Aerological diagram or Skew-T Log-P diagram for cloudiness forecast for Murmansk, Russia

The diagram is built from aerological sounding data using a radiosonde or weather model data. In the Windy.app, we are using data from the ICON13 weather model. The forecast depth is seven days.

Reading this chart could be a little complicated, but when you practice a bit, this will be like a walk in a park to you.

In this diagram, there are three curves on the chart:

  • The red one depicts the air temperature at different altitudes.
  • The green one depicts dew points at different hights.
  • The blue one depicts the behavior of air volume that rises from the surface.

For example, the closer the green curve is to the red one, the higher the humidity and the greater the probability of cloudiness and precipitation are. And vice-versa.

Learn more about aerological diagram is and how to read it correctly in the Windy.app blog or tapping on the “i” sign at the top right corner of the diagram screen.

At the moment, the function is only available in the Android version.
