Creative Rationale

Over the equatorial Atlantic, northeast of the Windward Islands where the trade winds carry moisture across warm tropical waters, the atmospheric conditions create a luminous, humid environment with moderate winds and stable pressure. The high humidity of 82% calls for deeply translucent color washes that layer and overlap like watercolor on wet paper, while the warm temperature anomaly suggests golden ochres and salmon pinks bleeding outward across the canvas. The moderate wind from the northeast creates diagonal flows of color staining across the composition, with the pressure gradient causing subtle tilts in how these ethereal fields pool and spread.
