are a spinning and possibly dangerous storm. These storms bring many problems that should be mitigated. These powerful, intense spinning storms cannot be stopped, however some of the negative effects from cyclones can be mitigated. So what are cyclones and where abouts do they form? What are the effects of climate change on cyclones, will the frequency of them change? What are the negative effects and what can be done to prevent these? More awareness should be given out and buildings…

Members from BHP Billiton LTD, have approached filtration consulting, to design a cyclone separator system for a process involved in the production of zinc oxide particles. The clients has also asked for advice on the use of bag filters as a standalone system, or in conjunction with a cyclone separator system. The filtration system must have a collection efficiency of 95% of the zinc oxide particle from a gas flow at 1000°C and with a flow rate of 3820 (Nm^3)/hr. One of the most common particle…

Around the Great Lakes area and the majority of the Northeast temperatures are expected stay 30 degrees below average from the result of the “bomb cyclone”. A bomb cyclone occurs when the atmospheric pressure drops so quickly that the weather system increases rapidly in strength and brings high winds. The pressure has to drop at least 24 millibars in 24 hours to create a bomb cyclone and the storm can cause costal flooding and blizzard like conditions during the winter. The storm, Grayson,…

Tropical Cyclones Cameron Pillay Figure 1.1 Tropical cyclones. One of the wonders of nature that reassures us that god is watching our behavior. Jokes aside, hurricanes, typhoons, cyclones or even willie willies, whatever you prefer, are a massive danger to our society. The harsh winds and floods result in many deaths and major destruction to infrastructure along coastal regions(L. Dilley, J. Earle, K. Euston-Brown, G. Keats, A.Nxele, G. Ravenscroft, 2013). So how can we prepare ourselves?…
