Going Inside the Tornado With LabVIEW and NI CompactDAQ

Tuesday, January 24, 2012

While most people take cover when a tornado strikes, meteorological scientists from TWISTEX chase after them to capture ground-level data to help researchers better understand and predict atmospheric conditions.  So when it came time for TWISTEX to develop a sturdy, stand-alone instrument that could collect, store, and visualize large data sets, they turned to NI products and LabVIEW to help them out.




The TWISTEX team used NI CompactDAQ hardware, LabVIEW, NI DIAdem, and an NI 3110 industrial controller to obtain, process, and display the sound, temperature, air pressure, wind speed, and direction from the bottom 2 m of the tornado. Using NI products, TWISTEX created an instrument that can measure audio from inside a tornado funnel, a first for meteorological scientists everywhere.
