Image properties:

  • flat PNG images - 1280 x 850 px (1 - 1,5 MB)
  • animation GIF images - 1280 x 850 px (~ 3,5 MB)

Features

  • Multiple pressure layers (1000/700/550/350 hPa)
  • Equivalent potential temperatures (shaded)
  • Vectors of theta-e advection - vector magnitude equals to length of "advection" vector |gradHTe| . |w||, direction parallel to wind flow, red color for "warm" advection, blue for "cold" advection
  • Contours of theta-e 6-hour tendency (dashed lines for negative tendency)
  • Significant wind vectors (1000 hPa .. ws > 6 m/s, 700 - 350 hPa .. ws > 10 m/s)
  • Animations
  • 72-hour weather prediction
  • Updated every 12/24 hours
