What's behind the heatwave?
Australia heated up this week ½Å¹ß·¹Çø®Ä«»çÀÌÆ®=½Å¹ß·¹Çø®Ä«»çÀÌÆ®
as a mass of hot air swept east across the ¼ÛÆÄ¿ø·ëÀÌ»ç
continent.

The dominant climate ¹æÇе¿¿ë´ÞÀÌ»ç
driver behind the heat has been a positive Indian Ocean Dipole (IOD) - an event where sea surface ¾çÆò¿ë´ÞÀÌ»ç
temperatures are warmer in the western half of the ocean, cooler in the ¼­°æ´ëÆ÷ÀåÀÌ»ç
east.

The difference between ³²ÀÚ·¹ÇÃ=³²ÀÚ·¹ÇÃ
the two temperatures is currently the strongest in kgitbank=¾ÆÀÌÆ¼¹ðÅ©Á¾·ÎÁ¡
60 years.

The warmer waters cause higher-than-average ´ä·Ê¶±=´ä·Êǰ ´ä·Ê¶± Çà»ç¶± ±îÄ¡¶±
rains in the western Indian Ocean region, leading to flooding, and drier conditions across South East Asia and Australia.
