| Abstract: | This paper describes a method for identifying martian dust devils and convective vortices in meteorological data. We have combined analysis of terrestrial dust devil fieldwork, re-analysis of martian meteorological data and laboratory experiments to explore fully the meteorological signature of dust devils. Both martian and terrestrial dust devils have similar characteristics implying a common formation mechanism. Terrestrial fieldwork therefore provides vital data that can be used to aid in the identification of their martian counterparts. Finally, a martian surface instrument package is suggested that will best detect dust devils and convective vortices without the need for visual confirmation. |
