The Aonia-Solis-Valles dust storm track in the southern hemisphere of Mars.

ABSTRACT: Dust storm activity in the Aonia-Solis-Valles Marineris (ASV) region is analyzed using data collected from 8 Mars years of Mars Daily Global Maps. During L _s = 120°-180°, dust storms within the ASV region tend to organize into dust storm sequences, making ASV an important storm track in the southern hemisphere outside the conventional dust storm season. In late southern winter, the ASV region is influenced by a combination of strong time-mean winds, synoptic eddies, and tidal winds. The ASV dust storm sequences can increase the background dust opacity and sometimes significantly influence the large-scale atmospheric thermal structure and planetary waves. They can be divided into two groups - one with large size and long duration; the other with small size and mostl
