Initial stage in lightning initiated from tall objects and in rocket- triggered lightning
[1] We examine the characteristics of the initial stage (IS) in object-initiated lightning derived from current measurements on the Gaisberg tower (100 m, Austria), the Peissenberg tower (160 m, Germany), and the Fukui chimney (200 m, Japan) and their counterparts in rocket-triggered lightning in Florida. All lightning events analyzed here effectively transported negative charge to ground. For ...
متن کاملX-ray Observations at Gaisberg Tower
We report the occurrence of X-rays at ground level due to cloud-to-ground flashes of upward-initiated lightning from Gaisberg Tower, in Austria, which is located at an altitude of 1300 m. This is the first observation of X-ray emissions from upward lightning from a tower top located at high altitude. Measurements were carried out using scintillation detectors installed close to the tower top in...
متن کاملDetailed Brightness versus Ligthning Current Amplitude Correlation of Flashes to the Gaisberg Tower
In 1999 a digital high speed video camera was installed at the lightning experimental site at the Gaisberg tower. The camera is capable of capturing black and white images in speeds of up to 1.000 frames/s. The camera is triggered by a trigger signal derived from the lightning current measured at the tower top. In summer 2000 five flashes were recorded by the digital camera and for those five f...
متن کاملNO signatures from lightning flashes
In situ measurements of cloud properties, NO, and other trace gases were made in active thunderstorms by two research aircraft. Concurrent measurements from a three-dimensional (3-D) VHF interferometer and the 2-D National Lightning Detection Network were used to determine lightning frequency and location. The CHILL Doppler radar and the NOAA-WP-3D Orion X band Dopper radar were also used to me...
متن کاملCharacterization of Pulses Superimposed on the Initial Continuous Current of Upward Lightning
We compare the characteristics of initial continuous current pulses (ICC pulses) in natural upward lightning as observed on the Gaisberg tower (100 m), the Peissenberg tower (160 m), and the Fukui chimney (200 m) with their counterparts in rocket-triggered lightning in Florida. All lightning events analyzed here effectively transported negative charge to ground. The geometric mean (GM) values o...
