The function calculates convection from an organism to its environment as in Mitchell (1976) . It includes an enhancement factor associated with outdoor environments.
Qconvection(T_a, T_b, A, proportion, H_L = 10.45, ef = 1.23)numeric air temperature (K).
numeric initial body temperature (K).
numeric surface area (m2).
numeric proportion of surface area exposed to air.
numeric convective heat transfer coefficient (W K-1 m-2).
numeric is the enhancement factor, used to adjust H to field conditions. Approximated as mean value of 1.23 by default, but see Mitchell (1976)
for further information.
numeric convection (W).
