Viewing and monitoring lightning
In this activity, students view a short video on lightning phenomena and then answer a set of questions based on the video. They will then log on to WWLLN (which stands for the world wide lightning location network) and view recent lightning activity in the South Pacific region around New Zealand.
How WWLLN began
University of Otago’s space physics expert Associate Professor Craig Rodger describes how the lightning detection network known as WWLLN began.
By the end of this activity, students should be able to:
describe in simple terms how an atmospheric cloud-to-ground lightning discharge occurs
explain the meaning of the terms ‘stepped leader', 'streamer’ and ‘sferic'
give a brief outline of the operation of WWLLN (the world wide lightning location network)
demonstrate familiarity with safety suggestions for people exposed to thunderstorms.
What is WWLLN?
Associate Professor Craig Rodger from the Space Physics group at the University of Otago describes his involvement in the setting up and running of the World Wide Lightning Location Network (WWLLN).
