Sahara Sahel

Creative rationale

Over the Sahara-Sahel transition zone at the intersection of the Prime Meridian and Equator, this atmospheric reading captures a moment of unusual moisture and warmth in one of Earth's most arid regions. The gentle wind speed of 1.9 m/s translates into slow, wide undulations that breathe across the canvas, while the moderate pressure gradient creates evenly spaced line intervals that maintain Riley's characteristic precision. The significant temperature anomaly and high humidity drive a shift from her typical desert-inspired black-and-white patterns toward a restrained color progression of warm coral through pink to deep burgundy, reflecting the unexpected atmospheric moisture in this transition zone.
