External boundary layer convection

## Information

The external boundary layer convection requires a slightly more complex model than the internal convection, since air circulation around the dome removes hot air from the surface, thereby seemingly enhancing the convecting area.

The model is essentially the same model as used for internal convection, but the conductance of convection is here not a constant, but rather a function of the wind velocity.

The wind velocity is retrieved from a large lookup table.

    Parameters:

      ac:    Cover area of Biosphere (default value = 5667.0 m2)

      hai:   Convection coefficient equation intercept (default value = 39.6 kJ/(h.m2.K))

      hai2:  Convection coefficient equation slope (default value = 0.0034 kJ/(m3.K))

      ucx:   Cover normal specific thermal conductance adjustment factor (default value = 1)

      ucp:   Cover normal specific thermal conductance (default value = 72 kJ/(h.m2.K))

      R2:    Specific resistance due to conduction (default value = 1/(ucx*ucp) h.m2.K/kJ)
