Study confirms frosts occurring later in WA.. New research has confirmed changes to frost patterns in the Western Australia grainbelt, with frosts occurring later in the year and increasing the risk of damage to maturing grain crops... Mr Crimp said the 'Understanding frost risk in a variable and changing climate' research project had also revealed that severe frost events in WA were more likely to occur when centres of 'ridging high pressure systems' were farther south.

"High pressure systems are usually centered over the Great Australian Bight during summer, and move up towards the centre of the country during autumn... The movement allows low pressure systems to take their place, influencing the development of cold fronts and rainfall... Work by Dr Steven Crimp from CSIRO shows that since 1980 the frequency of very cool months has declined, but at the same time, some grain-growing areas in the east have seen an increase in the number of frost days...

Graphs of temperatures over SE Australia showing an increase in the number of frost days and increased length in the frost season.. The frost season is widening and the number of potential frost days is increasing despite an increase in average temperatures...
