Tropical cyclone

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 29th of January 2011, and started tracking on a general westward track. It quickly intensified to a cyclone category to the north of Vanuatu. It then rapidly intensified to a Category 2 by 10am 31st January, then a Category 3 by 4pm on the same day. Yasi maintained Category 3 intensity for 24 hours, then was upgraded to Category 4 at 7pm on 1st February. During this time, it started to take a more west-south-westward movement and began to accelerate towards the tropical Queensland coast. At 4am 2nd February, Yasi was upgraded to a marginal Category 5 system. Yasi made landfall on the southern tropical coast near Mission Beach between midnight and 1am on 3rd February. It maintained a strong core with damaging winds and…

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?…

Blocking highs Blocking highs are strong high-pressure systems that form further south of Australia than normal and remain almost motionless for a long amount of time. Blocking highs mostly affect southern Australia, they can take place during any time of the year and can last from several days - several weeks. Blocking highs can impact Australia in numerous ways depending on where they occur and how strong they are, they are able to produce hot and cold spells as well as wet conditions and dry…

and high altitude," ( "Hurricanes, Typhoons, and Cyclones..."). Because of their warm ocean water temperatures, all hurricanes are formed between the Tropic of Cancer( 23.5 degrees north latitude) and the Tropic of Capricorn (23.5 degrees south latitude). Secondly, the formation of a hurricane has four different stages. Hurricanes start off as a bundle of tropical storms known as a tropical disturbance( "Hurricanes, Typhoons, and Cyclones..."). Once the tropical disturbance starts to whip into…

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…

A tropical wave developed into Tropical Storm Nicole about 530 mi (850 km) northeast of San Juan, Puerto Rico, early on October 4, [29] based on an ASCAT pass revealing a well-defined surface circulation and winds of up to 50 mph (85 km/h). The NHC forecast only gradual strengthening as the storm moved slowly to the north due to weak steering currents.[112] An eye then became visible at both mid- and upper-level heights, and Nicole rapidly strengthened to a Category 2 hurricane to the south of…

A tropical storm can change the landscape to the coastal region by destroying areas like the barrier islands and estuaries. Hurricanes can cause erosion in beaches, marsh lands and coastal cliffs, which makes the land more susceptible to damage with future storms. Protecting the coastal regions is highly important because hurricanes threaten coastal residencies and diminish any income gained from tourists. Hurricane Katrina, for example, was responsible for over 108 billion dollars in property…

There have been so many deadly tropical storms, here is a list of the most devastating and costly. One named hurricane Opal hit Florida, Alabama, and Tennessee in 1995. It’s damage cost $5.1 billion. In 2003 hurricane Isabel hit North Carolina and impacted other banks. It costed $5.3 billion. Another was hurricane Floyd which was especially catastrophic because of the rain causing extreme flooding. It hit North Carolina and up the east coast as a Cat. 2 and travelled North. It’s damage was $6.9…

by definition, is a tropical cyclone with strong winds spiraling inward and upward and speeds ranging from 75 mph to 200 mph. Hurricanes emerge from the Atlantic basin, which consists of the Atlantic Ocean, Caribbean Sea, Gulf of Mexico, the northeastern Pacific Ocean, and, less often, the central north Pacific Ocean. Most hurricanes follow a similar cycle of development. Some may run their course in as little as a day or as long as a month. They weaken and are transformed into extratropical…

The 1947 Atlantic hurricane season was the first Atlantic hurricane season to have tropical storms named by the United States Air Force. The season officially began on June 16, 1947, and ended on November 1, 1947. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. However, the first tropical cyclone developed on June 13, while the final system was absorbed by a cold front on December 1. There were 10 tropical storms; 5 of them…
