India Wind Forecast Map

What's on the Map

• Wind 10m — surface wind, the standard meteorological reporting height.
• Wind 100m — hub-height wind for utility-scale wind turbines (see also Renewable Energy Forecast).
• Wind 850 hPa — roughly 1,500 m, the low-level jet and monsoon flow level.
• Wind 500 hPa — roughly 5,500 m, mid-tropospheric steering flow.
• Wind 300 hPa and Wind 200 hPa — upper troposphere, where the subtropical and polar jet streams are strongest.
• Barbs at every level above, for a static direction/speed readout instead of the animation.

Questions This Page Answers

• Will surface winds or gusts be strong enough to affect boating, high-sided vehicles, hoardings or outdoor work?
• Where is the monsoon's low-level jet feeding moisture onto the west coast?
• Where is the jet stream at cruise altitude, and how strong is it?

How to Read It

• Pick the level for the question: 10 m for everyday surface conditions, 100 m for wind turbines, 850 hPa (about 1.5 km) for monsoon flow, 500 hPa (about 5.5 km) for what steers weather systems, and 300–200 hPa for jet streams.
• Reading barbs: the staff points into the wind; each half barb is 5 knots, each full barb 10 knots and each filled pennant 50 knots (1 knot ≈ 1.85 km/h).
• Gusts do the damage. Mean wind understates peak loads — check the Wind Gust layer for anything structural, marine or aviation-related.
• Seasonal signatures: in the southwest monsoon, a strong 850 hPa westerly over the Arabian Sea is the low-level jet and strong 200 hPa easterlies over south India are the Tropical Easterly Jet; in winter, the westerly subtropical jet sits over north India at 200 hPa.

Who Uses This

Multi-level wind maps support flight planning at cruise altitude (see the Aviation Dashboard for turbulence and jet stream charts), wind farm site assessment and short-range generation forecasting (see Renewable Energy Forecast), and tracking synoptic-scale steering flow for monsoon systems and cyclones.
