Longitudinal Dependance Of Solsticial Hadley Cell Detected At The Edge Of The Massive Martian Erg

TL;DR

This study uses high-resolution images to analyze wind patterns on Mars, revealing seasonal and local variations in the Hadley cell influenced by geological features, enhancing understanding of Martian atmospheric dynamics.

Contribution

It introduces a novel method of deriving wind directions from high-resolution images to study Martian atmospheric behavior at high latitudes.

Findings

Dunes indicate dominant northern summer winds.

Localized SE winds suggest perturbation of the Hadley cell.

Wind patterns are influenced by geological depressions.

Abstract

Using public HIRISE images of MARS, I derive the wind directions at high Northern lattitudes, where many interesting eolian features are observed. BArchan dunes show prominent wind direction from the North indicating that they formed during the southern summer. But a few record consistent SE winds near the UTOPIA PLANITIA basin. The wind reversal is consistent with a local perturbation of the solsticial Hadley cell caused by geological depression.
