Periodic strong winds blowing opposite to the prevailing wind may explain the dune orientation on Titan. On Saturn's moon Titan, giant sand dunes cover more than 20% of the surface. The orientation of thousands of dunes (1, 2) within Titan's equatorial belt indicates transport of sand from west to east (by “westerly” winds), whereas all the atmospheric circulation models suggest that the winds should be in the opposite direction. A new model by Tokano (3) may have found the resolution: Although… 

Implications of dune pattern analysis for Titan’s surface history

Dune-Field Patterns

Temporal variation of the wind environment and its possible causes in the Mu Us Dunefield of Northern China, 1960–2014

Research on the wind environment variation improves our understanding of the process of climate change. This study examines temporal variation of the near-surface wind environment and investigates

Surface modification of silicone tubes by functional carboxyl and amine, but not peroxide groups followed by collagen immobilization improves endothelial cell stability and functionality

Testing of surface-modified silicone tubes containing different functional groups found that silicone-surface modification of blood-contacting parts of artificial lungs with carboxyl and amine, but not peroxide-groups followed by collagen immobilization allows the formation of a stable functional endothelial cell layer.

Dynamique troposphérique et évolution climatique de Titan et de la Terre primitive

Cette these porte sur l'etude des atmospheres de Titan et de la Terre primitive avec des modeles de circulation generale (GCM). Tout d'abord, j'ai analyse la structure thermique et la dynamique de la

Detection and mapping of hydrocarbon deposits on Titan

[1] We report the identification of compounds on Titan's surface by spatially resolved imaging spectroscopy methods through Titan's atmosphere, and set upper limits to other organic compounds. We

An asymmetric distribution of lakes on Titan as a possible consequence of orbital forcing

A set of lakes filled or partially filled with liquid hydrocarbon and empty lake basins have been discovered in the high latitudes of Saturn's moon Titan. These features were mapped by the radar

Multiple origins of linear dunes on Earth and Titan

The formation of dunes is controlled by the direction of the prevailing winds and the characteristics of the sediments. Linear dunes in the Qaidam Basin, China, are shown to form from cohesive

The drying of Titan's dunes: Titan's methane hydrology and its impact on atmospheric circulation

[1] We explore the effect of a finite reservoir of methane on Titan's atmospheric circulation, precipitation patterns, and surface methane content. We develop a soil model that accounts for the

In Dune Map, Titan's Winds Seem to Blow Backward

A new map of the dunes on Saturn9s moon Titan reveals that near-surface winds at the equator blow the wrong way: from west to east.

Global pattern of Titan's dunes: Radar survey from the Cassini prime mission

We present a map of the orientation and extent of Titan's sand dunes derived from the complete radar imaging dataset from the Cassini prime mission. The 16,000 dune segments we have mapped cover ∼8%

Titan's inventory of organic surface materials

Cassini RADAR observations now permit an initial assessment of the inventory of two classes, presumed to be organic, of Titan surface materials: polar lake liquids and equatorial dune sands. Several

The Sand Seas of Titan: Cassini RADAR Observations of Longitudinal Dunes

The most recent Cassini RADAR images of Titan show widespread regions that appear to be seas of longitudinal dunes similar to those seen in the Namib desert on Earth, and the distribution and orientation of the dunes support a model of fluctuating surface winds.
