- Summary:
-
"Precipitation falling in multi-day bursts is an important water source for the northern Australian tropics in summer and southern Australia in the cool autumn and winter months. Primary producers of crops and livestock need to plan for these events beyond the 7-day deterministic timeframe during the northern wet season (October - April) and southern wet season (April - November), to aid in their business operations. To coincide with the operational release of a multi-week burst potential forecast product in mid-2022, this report examines the skill of the Bureau's latest sub-seasonal-to-seasonal forecast system, the Australian Community Climate Earth-System Simulator - Seasonal version 2 (ACCESS-S2), released in October 2021, in predicting burst events 1 to 4 weeks in advance, predominantly focusing on northern Australia. We use the Symmetric Extremal Dependence Index (SEDI) as a metric to evaluate the skill of ACCESS-S2 in predicting rainfall bursts, given these are often rare events, particularly throughout the rangelands and sub-arid regions of northern Australia. As well as evaluating the hindcast skill of ACCESS-S2, we also apply the SEDI score to ACCESS-S1, to assess if there has been an appreciable improvement in burst prediction skill between forecast system versions."--Executive summary.
