Sci. Adv., 9 (37),

    Summary from "The planetary boundaries concept presents a set of nine planetary boundaries within which humanity can continue to develop and thrive for generations to come. In September 2023, a team of scientists quantified, for the first time, all nine processes that regulate the stability and resilience of the Earth system." [more...]

(2023) Historical Changes and Reasons for Model Differences in Anthropogenic Aerosol Forcing in CMIP6. Geophysical Research Letters, 50 (15), e2023GL104848.

    Summary from "Aerosols are particles in the atmosphere with sizes ranging from nanometers to tens of micrometers, which are emitted by natural and anthropogenic processes or formed from gases in the atmosphere. The extent to which anthropogenic aerosols affect the radiation budget of Earth is important to better understand anthropogenic climate changes. Aerosol effects on the radiation budget are simulated by complex Earth system models that informed the Sixth Assessment Report of the Intergovernmental Panel on Climate Change. Our study addresses why such model experiments show different magnitudes for aerosol radiative effects. The results point to opportunities to further improve models with existing observations of aerosol optical properties and aerosol transport over oceans in addition to the much-studied aerosol effects on clouds."

    Latif, M., Bayr, T., Kjellsson, J.  Lübbecke, J.F., Martin, T., Nnamchi, H.C.,  Park, W.,  Savita, A., Sun, J. and  Dommenget, D.: Strengthening atmospheric circulation and trade winds slowed tropical Pacific surface warming. Commun Earth Environ 4, 249 (2023).

    Summary: "The globally averaged sea-surface temperature (SST) has steadily increased in the last four decades, consistent with the rising atmospheric greenhouse gas concentrations. Parts of the
    tropical Pacific exhibited less warming than the global average or even cooling, which is not
    captured by state-of-the-art climate models and the reasons are poorly understood. Here we
    show that the last four decades featured a strengthening atmospheric circulation and
    stronger trade winds over the tropical Pacific, which counteracted externally-forced SST
    warming. Climate models do not simulate the trends in the atmospheric circulation irrespective of whether an external forcing is applied or not and model bias is the likely reason."

    Summary: "We assessed the atmospheric dynamics involved in the temporal evolution of the Mongolian cyclone driving the exceptional dust storm in mid-March 2021. The passage of the Mongolian cyclone first induced high dust-emitting winds along its cold front in the Gobi Desert, favouring dust emissions in that region. Subsequently, the Mongolian cyclone caused cold air intrusion into the Taklamakan Desert, promoting the formation of Nocturnal Low-Level Jets (NLLJs) and resulting in subsequent dust emissions in this desert."

    Summary: "Low-level jets (LLJs) typically occur at night due to strong surface cooling. This study provides the first observational evidence that LLJs can also be driven by convectively generated cold pools (CPs), areas of cool and dense air beneath precipitating clouds. CPs can favor temperature inversions with reduced friction of the winds with the surface, as a prerequisite for generating LLJs also during daytime."

    Vidya Varma research Interests are: numerical modelling of climate, impact of anthropogenic aerosols (dust aerosols), radiative forcing and climate
    Feifei Mu research area is: Mongolian cyclones are a precursor to severe dust storms in East Asia. My research aims to systematically clarify the effects of these cyclones on such dust storms, with a specific focus on the dynamic process involved in the outbreaks. I am particularly interested in how Mongolian cyclones contribute to the emissions and transport of dust from various desert regions in East Asia.

    Summary: "The North Tropical Atlantic, through its impacts on the Pacific, is key to tropical climate dynamics and predictability. The drivers of multidecadal changes in the North Tropical Atlantic−Pacific connection are poorly understood. Here it is shown that they are mainly controlled by multidecadal variability associated with the North Atlantic Oscillation."

    Summary: "This thesis separated the effects of stratospheric ozone changes and of increasing concentrations of anthropogenic greenhouse gases on the atmospheric and oceanic dynamics of the Southern Hemisphere. Under the high emission scenario SSP5-8.5, effects of comparable magnitude were found in the stratosphere, while at the surface and in the ocean the greenhouse gas effect dominate. In addition, the thesis investigated the impact of how the ozone field is treated in climate models and found that the effects of changes in stratospheric ozone are weaker when the ozone field is prescribed rather than calculated interactively."
