Land-Sea Thermal Contrast & Monsoon Onset — 2D Seasonal Dial

2D energy-balance dashboard: a polar seasonal clock, a scrolling land/sea/ΔT strip chart and a 2D wind-reversal schematic all driven by the same land-sea heat-capacity ODE that governs real monsoon onset. Drag the clock to scrub the year.

Monsoon onset is, at its core, a heat-capacity story: land is a thin slab that heats and cools quickly under seasonal sunlight, while the ocean's mixed layer behaves like a deep reservoir that lags far behind. This 2D edition runs the same energy-balance ODE as the 3D version, but visualizes it as a scientific dashboard: a draggable polar seasonal clock tracing the solar forcing cycle, a scrolling strip chart of land/sea/ΔT temperatures against the onset threshold, and a 2D wind-reversal schematic that flips from a dry offshore breeze to a moisture-carrying onshore flow the instant ΔT crosses +4 °C.

⚙ Under the hood

A 2D energy-balance dashboard: a draggable polar seasonal clock traces the solar forcing cycle, a scrolling strip chart plots land, sea and ΔT temperatures against the monsoon onset threshold, and a 2D cross-section schematic flips the near-surface wind direction the instant ΔT crosses the threshold — the same land-sea heat-capacity ODE as the 3D version, visualized natively in 2D.
