Query: Simulation of the 2018 Global Dust Storm on Mars Using the NASA Ames
  Mars GCM: A Multi-Tracer Approach   Global dust storms are the most thermodynamically significant dust events on
Mars. They are produced from the combination of multiple local and regional
lifting events and maintained by positive radiative-dynamic feedbacks. The most
recent of these events, which began in June 2018, was monitored by several
spacecraft in orbit and on the surface, but many questions remain regarding its
onset, expansion and decay. We model the 2018 global dust storm with the NASA
Ames Mars Global Climate Model to better understand the evolution of the storm
and how the general circulation and finite surface dust reservoirs impact it.
The global dust storm is characterized by the rapid eastward transport of dust
in the equatorial regions and subsequent lifting. We highlight the rapid
transfer of dust between western and eastern hemispheres reservoirs, which may
play an important role in the storm development through the replenishment of
surface dust. Both the Hadley cell circulation and the diurnal cycle of
atmospheric heating increase in intensity with increasing dustiness. Large dust
plumes are predicted during the mature stage of the storm, injecting dust up to
80 km. The water ice cloud condensation level migrates to higher altitudes,
leading to the enrichment of water vapor in the upper atmosphere. In our
simulations, the intensity of the Hadley cell is significantly stronger than
that of non-dusty conditions. This feedback is strongly sensitive to the
radiative properties of dust, which depends on the effective size of the lifted
dust distribution.
