The invention relates to a method and a
system for comprehensively and synchronously observing
lightning stroke discharge. The method is based on a
global positioning system (GPS) timing technology, and the
lightning stroke discharge is observed by the
observation system. The method comprises the following steps of: providing the activity trend of
lightning storm by using a
wide area lightning location
system, and reminding the arrival of the lightning
storm by using an atmospheric average
electric field instrument; and outputting an
alternating current (AC) B code
signal to a high-speed image
pickup device by using a GPS timing device, marking the formation time of each frame of picture by using a
clock system, receiving a
time to live (TTL) level
signal from a lightning high-speed trigger device, outputting correct time t corresponding to a TTL level rising edge to a
personal computer (PC), and recording the TTL level
signal and electrical and acoustic measurement signals by using a high-speed data storage recorder. The system comprises the
wide area lightning location system, a
data analysis and
processing server, the atmospheric average
electric field instrument, the high-speed image
pickup device, the lightning high-speed trigger device, a quick
electric field change instrument, a slow electric field change instrument, a
magnetic field measuring instrument, an array
thunder detection device, the high-speed data storage recorder and the GPS timing device.
