A Close Encounter with a Terrestrial Dust Devil
نویسندگان
چکیده
Introduction: During August 03 a dust devil field investigation campaign was conducted in the El Dorado Valley, Nevada. This field site has been well characterised previously [9], and has a well documented record of dust devil events. We report on one particular encounter from this field campaign, whereby a dust devil was sampled by a large number of sensors. These measurements consist of wind speed at 8 heights up to 4m, wind direction at 5 heights, air temperature at 6 heights, air pressure at 2 heights, upward looking UV flux (opacity) and 2 dust impact sensors. As such this data set represents one of the best characterisations of a dust devil lower structure to date. Dust flux estimates obtained can be compared to those expected on Mars. Figure 1

Quasi-electrostatic field analysis and simulation of Martian and terrestrial dust devils
[1] Recent experimental and modeling studies show that large quasi-static electric fields (2–20 kV/m) can be developed in a Martian or terrestrial dust devil as a result of contact electrification and charge separation of dust grains with different sizes and compositions. Electric discharging occurs when the maximum electric field reaches breakdown values ( 20 kV/m on Mars and 3 MV/m on Earth, ...
متن کاملUsing an Instrumented Drone to Probe Dust Devils on Oregon's Alvord Desert
Dust devils are low-pressure, small (many to tens of meters) convective vortices powered by surface heating and rendered visible by lofted dust. Dust devils occur ubiquitously on Mars, where they may dominate the supply of atmospheric dust, and since dust contributes significantly to Mars’ atmospheric heat budget, dust devils probably play an important role in its climate. The dust-lifting capa...
متن کاملA Multiyear Dust Devil Vortex Survey Using an Automated Search of Pressure Time Series
Dust devils occur in arid climates on the Earth and ubiquitously on Mars, where they likely dominate the supply of atmospheric dust and influence climate. Martian dust devils have been studied with a combination of orbiting and landed spacecraft, while most studies of terrestrial dust devils have involved manned monitoring of field sites, which can be costly both in time and personnel. As an al...
متن کاملThe Open University ’ s repository of research publications and other research outputs Diurnal Variation in Martian Dust Devil Activity
We show that the dust devil parameterisation in use in most Mars Global Circulation Models (MGCMs) results in an unexpectedly high level of dust devil activity during morning hours. Prior expectations of the diurnal variation of Martian dust devils are based mainly upon the observed behaviour of terrestrial dust devils: i.e. that the majority occur during the afternoon. We instead find that lar...
