Research brief: Nutrient transport via the Indonesian Throughflow

n Wed, 07/30/2014 – 16:58 The maritime continent region (above) is critical to global climate and our ability to understand it.  It is the site of one of the major atmospheric convection centers, where condensation releases remarkable energy, fuelling global atmospheric circulation.  It is also a choke point in the upper …

Changing Antarctic winds create new sea level threat

New research shows projected changes in the winds circling the Antarctic may accelerate global sea level rise significantly more than previously estimated. Changes to Antarctic winds have already been linked to southern Australia’s drying climate but now it appears they may also have a profound impact on warming ocean temperatures under …

Research brief: How ENSO influences eastern Australian rainfall

Climate variability in eastern Australia is strongly related to ENSO. In La Niña summers, eastern Australia typically experiences cooler wetter weather, whereas during El Niño events, summers are generally warmer and drier than average. The relationship between ENSO and rainfall is also non-linear with greater differences in rainfall between La …

No warming hiatus for extreme hot temperatures

Extremely hot temperatures over land have dramatically and unequivocally increased in number and area despite claims that the rise in global average temperatures has slowed over the past 10 to 20 years. Scientists from the ARC Centre of Excellence for Climate System Science and international colleagues made the finding when they focused …

Pacific trade winds stall global surface warming – for now

 Heat stored in the western Pacific Ocean caused by an unprecedented strengthening of the equatorial trade winds appears to be largely responsible for the hiatus in surface warming observed over the past 13 years. New research published today in the journal Nature Climate Change indicates that the dramatic acceleration in winds …

Get used to heat waves: extreme El Nino events to double

Monday, January 20, 2014: Extreme weather events fuelled by unusually strong El Ninos, such as the 1983 heatwave that led to the Ash Wednesday bushfires in Australia, are likely to double in number as our planet warms. An international team of scientists from organisations including the ARC Centre of Excellence for …
