New paper, just published: Australian Sea Levels – Trends, Regional Variability and Influencing Factors

While there has been significant progress in describing and understanding global-mean sea-level rise, the regional departures from this global-mean rise are more poorly described and understood. In this new paper, which you can view here, we present a comprehensive analysis of Australian sea-level data from the 1880s to the present, including an assessment of satellite-altimeter data since 1993.

We find that After the influence of El Niño Southern Oscillation is removed and allowing for the impact of Glacial Isostatic Adjustment and atmospheric pressure effects, Australian mean sea-level trends are close to global-mean trends from 1966 to 2010, including an increase in the rate of rise in the early 1990s. Given that past changes in Australian sea level are similar to global-mean changes over the last 45 years, it is likely that future changes over the 21st century will be consistent with global changes.

Storm surge animation – Super Typhoon Haiyan

Animation of storm surge of Super Typhoon Haiyan making landfall:

The model predicts maximum surge levels exceeding 5 metres near Tacloban City. The peak surge occurs some time after the cyclone has made landfall. At this point, the winds near Tacloban City change direction from easterly to southeasterly, and the cyclone starts pushing water into San Pedro and San Pablo Bay (i.e. the northwesterly part of Leyte Gulf).
