docs: def plot_dry_adiabats(self, p=None, theta=None, **kwargs):
          r'''Plot dry adiabats.
  
          Adds dry adiabats (lines of constant potential temperature) to the
          plot. The default style of these lines is dashed red lines with an
          alpha value of 0.5. These can be overridden using keyword arguments.
  
          Parameters
          ----------
          p : array_like, optional
              1-dimensional array of pressure values to be included in the dry
              adiabats. If not specified, they will be linearly distributed
              across the current plotted pressure range.
          theta : array_like, optional
              1-dimensional array of potential temperature values for dry
              adiabats. By default these will be generated based on the current
              temperature limits.
          kwargs
              Other keyword arguments to pass to
              `matplotlib.collections.LineCollection`
