Science Daily June 23, 2023 Standard climate projections, as in Intergovernmental Panel on Climate Change Sixth Assessment Report, assume that explosive volcanic activity over 2015–2100 are of the same level as the 1850–2014 period. Researchers in the UK used the latest ice-core and satellite records to design stochastic eruption scenarios, to show that there is a 95% probability that explosive eruptions could emit more sulfur dioxide (SO2) into the stratosphere over 2015–2100 than current standard climate projections (i.e., ScenarioMIP). Their simulations using the UK Earth System Model with interactive stratospheric aerosols showed that for a median future eruption scenario, the […]

A new approach to controlling the properties of turbulence
Phys.org June 20, 2023 Material boundaries of the experimental apparatus developed to generate turbulence pose a challenge for understanding what the turbulence has been fed and how it would freely evolve. An international team of researchers (USA – University of Chicago, UC Santa Barbara, France) built and controlled a confined state of turbulence using vortex rings. The stationary and isolated blob of turbulence was sustained solely by vortex rings. Thus they assembled a full picture of its three-dimensional structure, onset, energy budget and tunability. The incoming vortex rings could be endowed with conserved quantities, such as helicity, which could be […]
