El Niño-Southern Oscillation (ENSO) is a quasiperiodic fluctuation in sea surface temperatures (SSTs) and atmospheric pressure over the equatorial Pacific Ocean, associated with changes in weather in the tropics and beyond. These oscillations typically occur with a periodicity of about 2-7 years.
In this series of Jupyter notebooks, I will show how principal component analysis (PCA), spectral analysis, and other analytical techniques can provide insights into ENSO variability. These notebooks also demonstrate the cartopy package for plotting geographic maps, and the xarray package for handling netcdf
data files and easily stacking / unstacking dimensions to switch between 2-, 3-, and 4-dimensional views of the same array.
