The systems we developed and are now utilizing, incorporate a weather station that transmits digital data. The station computer processes eight sensor inputs in real time for access back to the mainframe computer in the Emergency Management Center. We have developed software that analyzes each stream of data from these sensors for status change. The channels dedicated to process Atmospheric Pressure, sensor resolution is in thousands of an inch. Processing starts when a fluctuation as little as 2 millibars an hour is detected.
Wind velocity is processed at two levels to alarm to burst wind signatures.
This enables the computer to determine rotation from straight line wind force levels.
