Abstract
A severe storm warning system includes an atmospheric pressure sensor utilizing an air-filled chamber with a first pressure sensor mounted between the interior of the chamber and the atmosphere and being located within the chamber interior and a second pressure sensor mounted between the interior of the chamber and the atmosphere and being located outside the chamber. Both sensors are formed of multiple-plate, floating plate capacitors which are movable in response to pressure changes. Electronic circuitry periodically determines what pressure changes have occurred and compares the changes to the changes associated with a predetermined signature of the type of severe storm being determined. Indicators including alarms are provided if a known sequence of pressure changes is detected.
