Weather and Climate Interactions Report – April 2021

April 14, 2021 10:39 am Published by Comments Off on Weather and Climate Interactions Report – April 2021

Welcome to the first Weather and Climate Interactions RP report. The new program name is simply a result of rationalising CLEX’s continuing research program under new headings that more clearly delineate the focus of the work we do.

Research brief: How Central Pacific El Niños affect rainfall over the Murray Darling basin

March 18, 2021 1:16 pm Published by Comments Off on Research brief: How Central Pacific El Niños affect rainfall over the Murray Darling basin

This research around central Pacific El Niños is important for agricultural and water resources planning efforts in the Murray Darling Basin region and may help with seasonal prediction efforts to predict drought‐breaking rain such as occurred in early 2020.

Conferences in the time of COVID

This time last year Kim Reid was planning a Euro-adventure where she would attend a summer school in the Swiss Alps, attend EGU, visit Reading and the Met Office and explore some castles on the side. Now she and her supervisor joke that if case numbers stay low, Kim might be able to visit a university in the same city.

Research brief: Revisiting the 1888 Centennial Drought

January 12, 2021 11:27 am Published by Comments Off on Research brief: Revisiting the 1888 Centennial Drought

To shed more light on short droughts of the past, CLEX researchers took advantage of a newly released dataset from the Bureau of Meteorology to re-examine the infamous Centennial Drought of 1888. Using the new dataset along with historical station data, they analysed monthly rainfall variability across south eastern Australia throughout 1888.

RP4 Variability & Teleconnections report – December 2020

It has been remarkable how much we have achieved in this extraordinarily difficult year. Research coming out of the Teleconnections and Variability program over the past four months has strongly focused on how influences in one part of the world can have direct impacts on another.

Research brief: SSTs create biases in how ENSO appears in CMIP5 models

March 13, 2020 9:49 am Published by Comments Off on Research brief: SSTs create biases in how ENSO appears in CMIP5 models

A new study by CLEX researchers and colleagues shows that CMIP5 models as a group, when forced by observed sea surface temperatures underestimate, these atmospheric feedbacks on average by 23%. This underestimate can be linked to the wrong location at which climate models simulate the most important tropical circulation, called the Walker circulation.

Research brief: Convective extremes don’t always coincide with warm extremes during El Niños

November 25, 2019 12:46 pm Published by Comments Off on Research brief: Convective extremes don’t always coincide with warm extremes during El Niños

This study found in CMIP5 models that are able to simulate both types of events, that convective extremes do not always coincide with warm extremes. The disassociation becomes more distinct under greenhouse warming with higher occurrences of convective extremes than warm extremes.
