Terrestrial dust devils are known to be triboelectric generators: electric charge is generated and exchanged via the mixing and colliding of moving grains. Static electric fields from the structures have been previously reported, this in excess of 1/2 kV/m at a couple hundred meters from the devil. In this work, we report on AC magnetic measurements made during the passage of an intense ∼10‐m wide, couple hundred‐meter tall dust devil in the Nevada desert. The devil‐related magnetic activity… 

Electric and magnetic signatures of dust devils from the 2000–2001 MATADOR desert tests

[1] Dust devils are significant meteorological phenomena on Mars: They are ubiquitous, continually gardening the Martian surface, and may be the primary atmospheric dustloading mechanism in nonstorm

A model of the ULF magnetic and electric field generated from a dust devil

[1] It has been demonstrated that terrestrial dust devils emit ULF magnetic radiation. On Mars, dust devils may also generate such magnetic emissions, which might be used as a hazard alert for manned

Applications of Electrified Dust and Dust Devil Electrodynamics to Martian Atmospheric Electricity

Atmospheric transport and suspension of dust frequently brings electrification, which may be substantial. Electric fields of 10 kV m−1 to 100 kV m−1 have been observed at the surface beneath

A simple model of the magnetic emission from a dust devil

[1] A simple Rankine-like vortex model of the dust devil behaving as a magnetic solenoid has been constructed. It is augmented with a one-dimensional model describing steady vertical distribution of

Variations of electric field and electric resistivity of air caused by dust motion

We report results of a field campaign conducted in the Nevada desert with a suite of electric field instruments consisting of a field mill (FM) and a short dipole antenna (SDA). Furthermore, we show

Dust devils on Earth and Mars

Dust devils, particle‐loaded vertical convective vortices found on both Earth and Mars, are characterized by high rotating wind speeds, significant electrostatic fields, and reduced pressure and

Extremely Low Frequency Electromagnetic Investigation on Mars

Natural electromagnetic (EM) signals of extremely low frequencies (ELF, 3 Hz–3 kHz) can be used to study many of the electromagnetic processes and properties occurring in the Martian environment.

Modeling the formation of electrostatic discharges on Mars

[1] Mars' low atmospheric pressure and arid, windy climate provide an environment that supports the triboelectric charging of dust. A laboratory experiment has been performed to demonstrate that the

Dust devil dynamics

A self‐consistent hydrodynamic model for the solar heating‐driven onset of a dust devil vortex is derived and analyzed. The toroidal flows and vertical velocity fields are driven by an instability



Detecting electrical activity from Martian dust storms

We present a model addressing the possible electrification of Martian dust storms based on the effective electrical charging of an individual dust grain. An upper charge bound on a grain can be

Electrostatic discharge in Martian dust storms

Although the Martian atmosphere does not satisfy general requirements for lightning generation, there is a possibility of electrical discharge in the case of strong surface winds and a resulting

General Characteristics of Dust Devils.

Abstract An extensive dust devil census taken near Tucson, Ariz., has provided, from two independent areas, quantitative information on the relation of environmental conditions to the spatial

Possible dust devils, vortices on Mars

This paper presents the results of a study of local vortices, and dust devils, on Mars as observed by Viking Landers 1 and 2. It is found that these vortices are most common during Martian spring and

A new SuperDARN meteor wind measurement: Raw time series analysis method and its application to mesopause region dynamics

SuperDARN meteor wind measurements in the mesopause region using the standard analysis of ACFs constructed from the multi‐pulse sequence have several shortcomings. To overcome them, we have developed

Opacity of the Martian atmosphere measured by the Imager for Mars Pathfinder

The Imager for Mars Pathfinder (IMP) has obtained 1733 images of the Sun during its 83-sol mission starting on July 4, 1997, which have been used to determine the atmospheric opacity at wavelengths
