- Example, Electric Dipole and Atmospheric
- Sprites:
- We can model the electric field due to the charges in the clouds and the ground
- by assuming a vertical electric dipole that has charge -q at cloud height h and charge +q at below-ground depth h (Fig. 22-9c). If q =200 C and h =6.0 km, what is the magnitude of the dipole’s electric field at altitude z1 =30 km somewhat above the clouds and altitude z2 =60 km somewhat above the stratosphere?
- Sprites (Fig. 22-9a) are huge flashes that occur far above a large thunderstorm. They are still not well understood but are believed to be produced when especially powerful lightning occurs between the ground and storm clouds, particularly when the lightning transfers a huge amount of negative charge -q from the ground to the base of the clouds (Fig. 22-9b).
