NCAR's George Bryan explains how the weather balloon team probes conditions near fast-moving storms and tornadoes during VORTEX2. Rawindsondes, or sondes, are small instrument packages that take "soundings," or measurements of temperature, moisture, and other key data as the balloon ascends. And then there's the challenge of coordinating the balloon teams on the largest tornado study in history. VORTEX2 is the Verification of the Origins and Rotation of Tornadoes Experiment.
