Windy Offers Air Sounding Forecast

Air sounding, sounding forecast or skew diagram is here! Yes, there are plenty of names for it. :)

What does it even mean?

Sounding describes a plot of the vertical profile of temperature, dew point and (mostly also) winds above a fixed location. Soundings are used extensively in severe weather forecasting, e.g., to determine instability, locate temperature inversions, measure the strength of the cap (capping inversion), obtain the convective temperature, CAPE (Convective Available Potential Energy), etc.

Horizontal lines represent height in pressure coordinates (millibars or hPa); diagonal lines represent temperature. Heavy solid lines show the vertical profile of observed temperature (red) and dew point (blue). The grey line shows the temperature of a parcel of surface air and how its temperature would change if it was lifted. Source of information: Weather Online.

Where do you find it on Windy and how does it work?
  • Desktop version: Just click with right mouse button anywhere on the map, and use the link in the context menu.
  • Mobile devices: A long tap on display will do!

Here's a quick video tutorial:

This feature was quickly but carefully developed by our zealous pilot & programmer @TZ who hopes you enjoy it!

So far we only support the ecmwf model but other models should follow.

Don't hesitate to give us your feedback!
