"Although the winds will head in southeastern direction or Australia, the impact of this storm`s tail will be felt among other things in Nusa Tenggara, Bali, Java and Sumatra. This will happen until the cyclone`s landfall," BMKG offical Edvin Aldrian said here Thursday.
At present, Edvin said, cyclone Vince was at 15 degrees southern latitude and 109 degrees eastern longitude moving away from Java. The cause of the tropical cyclone was the hot temperature occurring south of Indonesia or in northern Australia. The phenomenon usually occurs in the December-March period, he added.
As a cyclone, Edvin said, Vince came because there was a low atmospheric area creating seeds of a hurricane which then spinning, swelling and moving hundreds of kilometers per hour, but would be exhausted in a couple of days.
About the flash floods in Queensland, Australia, Edvin said the phenomenon was caused by high sea temperatures in northern Australia as well as by cyclone Vince.
However, he added, the sea temperature in this area nowadays was extremely high reaching 31 degrees Celsius causing flash flood in Australia.
"This year the temperature in northern Australia was very high," he said, adding it was not true that the flood phenomenon was related to La Nina.
The snow that fell in southern Australia during the summer was also the impact from the high sea temperature in northern Australia, he said.
"Because the tropic is hot, the surge is automatically low. So, it pulls the air mass from the highest latitude to the sub polar, causing snow in southern Australia which it never happen even in winter," he said.
He confirmed that Indonesia needed to beware against the phenomenon of extreme hot sea temperature in southern Indonesia; however it did not mean that Indonesia would be hit by flash flood in the near future as happened in Australia.
"It`s so sporadic that it doesn`t mean Indonesia will be hit by flash flood like Australia. It`s sea dynamic," said he while confirming that the flood in Australia was closely related to climate change phenomenon.
