Tropical Cyclone Bune & Cyclones in General - August 19, 2010 by dharkanjhel

The storm not to take so lightly is one called tropical cyclone Bune. Average winds are now somewhere between 75 and 90 MPH, and the storm is fluxuating between tropical storm material to a Category 1 Cyclone. Presently, it appears  that the system will stay away from major land masses.

What do we know generally about cyclones?


What are cyclones?

Cyclones ( or more properly called Tropical Cyclones) are a type of severe spinning(rotating) storm that occurs over the ocean near the tropics.
The word “Cyclone” just means ‘turning wind with one eye. It relates to the word “Cyclops” that one eyed creature in an Ancient Greek story.

Tropical Cyclones have a number of characteristics like:

  • They must have a wind speed greater than 119km/h
  • They start in the tropics.

Did you know that cyclones are actually the release of stored solar energy that rotates. The sun heats the ocean up and this creates the condition for a tropical cyclone to develop.
Cyclones spin because the Earth is spinning. It’s due to something called the coriolis effect.
The direction they spin depends on which hemisphere they are in.
In the Southern hemisphere they spin in a clockwise direction and Northern hemisphere they spin in an anti-clockwise direction.



Did you know…
cyclones are also called hurricanes around the US. Cyclones are called typhoons near the South China sea (from the chinese word meaning ‘big wind’ )

Why are cyclones important ?
There are some obvious reasons for knowing about cyclones, these include:

  • Environmentally cyclones can be important to local ecosystems. eg reefs and the distribution of plants and sand have adapted to them.
  • Cyclones can have a economic and emotional effect on people and property directly affected. thousands of people have died or been displaced by them. Hundreds of homes could be destroyed causing millions of dollars damage.
  • Having a better understanding of cyclones can help you better prepare and perhaps minimise or prevent cyclcone damage.

Cyclones and Culture
Cyclones, like other natural disasters, have an impact on our culture, inspiring films and stories and even names of sporting teams.

How do cyclones occur or form?

The formation of a cyclone has a number of stages
Stage 0 (Zero)- The right place and the right sea temperature is needed.

  • The place is usually within + or – 5° to °15 Lattitude from the equator over the ocean.
  • The surface temperature of the ocean/sea needs to be 26.5°C or above.
  • A low airpressure system (depression) with convection currents starts to gather clouds/stormy

Stage 0 is basically continuous cloud build up even during the night time. The sun sun helps to heat the ocean and produces water vapour that forms couds.

Stage I is linked with a low air pressure system that starts to pull clouds in and rotate. It’s not quite a cyclone but pretty likely.

Stage II is at the stage when the clouds start to really rotate but there is sometimes a chance that it may not develop in to a full cyclone.
After stage II the cyclone is mature and developed, it may increase in size or decrease. It can be in it’s full maturity stage. (image of TC Bonnie /NASA)


The cyclone seasons

  • The northern hemisphere is: June – November
  • The southern hemisphere is: November -May

How do cyclones progress?

Often once the cyclone starts out small and starts to grow larger as it moves towards the north or south.
Destructive Cyclones don’t last more than a few days as their energy runs out. Although it can pick up energy as it travels across warm water.
The low air pressure tends to ‘drag’ material around, eg clouds and moisture from the ocean.
Predicting the direction of a cyclone is very difficult for more than a few hours ahead in time. They can sometimes change direction very quickly(doing a hair pin turn) or just move in fairly straight line.

When a cyclone moves overland they usually lose most of their energy but can cause floods.

     


How are cyclones classified?
The more common scale is the one for measuring typical likely damage. This is based on the Saffir-Simpson Hurricane Scale

Category Wind gust speed/ Swell Damage
1 less than 125km/h
1.2-1.6m
mild damage
2 126-169km/h
1.7-2.5m
significant damage to trees
3 170 – 224km/h
2.6 -3.7
structural damage, power failures likely
4 225 – 279 km/h
3.8-5.4
most roofing lost
5 more than 280 km/h
more than 5.4m
almost total destruction

Cyclones are classified based on information from satellite images and uses a scale called the Dvorak Number going from 0 to 8.

What is the history of cyclones?

