Dr. Frederiksen made these comments on Monday, July 4, 2011, at a conference of the International Union of Geodesy and Geophysics, being held in Melbourne, Australia.
Frederiksen stated, 'The drop in winter and autumn rainfall observed across southern Australia is due to a large downturn in the intensity of storm formations over at least the last three decades compared with the previous three decades, and these effects have become more pronounced with time."
And, 'Our recent work on climate model projections suggests a continuation of these trends over the next 50 years.'
The conclusions found by Frederiksen and fellow collaborators Drs. Carsten Segerlund Frederiksen, Janice Maria Sisson, and Stacey Lee Osbrough are found within the article 'Changes and Projections in Australian Winter Rainfall and Circulation: Anthropogenic Forcing and Internal Variability' (volume 2, issue 3, pages 143-162).
The paper was published within the The International Journal of Climate Change: Impacts and Responses.
