Why in news
Atmospheric scientists captured high-speed video of trees emitting a blue electrical glow (corona discharge) during thunderstorms, potentially impacting understanding of forest impacts on Earth's electrical balance.
Background
The phenomenon is known as corona discharge, occurring when strong electric fields from storms ionize air near tree branches. The resulting faint blue light is distinct from lightning or wildfires and does not cause damage to the trees.
Facts for Prelims
- S&TCorona discharge: A phenomenon where a strong electric field ionizes air to create a faint glow.
- FactThe electrical glow observed in trees is specifically blue in color.
- S&TThe phenomenon is distinct from lightning strikes and wildfires.
For Mains
Q. Discuss how atmospheric phenomena and forest dynamics contribute to the global electrical balance and greenhouse gas composition.
Dimensions to cover in your answer
- Atmospheric interaction: Impact of forest-induced ionization on regional electrical balance
- Carbon cycle link: Potential correlation between electrical discharge and greenhouse gas composition
Keywords: Corona discharge · Atmospheric science · Ionization · Electrical balance · Greenhouse gas composition
