Spin the globe (drag), zoom (wheel / pinch, or the rail on the right), and switch the four weather layers on and off — they stack.
🌡 Temperature — surface temperature painted straight onto the surface, blue → cyan → green → yellow → red, semi-transparent so the continents read through.
🌬 Wind — 10-metre wind as an arrow field. Direction is the arrow's heading; strength shows in arrow size, brightness and colour (pale slate = light, cyan-white = strong).
🌊 Sea currents — the great gyres as flowing teal arrows: Gulf Stream, Kuroshio, Humboldt, Benguela, Canary, Agulhas and the Antarctic Circumpolar Current, plus the equatorial streams. A climatology — always legible, never blank.
⛰ Pressure — the showpiece: mean sea-level pressure pushed into the globe itself. Highs bulge like mountain ranges, lows sink into basins, and relief shading makes the weather systems read as terrain. H/L markers sit on the strongest systems.
· The day/night terminator is real — computed for right now (drag the ☀ bar to move the Sun through 24 h).
· Click any point for a reading: temperature, wind, pressure anomaly, nearest current, and local solar time.
· Live fields come from Open-Meteo (free, no key) on a 10° global grid. If the network is unreachable, the globe falls back to a hand-modelled climatology — Hadley cells, trade winds, westerlies, the subtropical highs and the semi-permanent lows.
