Creative Rationale

Over the Sahara-Sahel transition zone at 20°E longitude, where desert meets semi-arid grassland, an intense atmospheric drama unfolds with extremely low pressure and saturated air delivering heavy precipitation to this normally dry region. The gentle easterly wind carries calligraphic marks in flowing horizontal processions across a deep indigo ground, while the unusual moisture and rainfall create veiling atmospheric layers that soften and blur the gestural elements. The cooler temperature anomaly shifts the palette toward cool blues and silver-whites rather than the typical desert warmth, capturing this rare meteorological event as delicate swarming marks that coalesce and disperse like migrating forms across the vast landscape.
