A pulse in a lesser-known tropical wave will bring increased risk of tropical cyclone activity over northern Australia in the coming week. What are tropical waves? Earth’s tropical atmosphere contains a number of large-scale waves that influence cloud and rainfall patterns throughout the year. The most well-known tropical wave is called the Madden-Julian Oscillation (MJO), […]
A powerful Tasman Low spinning off Australia’s East Coast is whipping up large waves along coastal NSW.

A series of very long period swells will bring deceptively powerful waves to NSW ports. Image: Satellite loop of powerful lows well to the south of Australia on Monday, March 17. A very active period with powerful low pressure systems crossing well to the south of Australia over the past weekend and early week have […]
Australia’s tropics will be invigorated by a pulse of the Madden-Julian Oscillation (MJO) this week, increasing the risk of tropical cyclone activity near Australia. A surge of monsoonal winds crossing the Maritime Continent will cause an injection of moisture-laden air into the tropics near Australia over the coming week. This monsoon burst will coincide with […]
East Asia experienced significant drops in temperatures this weekend, which could lead to flooding rainfall over Indonesia and tropical cyclones in the Australian region. But how?

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 […]
Leonora, WA, had its wettest September day on record earlier this month. Three weeks later, more than 1.3 million lightning pulses were detected within 800 km of the town in 48 hours. Why is a stalled trough delivering storms to mining country, and what it could mean for operations? The DTN Total Lightning Network detected […]
