      I remember that there was once the variable "equivalent potential temperature" - a very important one for meteorologists!

      It is a common variable found in the models as "theta_e" - since I am now Premium Subscriber, I would really love to see it back in the list!

      Short explanation (source wikipedia):
      " θ e {\displaystyle \theta _{e}} \theta _{e} is the temperature a parcel of air would reach if all the water vapor in the parcel were to condense, releasing its latent heat, and the parcel was brought adiabatically to a standard reference pressure, usually 1000 hPa (1000 mbar) which is roughly equal to atmospheric pressure at sea level. "

      Which makes it such a nice variable to look at, because fronts are easy to detect in 850hPa and the amount of water can be derived with it as well.

        Yes, thêta e and even more interesting thêta’w are 2 very important potential temperatures used in meteo. The goal of Windy is to be an outdoor application oriented, not really to be a tool for meteorologists, although we have tonrecognize that a lot of them use Windy because the app is very nice and easy to use!

        Having said that, we can debate about the limit : when data are outdoor oriented and when data are really dedicated for meteorologists only ?

        I would love to see thêta’w at 850hPa in Windy as it is something I use extremely often and I have to go to another site ton get the info,... But it is maybe not enough outdoor oriented

        One idea could be to integrate thêta’w in the sounding or in a SkewT type (emagram) of plugin

          Please integrate the equivalent potential temperature in windy. This map shows the isobars together with the isolines of the equivalent potential temperature in 850 hPa. The equivalent potential temperature is made up of the temperature and humidity at 850 hPa. This is why weather fronts (strong displacement of the equivalent potential temperature) and different air masses can be seen even more clearly here than on the 700 hPa humidity map or the 850 hPa geopotential map.
