Global Energy Spectrum of the General Oceanic Circulation
Sept. 23, 2022

How big are ocean currents?  That question has been posed by generations of oceanographers, with partial answers available through measurements from ships, satellites, and numerical simulations.  However, the answers were generally limited by methods used to decompose the kinetic energy of ocean currents according to their…

How the South Asian Monsoon is Changing in a Warming Climate
Sept. 21, 2022

AOS Associate Research Scholar Spencer Hill, a CIMES researcher, was co-author on a recent guest post for Carbon Brief on the recent flooding in Pakistan. The authors take a closer look at the south Asian monsoon, how it is being affected by human activity, and how it may change in the future.

The Rapid Growth of Tropical Cyclones’ Outer Size – A New Concept
Sept. 13, 2022

A new study focuses on the rapid growth of tropical cyclones and their destructive potential.

The potential destruction caused by the winds of tropical cyclones (TCs) depends on both intensity and size. A new study, co-authored by AOS Associate Research Scholar Shuai Wang, a CIMES researcher, introduces a…

Impact of Warmer Sea Surface Temperature on the Global Pattern of Intense Convection: Insights From a Global Storm Resolving Model
Sept. 12, 2022

Intense convection has profound consequences for weather and climate. However, it is still unclear how intense convection changes in a warmed climate because traditional climate models are too coarse to explicitly simulate it.

New research led by AOS…

A Simple Conceptual Model for the Self-sustained Multidecadal AMOC Variability
Aug. 30, 2022

Multidecadal variability of Atlantic Meridional Overturning Circulation (AMOC) has been reconstructed by various proxies, simulated in climate models, and linked to multidecadal Arctic salinity variability. However, the mechanisms of the multidecadal AMOC variability and its two-way interaction with the Arctic salinity anomaly, as well as the…

Congratulations to Juho Iipponen for Successfully Defending his Ph.D. Thesis
Aug. 26, 2022

Congratulations to Juho Iipponen who successfully defended his Ph.D. Thesis, "Role of Clouds in Tropical Climate and its Variability,” on August 26.  Juho accepted a computational fluid dynamics developer position at

A New Look at Preindustrial Carbon Release from the Deep Ocean
Aug. 22, 2022

New research could help inform future studies of how the release of carbon dioxide from the Southern Ocean might affect global climate change.

In the Southern Ocean near Antarctica, deep-ocean water upwells to the surface, where it releases carbon dioxide that entered the ocean prior to the Industrial Revolution. This…

Aug. 11, 2022

Congratulations to Houssam Yassin who successfully defended his Ph.D. Thesis, "The Geostrophic Turbulence of Boundary Buoyancy,” on August 11.  Houssam accepted a postdoctoral associate position at the University of Maryland.  We wish him continued success in this new endeavor!

Without Human-Caused Climate Change Temperatures of 40°C in the UK Would Have Been Extremely Unlikely
July 29, 2022

Scientists from South Africa, Germany, France, Switzerland, New Zealand, Denmark, the United States, and the United Kingdom, collaborated to assess to what extent human-induced climate change altered the likelihood and intensity of the recent heatwave in the UK. AOS Faculty Member Gabe Vecchi and Wenchang Yang

UK Forecasters Issue First-Ever 'Red' Warning for Exceptional Heat with All-Time Records Poised to Topple
July 18, 2022

AOS Faculty Member Gabriel Vecchi, deputy director of CIMES, told CNN that this is a signal of the climate crisis, and hot extremes outpacing cool extremes has been a notable trend in recent years.

"This is what you would expect from a planetary warming that's been driven in large part from greenhouse gases; this is…
