Researchers probe warming climate forst puzzle

摘要

Asa Wahlquist reports on the implications of an increase in the number of frosts and what a later frost season in south-eastern Australia means for growers. New research has found since 1960 the frost window has lengthened by as much as three weeks inthe Victorian grain belt and by two weeks in NSW. Frosts in Western Australia have, statistically, remained the same, while eastern South Australian sites are similar to Victoria, and sites in the west of that state are more like Western Australia. CSIRO climate application scientist Dr Steven Crimp has been studying the incidence of frosts across the grain belt between 1960 and 2011, as part of research supported by the Grains Research and Development Corporation.
