3D radar.

One cell, the area around it, or the whole scan out to 140 miles, standing over the map. Orbit, pan, and pinch down into a single core.

A wide three-dimensional radar box over New Jersey and the coast, with a long line of storms standing in it.

One storm cell in three dimensions, seen from low down: a tall column of reflectivity with a magenta core inside it.

Radar velocity in three dimensions over St. Louis: air moving toward the radar in green and away from it in red, standing as solids above the map.

Velocity in 3D, too. A rotation couplet is a shape inside the storm.

The wind in 3D.

Every level from the surface to the jet stream, moving at its real height. Or lay the wind flat across the radar map.

Live Level II radar.

Reflectivity, velocity, spectrum width and dual-pol, from the station as each scan arrives.

BeamWeather's flat radar view around St. Louis: storms in greens, yellows, reds and magentas over a map with range rings, and the date and scan time on the timeline.

Storm cells.

Every cell in the scan, strongest first, with peak intensity, echo top and VIL.

A vertical cross-section through a storm, height against distance, with the radar beam paths drawn as diverging lines and the space between them left empty.

Cross-sections.

A vertical slice through the storm. Where no beam reached stays empty.
