sphaericis

Sphaericis, also known as sphaerics or sferics, are a type of electromagnetic phenomenon that occurs naturally in the Earth's atmosphere. They are caused by the sudden discharge of electrical energy, typically from lightning strikes, which creates a spherical wave of electromagnetic radiation. These waves can travel long distances and are often detected by radio receivers as a series of clicks or pops.

Sphaericis are an important area of study in atmospheric science and radio engineering. They can interfere with radio communications, particularly at low frequencies, and are a significant source of noise in radio astronomy. However, they also provide valuable information about the Earth's atmosphere and the processes that occur within it.

The study of sphaericis involves the use of various techniques, including the analysis of radio signals, the measurement of atmospheric electric fields, and the use of satellite-based instruments. Researchers are continually working to improve our understanding of these phenomena and to develop methods for mitigating their effects on radio communications.