Cyclones have existed for as long as the history of the Earth with water.
So it is hard to say when the first hurricane or cyclone was recorded. It is likely that if you looked at some Ships logs from a few hundred years ago it is likely that they recorded cyclone conditions, although many simply would not have survived.
“The Bathurst Bay Hurricane occurred in March 1899. Over 300 people were killed. It was the worst ever cyclone-related disaster in Australia’s history” From BOM

Historic Cyclones

The most famous Australian historic Cyclone was Cyclone Tracy, December 1974, where around 49 people died in Darwin, Northern Territory. There were another 16 who died at sea more… (from ABC news) but this has been revised with another 6 more lost at sea…more… making total of 71.
The US has a long history of Hurricanes that are documented because they often affected populated areas.

Historic Hurricane Hunters

The first Hurricane hunter or person who flew an aircraft into a hurricane , may have been by a man called Joe Duckwork. More…

The future of cyclones.


Cyclones will continue to play a part of the natural cycles on Earth.
The future of cyclones is really about the ability to better predict their intensity and direction.
It is about being able to prevent future injury to people affect by them.

Perhaps a future prospect is to be able to disrupt a cyclone, or change its’ direction to avoid populated areas, but this would require technologies we have not yet developed.
satellite technology and computer modelling of weather is likely to be a key in helping to provide early detection of cyclones.

Survivor art - August 16, 2010 by dharkanjhel

Drawing of Treblinka by Samuel WillenbergWillenberg’s drawings are an attempt to preserve the memory of a terrible place

Israel is marking Holocaust Remembrance Day, commemorating the murder of six million Jews by the Nazis during World War II. Samuel Willenberg, who is now 87 years old, is one of the last two known survivors of the Treblinka extermination camp.

Treblinka was one of the most notorious Nazi death camps.

Part of the Nazis’ “final solution”, the camp in occupied Poland was dedicated to extermination, designed for efficient mass murder.

Between 1942 and 1943 around 870,000 Jews were killed there, according to Israel’s Holocaust Memorial, Yad Vashem.

Not many of those who were sent to Treblinka lived to tell the tale.

Yad Vashem estimates that a few hundred people escaped from the camp, but only a few dozen of those survived the war.

Samuel Willenberg was one of the survivors. His two sisters were killed there.

Sitting in his flat in Tel Aviv, Mr Willenberg, who has written a book about his experiences, said he wanted to give testimony about “the tragedy that was Treblinka”.

Samuel Willenberg

Most people were sent straight to the gas chambers, he said.

There was “no selection, no procedure, no special striped clothes like in Auschwitz”.

“Here we wore the clothes that we found after people were sent to the gas chambers and that’s all. It was death.”

Memories of escape

But a chance encounter saved him from being killed on his first day in the camp.

He recognised one of the Jewish prisoners forced to work in the camp and asked him what he should do. “Say you are a builder, say you are a builder,” the man told him.

As a result, Mr Willenberg said, he was “the only one that remained alive” from his transport.

Samuel WillenbergSamuel Willenberg says he was the only person who survived from his transport to Treblinka

“I was in shock. I couldn’t believe what was happening before my eyes. It is difficult to grasp that suddenly people arrived and other people came and killed them by gas.”

In the basement of his apartment building is a collection of bronze sculptures, created by Mr Willenberg to reflect his experiences in Treblinka and to preserve the memory of those who died.

One is of a girl with her head half-shaved. Another shows a father helping his son take off his shoes before being sent to the gas chamber.

On the wall are his drawings of the camp.

Mr Willenberg believes his sketch of the so-called Lazarett, or field hospital, where some prisoners were shot in the head, is the only eyewitness drawing to survive.

The Germans prevented anyone from making a record of it,” he said.

Looking at his work, he paused in front of one group of figures representing the uprising in the camp against the Germans on 2 August 1943 – the day he escaped.

“Here I put the heroes of Treblinka,” Mr Willenberg said.

Several of the figures brandished guns, but he sought out the one of a man lying on the ground, next to an overturned pram. He stroked it again and again.

A sculpture by Samuel WillenbergHe has also immortalised those who helped and those who fought against the Nazis

“Alfred Boehm, my friend,” he said.

“He helped me and took me out of the line that was taking us on to the gas. He fell in the uprising, he brought us guns and fell – and in his memory, I put him here.

Mr Willenberg was shot in the leg as he left the camp, climbing over the bodies of those who had already been gunned down.

“I ran straight ahead, alone. I wasn’t afraid of being alone. The important thing was to escape.”

He joined the Polish underground and fought against the Germans.

In 1950 he came to Israel.

Now he hopes his statues can one day be part of a museum at Treblinka.

The Holocaust casts a long shadow over Israel, which was founded three years after the end of World War II.

For survivors like Samuel Willenberg, the message is clear: never forget.

