In shortAn open AI weather model produced a seven-day outlook for East China on a single cloud GPU in about half an hour. Research charts, not a forecast service.
The FuXi model (Fudan University) run through NVIDIA Earth-2 / earth2studio: GFS 0.25° initial state, initialised 2026-03-29 00UTC, 7 days / 168 hours, six variable groups over East China (105–130°E, 22–45°N). A single research case, not a forecast service.
Pick a day and all six charts follow; click any chart to enlarge.
500 hPa sits near 5.5 km and is the core level for the large-scale flow. Tighter contours mean stronger wind; the blue side is colder (troughs), the red-orange side warmer (ridges). Black contours are sea-level pressure, marking surface highs and lows. Across the seven days you can watch troughs and ridges travel west to east.
850 hPa, about 1.5 km up, is the main lane for low-level jets and moisture transport. Deeper warm colours mean stronger wind; broad strong-wind bands usually mark a low-level jet. Barbs show direction; where southerly and northerly flows meet is often where fronts and rain sit.
700 hPa, about 3 km up, is the most direct level for rain potential: green moist areas tend to match where it rains, brown dry areas the fair-weather zones. Follow the green across seven days and you are following the rain band.
The chart closest to how the day feels: black isobars mark highs and lows, cool colours are colder, warm colours warmer. The boundary between air masses — the front — swings north and south over time, which is why East China’s spring weather changes so often.
Wind at 10 m, directly comparable with station observations and the base quantity for offshore work, shipping and wind-energy assessment. In the Northern Hemisphere air converges anticlockwise around lows and diverges clockwise around highs; compare with 850 hPa to read vertical wind shear.
Daily 24-hour accumulated precipitation (mm); lighter to darker means weaker to heavier. Read it with 700 hPa humidity and 850 hPa wind to see where the rain band comes from and where it goes.
