Observations of high-energy radiation during thunderstorms at Tien-Shan

Physical Review D, 2016
Energetic radiation during thunderstorms is studied. The possibility to identify the high-energy lightning emission in the 10 s monitoring mode is demonstrated. Simultaneous measurements of gamma-ray emission, high-energy electrons, and neutron radiation in the triggering mode are fulfilled.

High-resolution full-scale measurements of thunderstorm outflow winds

Journal of Wind Engineering and Industrial Aerodynamics, 2015
Abstract Efforts to understand thunderstorm outflow winds have been ongoing for years in the wind engineering community given the design wind speed for regions away from the hurricane-prone coastline is governed by this phenomenon. These efforts have largely consisted of laboratory and numerical simulations using both impinging jets and thermodynamic-

Discussion of Measurements inside High-Speed Thunderstorm Updrafts

Journal of Applied Meteorology, 1974
Abstract Four soundings taken in high-speed updrafts of severe thunderstorms indicate moist adiabatic ascent to mid-levels. This implies that the cores of strong updrafts are undiluted by environmental air. The Squires-Turner entraining jet model substantiates this conclusion.

The location of thunderstorms by a single-station high-frequency ranging technique

Journal of Atmospheric and Terrestrial Physics, 1956
Abstract By observing the signal radiated by a lightning discharge on a number of frequencies in the high-frequency band, and measuring the maximum usable frequency, the range of the source may be found from a knowledge of the ionospheric conditions. By measuring simultaneously the direction of arrival of the signal, using a low-frequency cathode-ray

Synoptic-Scale Environments Associated with High Plains Severe Thunderstorms

Bulletin of the American Meteorological Society, 1980
Abstract Typical synoptic-scale features are described for summertime severe thunderstorms on the High Plains. Severe weather generally occurs on several days in succession, under conditions that are relatively benign in terms of conventional severe weather parameters.

F-102 HIGH-ALTITUDE FLAMEOUTS IN AND AROUND THUNDERSTORMS

1961
Abstract : It was determined that mixtures of ice crystals and other precipitation commonly found in the core of thunderstorms at high altitudes constitute an extreme operating hazard to F-102 aircraft. The hazard can be relieved to a large extent by the installation and use of a continuous ignition system.

In-flight measurements of high-energy radiation from thunderstorms

2014
Lightning – the bright flashes that put the thunder in thunderstorm – is just one of several mysterious atmospheric phenomena perplexing scientists today. Only recently, scientists learned that thunderstorms sometimes emit bursts of X-ray and gamma-ray radiation.

HIGH LEVEL THUNDERSTORMS OF JULY 31–AUGUST 1, 1959

Monthly Weather Review, 1960
Abstract The high level thunderstorms which occurred in Montana and northern Idaho on July 31 and August 1, 1959 resulted in critical lightning-caused fire conditions. These storms are described and the source of moisture and the instability which initiated them are discussed.

Climate change impact on thunderstorms: Using high-resolution COSMO-CLM simulations to determine changes in thunderstorm occurrences

2018
It is generally assumed that temperature increase associated with global climate change will lead to increased thunderstorm intensity and associated heavy precipitation events. In the present study it is investigated whether the frequency of thunderstorm occurrences will in- or decrease and how the spatial distribution will change for the A1B scenario ...
