Weather station
ActiveUS7171308B2Special data processing applicationsAtmospheric potential difference measurementLightning strikeThunderstorm
A weather station for providing weather information to a user, especially weather information related to lightning and severe thunderstorm activity. In accordance with the present invention, the weather station includes one or more antennas for receiving GPS transmissions, weather radio transmissions, and a separate radio band, such as the AM radio band for use in detecting lightning strikes. The GPS signal is used to determine the position of the user. A lightning detector coupled to the antenna for receiving the AM (or other band) signal calculates the proximity of any detected lightning strikes. The national weather radio band antenna receives information from NOAA and similar organizations and presents it to the user in the normal fashion. In accordance with the present invention, the weather station may take storm data from NOAA and compare it to lightning proximity data that it has already obtained at a particular location and present to the user an indication of the relative location of the severe thunderstorm activity and its direction of movement.
