Atmospheric electric field disturbs weather electric field

The disturbing weather electric field is related to the change of meteorological elements. When severe weather phenomena (such as thunderstorm, snowstorm and sandstorm) occur, the value and direction of atmospheric electric field have obvious irregular changes. High clouds have little effect on electric field, while low clouds have obvious effect. The atmospheric electric field under thunderstorm clouds can even reach-104v/m. In stratiform clouds and cumulus clouds, the magnitude and direction of the electric field vary greatly, and the field strength usually appears at about several hundred volts per meter, which is 2 ~ 3 orders of magnitude larger in thunderstorm clouds (see charging in thunderstorm clouds).

Because the change of atmospheric electric field is related to weather, some observatories in the world have accumulated data for many years to seek the law of atmospheric electric field change and its relationship with weather and climate processes.
