Diffuse afternoon water-ice clouds continued to be the prominent feature over the tropics of Mars this past week. Among these latitudes, local-scale dust storms were observed over eastern Meridiani, southern Arabia, and northeast of Arsia Mons (the southernmost volcano of … Continue reading →

During the past week on Mars, dust hazes and dust clouds were observed over northern Utopia, just west of the Olympia dune field. Looking to the low latitudes, the aphelion cloud belt proceeded to dominate the skies with condensate water-ice … Continue reading →

Northern Hemisphere Summer Solstice arrived last week on Mars. The northern polar ice cap had nearly reached its perennial (near minimum) configuration. Dust lifting off of the northern cap edge contributed to dust hazes over Acidalia and northern Utopia. The … Continue reading →

Dust-lifting near the north polar ice cap led to murky conditions over parts of Acidalia and northern Utopia. The dust that was pushed southward over Acidalia, formed a stationary dust cloud — likely the result of an eddy. Looking to … Continue reading →

Last week on Mars, a slight up-tick in dust-lifting occurred along the north polar ice cap edge. As storm activity northeast of Tempe pushed dust southward over the plains of Acidalia, a dust storm also swept over the sands of … Continue reading →

This past week dust-lifting near the edge of the perennial north polar ice cap transported dust to the plains of Arcadia and Acidalia. Meanwhile, an expanse of water-ice clouds, known as the aphelion cloud-belt continued to dominate the skies of … Continue reading →

Dust-lifting activity near the north polar ice cap swept diffuse dust clouds southward to the plains of Acidalia this past week. Looking further south, short-lived local-scale dust storms were spotted northwest of Elysium Mons. In the mid-latitudes, water-ice orographic clouds … Continue reading →

The dominant weather feature last week was the aphelion equatorial condensate (water-ice) cloud belt. Predominately a northern hemisphere feature, it does extend a distance into the southern tropics. In addition, orographic condensate clouds were observed over all the major shield … Continue reading →

Dust-lifting activity was sparse this past week on Mars. In the first half of the week, small dust storm fronts and hazes were spotted over northern Acidalia — near the seasonal north polar ice cap edge. Looking further south, equatorial … Continue reading →

Weather conditions were relatively unchanged from last week. Tiny transient dust storms were spotted northwest of Elysium Mons and southwest of Syrtis near the middle of the week. During that time, frontal dust storms streamed off the seasonal cap over … Continue reading →
