And sadly, for a state still struggling to recover from the floods further south, it was massive. Let's take a look at exactly how destructive this storm really was and how the people of the north fared. Cyclone_tracy. 1974 Cyclone Tracy. BOM - Australian Climate Extremes-Cyclone. Cyclone Tracy, Christmas 1974 The year 1974 started with tropical cyclone "Wanda" bringing torrential rain and flooding to Brisbane.

It ended with another major Australian population centre being devastated by a cyclone. If Maitland epitomised flooding in Australia, and Ash Wednesday or Black Friday, bushfires, then "Tracy" comes most readily to Australian minds when cyclones are mentioned. Understanding tropical cyclones. Tropical cyclones threaten northern Australia every year.

Understanding tropical cyclones

Recent Australian flooding and cyclonic events can be largely explained by a strong La Niña. However, sea surface temperatures off the northern Australian coast in recent months have been at or near record levels. The extremely high sea surface temperatures are part of a significant warming of the oceans that has been observed in the past 50 years. These pages provide some information about the causes, occurrence and impacts of tropical cyclones. 4 February 2011 | Updated 14 October 2011 Overview Recent Australian flooding and cyclonic events can be largely explained by a strong La Niña.

However, sea surface temperatures off the northern Australian coast in recent months have been at or near record levels. Severe Tropical Cyclone Yasi. 30 January - 3 February 2011 Summary Severe Tropical Cyclone Yasi began developing as a tropical low northwest of Fiji on 29th January and started tracking on a general westward track.

Previous Tropical Cyclones. The Australian Tropical Cyclone Database Details of all tropical cyclones that are known to have occurred are contained in a database maintained by the Bureau of Meteorology.

After a tropical cyclone has occurred, tropical cyclone meteorologists reanalyse the cyclone and compile what is known as the 'best track' and a report. Cyclone. Sky Diary KIDSTORM * facts about hurricanes. Hurricanes are mind-boggling in their size and strength.

Sky Diary KIDSTORM * facts about hurricanes

Modern technology lets us see how big hurricanes are and track them through satellite imagery, while storm-penetrating aircraft measure their strength, in terms of wind speeds and atmospheric pressure. That technology gives us detailed warnings that people a century ago never had. Hurricanes usually form in the tropical zones north and south of the equator, where warm waters offer ample fuel for storm formation. That's where you see convection, where warm air rises and forms clusters of thunderstorms. The Coriolis effect, created by the Earth's spinning motion, may cause this cluster of storms to rotate (counter-clockwise above the equator, or clockwise below), but the system has to be a few hundred miles from the equator for the Coriolis force to exert an effect.

A hurricane can be hundreds of miles across. Anatomy of Katrina. Haiyan’s Displaced—What Now?

Who are the "Hurricane Hunters"?

The brave "hurricane hunters" work for the National Oceanic and Atmospheric Administration (NOAA). Each mission lasts about ten hours, with the crews passing four to six times through the storm. The planes carry radar, sophisticated computers, and weather instruments that determine characteristics such as temperature, air pressure, wind speed, and wind direction inside the hurricane.

The crews also release instruments that measure temperature, air pressure, and wind at different levels as the devices drop through the hurricane toward the ocean. Hurricanes. How Hurricanes Work" As hurricane Sandy made its way to the Eastern coast of the United States in October 2012, meteorologists called the storm unprecedented in terms of its potential for damage and fatalities.

These highly trained men and women fly directly into storms in sensor-packed planes to gather data forecasters need to monitor hurricanes and predict their path. Even though hurricane season is only six months long, it takes year-round preparation... 1. Cataclysmic cyclones. Sandy strikes Eastern Seaboard Hurricane Sandy, sometimes called “Superstorm Sandy,” cruised up the East Coast in October, then made a sharp left to cross the New Jersey coast on Oct. 29, causing wind damage, flooding and deaths across the Northeast. October 29, 2012: A section of US 158 in North Carolina, as Hurricane Sandy makes landfall.

The enormous storm was born in the Western Caribbean on Oct. 22, and at one point was 1,100 miles across, a record for an Atlantic hurricane. Fed by two other weather systems, it created a storm surge and flooding across New York City’s low-lying areas, including parts of Queens and Manhattan. Millions lost electric power, transit systems were shut down, subways and tunnels flooded.
