1. Analysis of the Stommel Model to Understand Abrupt Change within the Earth SystemGreyson Dunn
2. MethodTime step of a year. Iterate for 1000 years to simulate timescale of ocean circulation. Solve systems of ODE numerically using 4th order Runge-Kutta method.Note: I preferred convention to switch S1 and S2
3. Base CaseSystem in a steady state. Equilibrium reached within timescale of ocean’s circulation despite flux of salt from atmosphere.
4. Younger Dryas ForcingInsert a forcing(Increase in magnitude of H in high latitudes). This can be from trigger mechanism such as a meteorite->warming/melt. System becomes unstable and enters runaway feedback unstable. Conveyor turns off.
5. What does this mean for the future with current climate change? Questions?
