This repository contains the Python scripts and generated interactive Plotly figures to visualize the 3D structure of Sudden Stratospheric Warming (SSW) events.
Background:
These figures were originally generated as part of my BSc thesis: Impact of the Stratospheric Polar Vortex on Temperature and Precipitation in the Northern
Hemisphere Climate. Supervisor: Cristina Peña-Ortiz.
The included script (3d_SSWvortex_plev_ght_anom_1yr.py) processes ERA5 daily geopotential data to construct a 3D animated timeline of the Geopotential Height Anomalies. The event onset (Day 0) is classified automatically by identifying at least 10 consecutive days where the zonal wind at 10hPa (60°N) is negative (u < 0).
You can view the interactive timeline directly via GitHub Pages:

Data
Plotted events were calculated using the geopotential average from 2000 to 2024.
