Antarctic Vortex Thermal Profiler

Ice peak landscape with severe blowing snow whiteout

Polar Boundary Telemetry

The Antarctic Vortex Profiler integrates ground radiosondes, automated weather stations (AWS), and polar-orbiting satellite radiometers to deliver live tracking of extreme cold air outbreaks and katabatic wind surges down the Antarctic plateau.

Extreme Metrics Tracked

  • Katabatic Wind Velocity Acceleration: Gravity-driven cold dense air funneling through coastal glaciers at speeds reaching up to 200 knots.
  • Whiteout Visibility Index: Combining ambient luminance, surface contrast, and suspended ice crystal density to warn research teams of total optical orientation loss.
  • Stratospheric Warming Oscillations: Monitoring sudden stratospheric warming (SSW) events that destabilize polar vortex boundaries.

Field Operations Impact

Operating in environments where ambient temperatures drop below -60°C (-76°F) requires heated anemometers and specialized power systems. Field teams utilize this profiling suite to schedule safe flight windows and ice-traverse logistics.
