Distinguishing between insolation-driven and phase-locked 100-kyr ice age scenarios using example models
Published in Paleoceanography and Paleoclimatology, 2024
This study examines two proposed mechanisms underlying the ~100-kyr glacial cycles of the Pleistocene:
(1) insolation-driven glacial terminations, and
(2) phase-locking between internal ice-sheet oscillators and orbital forcing.

Comparing the surface mass balance of the Laurentide Ice Sheet during the last deglaciation with geophysical reconstructions
Published in , 2025
We investigate the evolution of the Laurentide Ice Sheet (LIS) during the last deglaciation by calculating its surface mass balance (SMB) using the isotope-enabled transient climate model experiment iTraCE. Two melt-rate frameworks are developed and compared, including a new parameterization of the refreezing of snowmelt and liquid precipitation, along with statistical downscaling of model output.
Can ENSO–QBO correlations arise mechanistically? Insights from simple dynamical models
Published in , 2025
Building on our observational and CMIP6 analysis, this companion paper explores whether ENSO–QBO correlations can be generated through well-defined physical mechanisms. We use a wave-driven simple model and investigate the impact of wave amplitude modulation from seasonality and ENSO effects.
ENSO–QBO interactions in observations and CMIP6 models: signal, noise, and the limits of short records
Published in , 2025
This study examines the robustness of the observed ENSO–QBO relationship using reanalysis products and CMIP6 preindustrial control simulations. We evaluate whether the commonly reported correlation between ENSO amplitude and QBO phase represents a true dynamical coupling or arises from sampling variability given the short observational record (~40 years)
What controlled the growth and retreat of the Laurentide Ice Sheet? A comparison of the 80 ka glacial growth and the 12 ka deglaciation
Published in , 2025
This study investigates the distinct climate factors that can switch the surface mass balance of the Laurentide Ice Sheet from positive (growth phase) to negative (decay phase). Given two stages of the glacial cycle with the same ice volume, what causes one ice volume to grow and the other to decay?
