The latest edition of the Proceedings of the Royal Society of Victoria is now online, featuring a new species of calcareous sponge discovered in Geelong, a spectacular new H5 meteorite in Maryborough, an account of Indigenous meteorological knowledge using stellar scintillation, a reclassification of fossil graptolites from the early Bendigonian, a case for regulated investment in a resilient electricity network, an account of the Bureau of Meteorology’s new extreme heatwave event forecasting service, and a discussion on whether a similar service might be required for cold extremes.
Dr Joshua Soderholm has always been intrigued by storms. As a boy, he would sit by a window in his house during the summer to watch storms approaching, and often watched them pass by, missing the house. He couldn’t predict exactly where the storm would hit, and to this day he encounters many challenges in observing and forecasting hailstorms. Hailstorm events account for greater than 30% of losses from ‘catastrophic’ events, and the ten largest hailstorms in Australia caused more than 17 billion dollars’ worth of losses as it can be detrimental to agriculture, private property, and commercial businesses. Our current warning systems rely on surveillance and efficient communication, financial insurance, and a response strategy, but we still have poor ability to forecast large hailstorms or predict the size of hail stones with current radar technology.
