Approximate profile from surface variables + synoptic levels. Red lines = temperature, dashed blue = dew point. Orange bands = detected inversions.
Wind chart — altitude × time
Color: green < 20 km/h · yellow 20-30 · red >40. Arrows point to where the wind is blowing. Each column = 1 hour. 4 altitudes: 10m surface, 80m first thermal, 1500m (850 hPa) thermal cruise, 3000m (700 hPa) top.
