The tropics will awaken across northern Australia this week, with huge rainfall totals, thunderstorms, tropical lows and tropical cyclone risk all on the cards.

An active pulse of the Madden-Julian Oscillation will increase the risk of tropical cyclones and thunderstorms in the Australian region over the coming week. The Madden-Julian Oscillation (MJO) refers to a pulse of increased tropical cloud, rainfall and thunderstorm activity that moves through our planet’s atmosphere, from west to east, near the equator. The MJO […]
Large areas of Australia saw an above average number of lightning days this summer, with Melbourne, Canberra and Brisbane all seeing 5 to 6 extra storm days during the season. Australia always sees lots of lightning during summer as hot air, abundant moisture and ample atmospheric instability combine to create ideal conditions for thunderstorms. The […]
Rain and thunderstorms will replace extreme heat over large areas of WA this week, with some places in the state’s north likely to see enough rain to officially mark the start of the wet season.

A positive Indian Ocean Dipole is underway, but this one is unlikely to deliver the textbook dry spring and summer that businesses have come to expect from the pattern. The Bureau of Meteorology officially declared a positive IOD on Tuesday, October 27, which typically like El Niño can cause drier and warmer conditions over parts of […]
Waters off Indonesia have cooled in recent weeks, an indication that a positive Indian Ocean Dipole (IOD) event could be developing. It’s an important climate driver for Australia, and it could shape rainfall and temperatures heading into summer, with flow-on effects for farmers, energy and other industries. What is the Indian Ocean Dipole? The IOD […]
