![]() Seek shelter if lightning is observed or thunder is heard.When lightning is detected in your area, please adhere to all lightning safety guidelines presented by the National Weather Service. The HLMA can advise when lightning activity may occur in a particular area. The data should never be used as a means for lightning protection. Publicly available HLMA data are posted every minute. Lightning data can be requested by contacting Dr. ![]() The link to the HLMA website is available here. Hence, deep convective clouds that develop over the Gulf of Mexico can be examined by the magnitude of lightning activity. Using lightning to illustrate the rapid intensification (RI) and rapid weakening (RW) of tropical cyclones presents the opportunity for the HLMA network to examine the total lightning structure within tropical cyclones that impact the Texas coast. The primary research goals of the network are to (a) investigate the charge structure of total lightning within thunderstorms as they develop, (b) examine the relationship between electrical activity within deep and shallow convection from continental and tropical systems with respect to precipitation rates, and (c) examine any potential impacts of lightning on urban, coastal, and marine environment and infrastructure. The VHF source data are grouped into 80 and 400 μs bins which are used for scientific analysis and real-time data web image display. The sensors utilize a time-of-arrival calculation method which provides 3D lightning information around the Houston Metropolitan area and 2D information to surrounding regions within a 250 km radius of the HLMA network center (which includes the Gulf of Mexico). It is a surface-based network of twelve sensors which monitor VHF radiation source events from lightning on a locally unused TV channel (e.g., Ch.

Interesting: Lightning | Lightning strike | Automated airport weather station | Convective storm detection Image i - Lightning detector at the Kennedy Space Center in Florida. Space-based lightning detectors, on artificial satellites, can locate range, bearing and intensities by direct observation. Ground-based systems use triangulation from multiple locations to determine distance, while mobile systems estimate distance using signal frequency and attenuation. Ground-based and mobile detectors calculate the direction and severity of lightning from the current location using radio direction-finding techniques together with an analysis of the characteristic frequencies emitted by lightning. ![]() It also was the first radio receiver in the world. The device was invented in 1894 by Alexander Stepanovich Popov. There are three primary types of detectors: ground-based systems using multiple antennas, mobile systems using a direction and a sense antenna in the same location (often aboard an aircraft), and space-based systems.
