Northern hemisphere and south facing similar weather extremes.
Northern hemisphere and south facing similar weather extremes. When this happens the extreme cold in the northern hemisphere, such as China experienced the worst winter weather in 28 years and the Middle East experienced the worst snow storm in 30 years. In contrast, in the southern hemisphere, an extreme heat wave hit Australia.
The phenomenon that occurs a repeat. It shows normal natural phenomenon takes place, "said Zadrach Ledoufij Dupe of the Meteorological Department, Institut Teknologi Bandung (ITB), when contacted from Jakarta, Thursday (01/10/2012).
Zadrach said statistical data are needed to determine the completeness of the extreme weather phenomena such miserable. There is a possibility of the six components of the climate now increasingly disturbed. It resulted in climate change increase the intensity of extreme weather.
China's Meteorological Agency said, since the end of November 2012, the average temperature of the winter in China 3.8 degrees below zero Celsius, or 1.3 degrees cooler than the average temperature of the previous years. Xinhua news agency reported on Saturday (01/05/2012), the official quoted the China Meteorological Administration, said temperatures this winter worst in 28 years.
A number of countries in the Middle East experiencing extreme cold waves, which cause flash floods in some areas and the worst blizzard.
Jordan, one of the countries in the Middle East, set on Wednesday (01/09/2012) as a national holiday. This is because the weather is very cold. The capital of Jordan, Amman, also covered in snow. Observers say the weather in Jordan, this time the worst snow storm in 30 years.
Conversely, extreme hot weather, take place in some parts of Australia, including Tasmania, Victoria, New South Wales, and Queensland. Today thousands of people displaced by the Australian heat wave caused the fire. Tens of thousands of animals become victims of a raging fire.
The highest temperature on Friday (01/04/2012), in the capital city of Tasmania, Hobart, reached 41.8 degrees Celsius. This is the highest temperature since weather records do the early 1880s.
Extreme cold weather periods occurred in China and the Middle East. However, the record-breaking occurs in extreme hot weather conditions with the highest temperature in Australia.
Six components
Zadrach explained, the six components of climate change include the atmosphere (air), lithosphere (land), hydrosphere (water), cryosphere (ice cover), biosphere (living things), and humanosfer (human). Causes of extreme weather in general can be attributed to terusiknya one or more of the six components of the climate.
Humanosfer, according Zadrach, is a component of human-induced climate change is currently the most part. However, pointing to the exact cause of extreme weather is not that simple.
Head of Climate Change and Air Quality at the Meteorology, Climatology, and Geophysics (BMKG) Aldrian Edvin said, natural phenomena such as Rossby waves in the polar regions to temperate Europe moves to the east.
"The phenomenon of the movement of Rossby waves that give rise to a wave of cold and cold weather in parts of Russia and China to floods and snowstorms in the Middle East," said Edvin.
There is not sufficient data to designate the exact cause of extreme weather events, such as the average temperature of the winter in China to 3.8 degrees below zero Celsius, or 1.3 degrees cooler than the previous average.
Worst snowstorm in 30 years in the Middle East can be explained. Edvin said the phenomenon could be due to a snow storm surges cold (cold seruak).
Seruak cold wind is the movement of cold high pressure area to a warmer area to a lower pressure. The difference in air pressure cause air flow. The difference in pressure is high enough can cause the air flow to the strong winds that continued into the blizzard.
Flash floods triggered condensation in the Middle East due to the meeting of cold and hot air. Condensation causing rain.
When the mass of water vapor condensation results from cold seruak plentiful, there was heavy rain. This is a cause flash flooding, as occurred in the West Bank, Palestine, Tuesday (8/1). Two women who were riding a taxi in the West Bank was killed by a flash flood.
While the hot temperatures in Australia, Edvin said, it is because the air is dry in the southern Australia is receiving sunlight while in the south near the equator. The fire was easily ignited.
Climate variability and weather increasingly tense. In order not to further torment, according Zadrach, humans should reduce errors and does not disturb the six components of the climate
