DOI: 10.1002/2017gl073658
Abstract: Numerical models run in non-rotating Radiative-Convective Equilibrium (RCE) using prescribed sea surface temperatures (SSTs) show that convection can spontaneously aggregate into dry and moist areas, and that convective aggregation tends to increase with temperature. Using… read more here.

DOI: 10.1029/2023ef003734
Abstract: Arctic warming has significant environmental and social impacts. Arctic long‐term warming trend is modulated by decadal‐to‐multidecadal variations. Improved understanding of how different external forcings and internal variability affect Arctic surface air temperature (SAT) is crucial… read more here.

DOI: 10.1073/pnas.2209431119
Abstract: Significance Comparisons between climate models and satellite observations consistently find that simulated warming of the tropical troposphere outpaces observations after 1979. There are a number of factors that may contribute to this discrepancy. Using machine… read more here.
