Saturn’s moon Titan has a dense nitrogen-rich atmosphere, with methane as its primary volatile. Titan’s atmosphere experiences an active chemistry that produces a haze of organic aerosols that settle to the surface and a dynamic climate in which hydrocarbons are cycled between clouds, rain and seas. Titan displays particularly energetic meteorology at equinox in equatorial regions, including sporadic and large methane storms. In 2009 and 2010, near Titan’s northern spring equinox, the Cassini… 
Dust Devils on Titan
Conditions on Saturn's moon Titan suggest that dust devils, which are convective, dust‐laden plumes, may be active. Although the exact nature of dust on Titan is unclear, previous observations
Intermittent saltation drives Mars-like aeolian activity on Titan
Titan, the largest moon of Saturn, is characterized by gigantic linear dunes and an active dust cycle. Much like on Earth, these and other aeolian processes are caused by the wind-driven mobilization
Titan’s Prevailing Circulation Might Drive Highly Intermittent, Yet Significant Sediment Transport
Titan, the largest moon of Saturn, is characterized by gigantic linear dunes and an active dust cycle. Much like on Earth, these aeolian processes are caused by the wind‐driven saltation of surface
A Global Geomorphologic Map of Saturn’s Moon Titan
TLDR
The results show that Titan’s surface is dominated by sedimentary or depositional processes with a clear latitudinal variation, with dunes at the equator, plains at mid-latitudes and labyrinth terrains and lakes at the poles.
Dune Formation and Sand Transportation on Titan
Nearly 20% of Titan’s surface is covered with equatorial linear dunes similar to sand dunes on Earth. However, the sand on Titan is not made of silicates, as on Earth, but mainly of organic materials

Tracking Short-term Variations in the Haze Distribution of Titan’s Atmosphere with SINFONI VLT
While it has long been known that Titan’s haze and atmosphere are dynamic on seasonal timescales, recent results have revealed that they also exhibit significant subseasonal variations. Here, we
The Role of Seasonal Sediment Transport and Sintering in Shaping Titan's Landscapes: A Hypothesis
Titan is a sedimentary world, with lakes, rivers, canyons, fans, dissected plateaux, and sand dunes. Sediments on Saturn's moon are thought to largely consist of mechanically weak organic grains,
The lifetime of charged dust in the atmosphere
Windblown dust plays critical roles in numerous geophysical and biological systems, yet current models fail to explain the transport of coarse-mode particles (¿5 µ m) to great distances from their

The Climate of Titan
Over the past decade, the Cassini-Huygens mission to the Saturn system has revolutionized our understanding of Titan and its climate. Veiled in a thick organic haze, Titan's visible appearance belies
Storms in the tropics of Titan
TLDR
These observations show that convective pulses at one latitude can trigger short-term convection at other latitudes, even those not generally considered capable of supporting convection, and may also explain the presence of methane-carved rivers and channels near the Huygens landing site.
Seasonal changes in Titan's meteorology
The Cassini Imaging Science Subsystem has observed Titan for ∼1/4 Titan year, and we report here the first evidence of seasonal shifts in preferred locations of tropospheric methane clouds.
CHARACTERIZATION OF CLOUDS IN TITAN'S TROPICAL ATMOSPHERE
Images of Titan's clouds, possible over the past 10 years, indicate primarily discrete convective methane clouds near the south and north poles and an immense stratiform cloud, likely composed of
Rapid and Extensive Surface Changes Near Titan’s Equator: Evidence of April Showers
TLDR
The detection by Cassini's Imaging Science Subsystem of a large low-latitude cloud system early in Titan’s northern spring and extensive surface changes in the wake of this storm are reported, which suggests that the dry channels observed at Titan's low latitudes are carved by seasonal precipitation.
Global circulation as the main source of cloud activity on Titan
TLDR
The global spatial cloud coverage on Titan is in general agreement with the models, confirming that cloud activity is mainly controlled by the global circulation, and suggests that Titan's equator-to-pole thermal contrast is overestimated in the models and that its atmosphere responds to the seasonal forcing with a greater inertia than expected.
TRAMS: A new dynamic cloud model for Titan's methane clouds
Convective clouds on Titan may play an important role in climate dynamics, atmospheric chemistry, and the overall volatile cycle. To study the formation and evolution of these clouds, we have

Cassini's Imaging Science Subsystem (ISS) has been observing Titan since April 2004, compiling a nearly global surface map and monitoring the surface and atmosphere for activity. Early images of the
