Climate Change effects in an Australian context.......
Projected changes to regional
Annual average temperatures will increase between 0.3 to 1.6 degrees C by 2030 and between 0.8 and 5.0 degrees C by 2070.
The frequency of extreme maximum temperatures will increase and that of extreme minimum temperatures will decrease. Less rainfall is likely. Where average rainfall decreases more dry spells are likely and where average rainfall increases, there will be more extremely wet years.
Warmer conditions will to lead to increased evaporation. When combined with the simulated decrease in rainfall, most locations show a decrease in available moisture.
Victorian spring rainfall 1860-2100 as simulated in HadCM3. Horizontal line indicates the average for 1860-1999. Extreme daily rainfall events may become more extreme, even where average rainfall declines. The frequency of low pressure systems increases over the land in summer, and mainly decreases over the surrounding oceans in winter. Although the average intensity of systems decreases, the frequency of the intense systems (storms) is simulated to increase.
