NASA Helps Highlight Lightning Safety Awareness Week

22.06.2005


Summertime arrives officially on June 21 in the northern hemisphere, and with it comes thunderstorms. As a result, the National Oceanic and Atmospheric Administration named the week of June 19-25 National Lightning Safety Awareness Week.



NASA encourages summer swimmers, picnickers and others to keep an eye on the sky and stay safe during outdoor activities. NASA lightning expert Dr. Dennis Boccippio, of NASA’s Marshall Space Flight Center (MSFC) in Huntsville, Ala., warns that lightning safety should never be taken lightly. An average of 67 people are killed by lightning each year, and thousands of dollars’ worth of property is damaged or destroyed, according to the National Weather Service.

Boccippio and the NASA lightning team study this powerful natural force year-round, using equipment on Earth and in space, to learn how lightning and severe weather interconnect, and to determine new ways to protect lives, homes and property.


NASA researchers at have created lightning maps that show where and how much lightning strikes worldwide. The maps are color coded to indicate concentrations of lightning strikes. Each frame represents average lightning activity on each day of the year. This data, compiled from space-based sensors, show how lightning strikes are not evenly distributed around the world. This data is not only important to meteorologists, but to climatologists, as well. Lightning indicates the location of large storms that release latent heat; the "fuel supply," that helps drive the Earth’s climate "engine."

The National Weather Service’s regional forecast offices in Alabama have been using NASA’s North Alabama Lightning Mapping Array since November 2001. The data help characterize thunderstorm initiation, identify weakening and strengthening storms by the change in the rate of flashes, and evaluate the trend of the flash rate to improve severe storm detection and lead-time. Understanding lightning could help improve severe storm warning lead-time by up to 50 percent and decrease the false alarm rate for non-tornado producing storms.

NASA’s lightning research is also being applied to aviation safety. NASA technology is helping aviators avoid turbulence over offshore areas, by using surface lightning measurements and combining them with satellite lightning data and other measurements.

"Knowing the precise location of lighting helps with aviation safety, and helps forecasters locate the most intense regions inside thunderstorms," said Dr. Jeffrey Halverson, Tropical Rainfall Measuring Mission Outreach scientist and meteorologist at NASA’s Goddard Space Flight Center, Greenbelt, Md.

Im Focus: Temperature-controlled fiber-optic light source with liquid core

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.

Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Im Focus: AchemAsia 2019 will take place in Shanghai

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
