Research brief: Warm Atlantic Water explains sea ice melt north of Svalbard

August 3, 2020 5:05 pm Published by Comments Off on Research brief: Warm Atlantic Water explains sea ice melt north of Svalbard

Northwest of Svalbard, north of Norway, an area known as Whalers Bay stays ice‐free in winter despite the negative air temperatures. It has been assumed that this open water is maintained by inflow of warm Atlantic Water along Svalbard’s west coast; however, this mechanism has never been demonstrated quantitatively -till now.

Research brief: The biogeochemical structure of Southern Ocean mesoscale eddies.

August 3, 2020 4:48 pm Published by Comments Off on Research brief: The biogeochemical structure of Southern Ocean mesoscale eddies.

CLEX researchers used real-world observations with satellite observations to calculate the quantity of nutrients carried into the Subantarctic Zone by mesoscale eddies. They found these eddies carried high nitrate and low silicate waters into the Subantarctic Zone.

How climate change impacts prescribed burning days

July 29, 2020 11:52 am Published by 3 Comments

Climate change will affect prescribed burning days in the future. Unexpectedly, it is not all bad news, but as the coming century progresses there are definitely changes ahead for our firefighters in Australia when it comes to preparing for a fire season, especially along the east coast of Australia.

Need for prediction of marine heatwaves

CLEX researchers and colleagues have highlighted the need for the development of systems to predict marine heatwaves, which are a growing threat to marine ecosystems and industries as the climate changes.

International analysis narrows range of climate’s sensitivity to CO2

July 22, 2020 12:38 am Published by Comments Off on International analysis narrows range of climate’s sensitivity to CO2

The most advanced and comprehensive analysis of climate sensitivity yet undertaken has revealed with more confidence than ever before how sensitive the Earth’s climate is to carbon dioxide. The range has been reduced from 1.5°C-4.5°C down to 2.3°C-4.5°C.

Research brief: How salty seawater can tell us whether to expect rain

July 10, 2020 1:10 pm Published by Comments Off on Research brief: How salty seawater can tell us whether to expect rain

Ocean salinity could be an indicator of major rain events before IOD or ENSO events have peaked. This raises the prospect that long term forecasts for Australia could be improved by analysing sea surface salinity in the Indian and Pacific oceans.

Research brief: New Metrics for Assessing Small Scale Wind Processes in Bureau Forecasts

July 9, 2020 9:59 am Published by Comments Off on Research brief: New Metrics for Assessing Small Scale Wind Processes in Bureau Forecasts

In this paper, CLEX researchers developed new metrics to assess whether forecaster edits targeting these processes were reducing error in the daily varying component of the wind forecasts, by comparing edited and unedited forecast data with weather station observations.

Research brief: The shortcomings of convection-resolving models

July 3, 2020 3:53 pm Published by Comments Off on Research brief: The shortcomings of convection-resolving models

A new paper by Martin Jucker and colleagues reveals the choice of a particular convection-resolving model (CRM) has a much larger impact on the results than increasing resolution. It also suggests the behaviour of CRMs is tied to model internals instead of the phenomena they are trying to reproduce.
