Code and data for the stochastic skeleton model of the Madden-Julian oscilation with time-dependent observation-based forcing

The Madden-Julian oscillation (MJO) is a planetary-scale wave envelope of smaller-scale convective processes, slowly propagating eastward at the equator, going around the Earth in 30 to 60 days. The convection and circulation anomalies associated with the MJO affect weather and climate in many parts of the globe. This set of files contain a Julia implementation of the MJO skeleton model, a minimal nonlinear oscillator model of thie MJO. Previous studies primarily relied on mathematically simple and time-independent forcings in this model. Here, observation-based, time-dependent forcing functions are used to capture more realistic variability. The code presented here reads-in the needed reanalysis data, runs the skeleton model on them, and produces figures from the output data.
