Electric and Magnetic Fields from Return Stroke-Lateral Corona System and Red Sprites

Electric and Magnetic Fields

California Electric and Magnetic Fields Program A Project of the California Department of Health Services and the Public Health Institute INTRODUCTION Our daily use of electricity is taken for granted, yet scientific and public concern has arisen about possible health effects from electric and magnetic fields (EMF) that are created by the use of electricity. Because of this concern, the Califor...

Lightning Electric and Magnetic Fields

Characteristics of measured electric and magnetic fields generated by various lightning processes are reviewed. Ground flashes of both polarities and cloud flashes are considered. Examples of different types of field waveforms are given.

Charge moment change and lightning-driven electric fields associated with negative sprites and halos

[1] Sprites are structured high altitude optical emissions produced by lightning-driven electric fields. Both strong positive and negative cloud to ground flashes (CGs) are capable of initiating sprites. However, reported sprites are almost exclusively produced by +CGs. The very limited number of negative polarity sprites makes it difficult to reveal their morphologies and mechanisms. Since 200...

Magnetic Braiding and Parallel Electric Fields

The braiding of the solar coronal magnetic field via photospheric motions – with subsequent relaxation and magnetic reconnection – is one of the most widely debated ideas of solar physics. We readdress the theory in the light of developments in three-dimensional magnetic reconnection theory. It is known that the integrated parallel electric field along field lines is the key quantity determinin...