Recap 4: Response and Support Efforts for Southern U.S. Tornadoes and Severe Storms
 - August 14, 2010 by dharkanjhel
Posted by: Public Affairs

Since the deadly tornadoes first struck parts of the country last week, the federal government has been in constant contact with all of the impacted states as they responded to and began recovery efforts from these devastating storms.

At the request of the respective governors, FEMA currently has personnel on the ground in Alabama, Georgia, Mississippi, Kentucky, Tennessee and Virginia, and commodities strategically pre-positioned in the region to support the states.

Today, Department of Homeland Security Secretary Napolitano, Housing and Urban Development Secretary Donovan, Agriculture Secretary Vilsack, Small Business Administrator Mills, and FEMA Administrator Fugate, along with American Red Cross President and CEO Gail McGovern, traveled to Alabama and Mississippi to survey the damage and meet with state and local officials.

Recap for Sunday, May 1st

  • President Obama Cabinet members Secretary Napolitano, Secretary Donovan, Secretary Vilsack join Administrator Fugate, Small Business Administration Administrator Mills, American Red Cross President and CEO Gail McGovern and other state and local officials to tour affected areas in Birmingham, Alabama and Smithville, Mississippi.
  • Tonight, the President declared a major disaster for the State of Tennessee and ordered Federal aid to supplement State and local recovery efforts in the area struck by severe storms, tornadoes, straight-line winds, and associated flooding during the period of April 25-28, 2011.
  • Six disaster recovery centers (DRCs) open.  These are staffed by state, voluntary agency and federal personnel to help those whose homes or businesses were affected by recent storms and tornadoes. The centers will be open from 7 a.m. to 7 p.m. seven days a week until further notice.  At the DRCs, representatives from FEMA, state and other agencies meet one on one with disaster survivors, explain assistance programs and help survivors apply for disaster aid.
  • More than 150 inspectors are on the ground in Alabama, Mississippi and Georgia assessing damages in order to help applicants to receive financial assistance. The number of field inspectors is expected to increase rapidly over the next several days.
  • FEMA Community Relations (CR) personnel are on the ground in Mississippi, joining CR teams already deployed previously to Georgia and Alabama, to meet with disaster survivors to explain the assistance available and to help survivors register for assistance. 
  • National Voluntary Organizations Active in Disaster (National VOAD) member organizations such as American Red Cross, Salvation Army, Convoy of Hope, and many others continue to be heavily involved in the disaster response by providing assistance to disaster survivors. The Red Cross Safe and Well secure website provides a way for people to find information on people affected by the storms. To register, visit www.redcross.org/safeandwell. Open Red Cross shelters can also be found on www.redcross.org.     
  • The Alabama Governor’s Office of Faith Based and Community Initiatives and Mississippi Commission for Volunteer Service have set up official web portals to help with coordinating donations and volunteers.  Cash is the preferred method of donation in order to ensure that disaster survivors get the services and supplies they need quickly.

Tropical Cyclone BUNE, Unpredictable - August 13, 2010 by dharkanjhel
Tropical Cyclone BUNE (13F) (19P), Severity Category 2 
About 340 nm South-Southeast of Nadi, Fiji, 
Drifting South-Southwestward at 2 knots
Active – Weakening, Saffir-Simpson Category 1

Tropical Cyclone BUNE (13F) (19P), Severity Category 2 
About 340 nm South-Southeast of Nadi, Fiji,
Drifting South-Southwestward at 2 knots 

(977 hPa, 60 kt [111 km/hr] [10-minute sustained] – RSMC Nadi, 0000 UTC 26 March 2011)
(974 mb, 65 kt [120 km/hr] [1-minute sustained] – JTWC, 0000 UTC 26 March 2011)
(Position Fix 22.9S, 180.0W at 0232 UTC 26 March 2011)

This storm is one of the most unpredictable of the season so far in 2011. Indications are that the storm is weakening, but this storm has been very unstable, with winds gaining, but then subsiding. The path of the storm is not as predicable as most other storms. Presently, the storm is about 340 Nautical miles South-Southeast of Nadi, Fiji, and it is drifting South-Southwestward at 2 knots. The knot is a unit of speed equal to one nautical mile (which is defined as 1.852 km) per hour, approximately 1.151 mph. Some may consider the slow speed a good thing, but others may consider it a bad thing. The storm is in very open waters presently, and it will stand a chance of gaining in strength as it will continue to pull warm moisture from the surface of the ocean. But it is still unpredictable at this time. The storm has been drifting between a Category 1 and Category 2 for the last few days.
