Base Overview

China Meteorological Administration Lightning and Forest Foreign Science Test Base is located in Conghua District, Guangzhou,jointly constructed and operated by the China Institute of Meteorological Sciences and the Guangdong Provincial Meteorological Bureau。Base to strengthen meteorological service capabilities、Construction of Meteorological Modernization Innovation Platform as the Guidelines,Support my country's lightning monitoring with technology、Lightning early warning forecast、Lightning protection business as a target,Is a lightning and electricity test、Basicity of business and scientific research、Open -type atmospheric electrical comprehensive test base。

Guangzhou Wild Lightning Power Test Base is closely carried out on the needs of lightning power business,Focus on solving key scientific issues facing the lightning business。Base since its establishment in 2006,undertake a number of National Natural Science Fund、973、863 and other major research projects or topics,2006-2014 Published a total of more than 40 papers,Nearly ten patents,Get a number of scientific research results with international influence,Some scientific research results have achieved business conversion,generated significant social benefits。The main results achieved in recent years include:

Bet365 sportsbook review(1) Continuously improve the test conditions of the field venue,Established a domestic first -class thunderbolt field test and test platform。

(2) The development and improvement of artificial triggering lightning technology and measurement technology,As of 2014,Successful triggering Lightning 74 times,Highly accuracy directly measured at the high precision of 10A ~ 10kA current,Get a lot of comprehensive observation information,greatly enrich the accumulation of domestic related data,Data basics are provided for lightning physical and protection research。

(3) Create a close range of the lightning channel、Light、Electric、Magnetic Comprehensive Observation Platform,Realized synchronous observations and acquisitions of multiple measurement systems set in about 17,000 square meters of test fields。

(4) The automatic weather station was launched、Wireless Communication Base Station、High voltage transmission line、Buried Cable、The protective test test of the equipment such as wind turbines and rising protectors in the real lightning environment,Get rich first -hand comprehensive observation information,Research the coupling mechanism and destruction mechanism of lightning electromagnetic pulse (LEMP) in each system,Test the effectiveness and damage mechanism of lightning protection devices,6315_6341。

(5) Based on lightning -based field trials and testing platforms,A quantitative evaluation of the performance of the lightning positioning system,solved the problem that it is difficult to determine the actual operation index of Lightning Positioning Network,It provides an important scientific and technological support for the development of lightning detection technology in my country,It provides an important basis for the application of lightning disaster survey and appraisal and lightning data in disaster weather monitoring and early warning and pattern assimilation。

(6) Create an advanced "Guangzhou High Building Lightning Observation Station",Developed the automatic synchronization observation system of thunderbolt multi -parameter,Get a batch of high -quality observation information,The innovative research results obtained have received high attention and recognition of colleagues at home and abroad。Especially for the first time internationally discovered the side strike behavior of the lightning connection process and the diversity of pilot connection behaviors,Display Bet365 sportsbook reviewthe development feature of the pilot development of high time and space resolution of the lightning connection process,It provides an important observation basis for the development of the guidance mode and the study of lightning protection technology。

In recent years,Guangzhou Wild Lightning Power Test Base Strengthening cooperation with foreign units,If you are with Tsinghua University、Wuhan University、PLA University of Technology、Nanjing Information Engineering University、Hong Kong University of Science and Technology、Cooperation of colleges and universities and research institutions of Guangzhou Institute of Geochemistry, Institute of Earth Chemistry, Chinese Academy of Sciences,Common Research on Wild Test and Test Platform for Totor Electric。other,Some lightning protection、Communication、Petrochemical and other companies are also based on this platform,Test research on related lightning protection technology and facilities was carried out。

Future,Guangzhou Wild Lightning Power Test Base will further accelerate the construction of infrastructure and observation capabilities,Strengthen international and domestic cooperation and exchange,Organize some large lightning comprehensive observation tests,Test capabilities and research fields of expansion bases,Further improve the position of the base in the field of international atmospheric electrical research。

Film All -Sky Cloud Observation System

The Total-Sky Cloud Image, TCI) is the support of the Chinese Institute of Meteorological Sciences,The foundation cloud automation observation equipment independently developed by the State Key Laboratory of the State of the Disaster Weather。Three main components of the TCI device are: camera device、Sun cover device and processing terminal,Among them, the camera device uses a combination of fish eye lens with high stable industrial cameras and perspectives with high stability。Different from other visible light wave segments ground cloud observation equipment,TCI's treatment of the solar obstruction adopts all the light in the spare time、A new type of protection scheme all open during observation,greatly reduced the complexity of the equipment mechanical structure,Suitable for promotion and application。This result has obtained a number of national patent authorization。
