Abstract
Regional dust storms develop in the Southern Hemisphere (SH) of Mars typically three times in years that do not experience a Global Dust Storm. The Thermal Emission Spectrometer and the Mars Climate Sounder instruments on board Mars Global Surveyor and Mars Reconnaissance Orbiter, respectively, have observed that the storms that generally appear in the and time periods, commonly referred to as A- and C-season regional dust storms, respectively, are preceded by atmospheric dust ‘flushed’ into the SH from the Northern Hemisphere (NH) mid-latitude storm track through one of the vast lowland channels, most frequently via Acidalia–Chryse or Utopia–Isidis. Here, reanalysis data are used to analyze the typical behavior of transient and tidal waves before and after cross-equator flushing storms that trigger regional storms, revealing the characteristic atmospheric wave evolution surrounding these events. In particular, the analysis shows that a strong wavenumber 3 transient wave and a mid-latitude tide amplification typically precede flushing events. Furthermore, our results suggest that while Acidalia-related regional storms typically require multiple high-amplitude wave events, regional storms initiated through Isidis may happen more abruptly.
期刊介绍:
Icarus is devoted to the publication of original contributions in the field of Solar System studies. Manuscripts reporting the results of new research - observational, experimental, or theoretical - concerning the astronomy, geology, meteorology, physics, chemistry, biology, and other scientific aspects of our Solar System or extrasolar systems are welcome. The journal generally does not publish papers devoted exclusively to the Sun, the Earth, celestial mechanics, meteoritics, or astrophysics. Icarus does not publish papers that provide "improved" versions of Bode''s law, or other numerical relations, without a sound physical basis. Icarus does not publish meeting announcements or general notices. Reviews, historical papers, and manuscripts describing spacecraft instrumentation may be considered, but only with prior approval of the editor. An entire issue of the journal is occasionally devoted to a single subject, usually arising from a conference on the same topic. The language of publication is English. American or British usage is accepted, but not a mixture of these.
