A Shallow Water Model Exploration of Atmospheric Circulation on Sub-Neptunes: Effects of Radiative Forcing and Rotation Period
Ekaterina Landgren, Alice Nadeau, Nikole Lewis +2
Sub-Neptune type exoplanets are abundant in our galaxy yet have no solar system analogs. They exist in a broad range of stellar forcing and rotational regimes that are distinctly d…
Coupled metronomes on a moving platform with Coulomb friction
Guillermo H. Goldsztein, Lars Q. English, Emma Behta +3
Using a combination of theory, experiment, and simulation, we revisit the dynamics of two coupled metronomes on a moving platform. Our experiments show that the platform's motion i…
A new method of carbon budget analysis with application to present and paleo atmospheric concentration data sets
Alice Nadeau, Richard McGehee, Clarence Lehman
We introduce a new method for analyzing the carbon budget using box models and a mass balance approach. The method describes the net flow of carbon between the atmosphere and other…
Rethinking the Definition of Rate-Induced Tipping
Alanna Hoyer-Leitzel, Alice Nadeau
The current definition of rate-induced tipping is tied to the idea of a pullback attractor limiting in forward and backward time to a stable quasi-static equilibrium. Here we propo…
Synchronous Glacial Cycles in a Nonsmooth Conceptual Climate Model with Asymmetric Hemispheres
Alice Nadeau, James Walsh, Esther Widiasih
We present a new conceptual model of the Earth's glacial-interglacial cycles, one leading to governing equations for which the vector field has a hyperplane of discontinuities. Thi…
Comparison of Two Analytic Energy Balance Models Shows Stable Partial Ice Cover Possible for Any Obliquity
Ekaterina Landgren, Alice Nadeau
In this study, we compare two analytic energy balance models with explicit dependence on obliquity to study the likelihood of different stable ice configurations. We compare the re…
Synchronization of clocks and metronomes:A perturbation analysis based on multiple timescales
Guillermo H Goldsztein, Alice N Nadeau, Steven H Strogatz
In 1665, Huygens observed that two pendulum clocks hanging from the same board became synchronized in antiphase after hundreds of swings. On the other hand, modern experiments with…
Approximating Annual Mean Incoming Solar Radiation
Alice Nadeau, Richard McGehee
We derive the Legendre series expansion for the insolation distribution on rapidly rotating planets as a function of sine of the latitude and the planet's obliquity. We give an exp…
Detecting transient rate-tipping using Steklov averages and Lyapunov vectors
Alanna Hoyer-Leitzel, Alice Nadeau, Andrew Roberts +1
A wide variety of physical systems ranging from the firing of neurons to eutrophication of lakes to the presence of Arctic summer sea ice exhibit a phenomenon known as tipping. In…
A simple formula for a planet's mean annual insolation by latitude
Alice Nadeau, Richard McGehee
In this paper, we use a sixth order Legendre series expansion to approximate the mean annual insolation by latitude of a planet with obliquity angle , leading to faster computat…
