Rain radar

Five minutes at a time.

A new composite from the national radar networks every five minutes, rendered to the pixel the moment it lands. Scroll to move through the last two hours.

Then two hours ahead.

The loop does not stop at now. A physics-based nowcast carries every shower forward, so you see where the rain is heading, not only where it has been.

One map, many radars.

Germany's DWD composite stitched with the networks of Switzerland, France, Czechia and Poland. Borders are for maps, not for weather.

Storm tracking

Every cell, found for you.

Convective cells are detected in each composite and given a code, a severity, a peak reflectivity and an echo top. No squinting at colours.

Followed from birth to decay.

Cells are matched from scan to scan into tracks. Splits and merges are kept as a family tree, so a storm's history travels with it.

And told where it is going.

Motion vectors become a forecast: where each cell will be in fifteen, thirty, sixty minutes. Tap your place and read off when it arrives.

The storm sheet

Everything a cell knows about itself.

Open any cell and get its readings, its history, its family and a 3D model of its structure, straight from the radar volumes.

The meteocool map with a storm cell opened: its readings, 3D structure, history and family
Readings Peak, echo top, VIL, gusts, lightning rate
Structure The cell's volume, drag to turn
History Reflectivity and echo top over the track
Family Parents and children from splits and merges

Storms in 3D

Tilt the sky.

The radar does not only scan the ground. meteocool rebuilds the full volume from every sweep and lets you fly around it, cut it open and read a slice at any altitude.

Turn the storm. The storm sheet's structure model is the cell's measured shells, stacked by height. Drag it round as you would in the app, straight from the storm sheet.
Slice it at any height. CAPPI, the radar meteorologist's horizontal cut: everything above a height cut away. The slice sweeps by itself; drag up or down to hold it.

The storm on this page was real.

Every frame, track and reading above was captured from meteocool's demo replay of the German Bight convection. The live map has today's weather.
