A network of antennae are connected to a central processor that records the time, polarity, signal strength, and number of strokes of each cloud-to-ground lightning flash detected over the United States. CC BY-NC-ND 3.0Įxcept where otherwise noted, images are subject to copyright. National Lightning Detection Network (NLDN) is a commercial lightning detection network operated by Vaisala. (2023), Scientists can now map lightning in 3D, Eos, 104. Then, divide the number of seconds by three and you have figured out the distance to the thunderstorm in kilometers: Example: 12 seconds pass between lightning and thunder 12 seconds divided by 3 equals 4 that means the thunderstorm is 4 kilometers away. Morgan Rehnberg ( Science Writer Citation: Rehnberg, M. Just count the seconds between the lightning and the thunder. ( Journal of Geophysical Research: Atmospheres,, 2023) These novel capabilities, the authors say, expand the horizon of what’s possible in the study of lightning physics. Radar and lightning data for the past 24 hours can be displayed. New images are available every 15 minutes. They even demonstrated that for events with linear polarization, BIMAP-3D can deduce the orientation of the radio polarization in three dimensions. The map shows precipitation intensity from weather radars in Sweden, Norway, Finland and Denmark and lightning from lightning sensors. There is hardly any weather phenomenon that excites us. They computed 3D maps showing the shape and development of each lightning event, including both cloud-to-cloud and cloud-to-ground events. Lightning strike map get live information about current thunderstorms through lightning detection. The team then applied their new instrumentation and analysis techniques to several observed lightning strikes. What’s more, they could track the development of lightning within fractions of a microsecond. Under favorable conditions, the researchers could pinpoint a lightning strike’s source location to within several meters at an altitude of kilometers aboveground. They can integrate these two analyses for accurate triangulation. The authors describe two techniques for triangulating the path of a lightning strike by combining data from the two stations: one based on geometry and the other based on time of arrival. By using both stations simultaneously, scientists can map lightning and detect polarization in three dimensions. These stations, which are separated by 11.5 kilometers, each consist of four sets of broadband and polarized antennas arranged in a Y shape. Left-clicking on the 'Speed' area will slow the loop and right-clicking will accelerate the loop, ranging from 0.05 to 5 second interval. Their second-generation BIMAP-3D (Broadband Interferometric Mapping and Polarization in 3D) system utilizes two observation stations. Clicking on the map will start/stop the loop. Adding a third dimension could resolve these long-standing problems in lightning physics. extended radio-frequency interferometry and polarization detection to three dimensions. That limitation prevents scientists from answering fundamental questions, such as where and how lightning starts in a cloud and how quickly different discharge processes occur. Gray = Expired Alert - It's unclear if it's safe to return, or if the authority has just not updated it quickly enough.Still, this method can only localize a lightning strike and detect its polarization in two dimensions.
