    When looking at charts that show isotherms (or adiabats/quasi-adiabats) at 850hPa, 500hPa and so on, to what kind of temperature are they referring?

    1) Temperature

    2) Virtual Temperature

    3) Potential Temperature

    4) Potential Wet Bulb Temperature

    5) Equivalent Potential Temperature

    ???

    I always see it referred to as simply "temperature", but I don't know if this is abuse of definitions or not.

    Thanks

    :)

    The 850, 700, 500mb charts which show isotherms are showing the actual air temperture or forecast actual air temperature - as would be measured by a thermometer attached to a weather balloon (radiosonde).

    But beware models calculate other 'temperatures' which are useful in forecasting.
