Tropical South America 15s 70w

Creative Rationale

Above the Bolivian Altiplano near the Chilean border, where the thin atmosphere creates extreme pressure variations and temperature anomalies at high altitude. The gentle northeast wind and positive temperature anomaly inspire diagonal squeegee strokes that drag warm underlying colors through cooler surface layers, while the moderate pressure gradient creates multiple revealed paint layers. The high humidity suggests thick, wet paint that blends and bleeds at the edges of each drag mark.
