 Why has this happened now?

Several individual <a href="https://kkwii8w88.tistory.com/134" target="_blank">¿ë¹®µ¿¿ë´ÞÀÌ»ç</a><br /> heat records for 
towns and cities have already been shattered. On Tuesday, places across the nation's centre recorded temperatures <a

At the start of the week, Perth, the <a href="https://spred.tistory.com/26" target="_blank">Àá½ÇÀÌ»ñÁü¼¾ÅÍ</a><br /> capital of 
Western Australia, recorded three days in a row above 40C - a record for December.

The dominant climate driver <a href="https://sowoe33902.tistory.com/138" target="_blank">¿À»êÆ÷ÀåÀÌ»ç</a><br /> behind the 
heat has been a positive Indian Ocean Dipole (IOD) - an event where sea surface temperatures <a href="http://itbank-
eduone.co.kr/" target="_blank">kgitbank</a>=¾ÆÀÌƼ¹ðÅ©Á¾·ÎÁ¡<br /> are warmer in the western half of the ocean, cooler in 
the east.

The difference between the two temperatures <a href="http://kachi.co.kr/" target="_blank">´ä·Ê¶±</a>=´ä·ÊÇ° ´ä·Ê¶± Çà»ç¶± ±î
Ä¡¶±<br /> is currently the strongest in 60 years. The warmer waters cause higher-than-average rains in the western Indian 
Ocean region, leading to flooding, and drier conditions across South East Asia and Australia.
