Research brief: How El Niños impact climate in the southwest Indian OCean

March 9, 2021 3:13 pm Published by Comments Off on Research brief: How El Niños impact climate in the southwest Indian OCean

El Niño effects are communicated to the Indian Ocean via both large‐scale atmospheric circulation changes over the southern tropical ocean basin and via disturbances to sea‐levels along the coast of Western Australia. CLEX researchers investigated these remote ENSO influences in a state‐of‐the‐art climate model.

Business risk and the emergence of climate analytics

February 15, 2021 1:22 pm Published by Comments Off on Business risk and the emergence of climate analytics

There is a great deal of misuse of climate model projections emerging in business. Climate models are being used for some purposes that are simply inappropriate leading to assessments of the physical risks to business that are of no value. However, there are ways to use climate model data that has value and can help business robustly assess some specific climate related risks.

Research brief: How gravity waves impact thunderstorm formation

February 11, 2021 10:14 am Published by Comments Off on Research brief: How gravity waves impact thunderstorm formation

Storms cause ripples in the wind that travel upwards and away from the clouds, much like a stone causes ripples when it is thrown in a pond. These can then affect the temperature and winds around the storms and make them grow, last longer, or die earlier.

Research brief: Southern ocean overturning circulation responds to SAM

January 15, 2021 9:49 am Published by Comments Off on Research brief: Southern ocean overturning circulation responds to SAM

CLEX researchers introduced a novel methodology to examine the Southern Ocean's response to changing winds. They performed numerical simulations with a global ocean‐sea ice model suite that spans a hierarchy of spatial resolutions and driven by realistic atmospheric forcing conditions.

Research brief: The interaction of ocean basins may improve long-term climate predictions

December 17, 2020 10:58 am Published by Comments Off on Research brief: The interaction of ocean basins may improve long-term climate predictions

An international team of authors led by NCAR scientist and CLEX PI Jerry Meehl, along with CLEX CIs and AIs, propose that the Pacific and Atlantic ocean basins are mutually interactive, with each basin influencing and responding to processes in the other basin.

RP4 Teleconnections & Variability Report – December 2020

December 14, 2020 11:45 am Published by Comments Off on RP4 Teleconnections & Variability 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.

RP3 Drought Report – December 2020

December 14, 2020 11:01 am Published by Comments Off on RP3 Drought Report – December 2020

A major component of the research in the Drought program over the past four months has focused on the interface between real-world data and climate models. The aim of much of this research has been to improve how land surface models represent some of the key processes that influence the length, and severity of drought.

RP1 Extreme Rainfall Report – December 2020

Despite what has been a very challenging year, the Extreme Rainfall research program continues to produce high-quality research, develop deep and wide datasets, extend the reach of our citizen science, and has seen our researchers continue to achieve at a national and international level.

Research brief: tropics and SOUTHERN HEMISPHERE subtropics were drier in the mid‑Pliocene Warm Period

November 2, 2020 2:28 pm Published by Comments Off on Research brief: tropics and SOUTHERN HEMISPHERE subtropics were drier in the mid‑Pliocene Warm Period

New study shows November-to-March precipitation (when rainy season peaks over most of the Southern Hemisphere land mass) was significantly reduced both in the Southern Hemisphere tropics and subtropics due to a weakening of the subtropical convergence zones during the mid-Pliocene Warm Period.
