I wanted to check to make sure I was understanding this question correctly.

To get the buoyancy flux I treated this volcanic vent emitting a plume as natural convection determined Grashoff number Nusselt number then found convective heat transfer coefficient. From there I solved for heat flux and then solved buoyancy flux by the eqn B = Q*g*alpha / rho / Cp where alpha is coefficient of thermal expansion rho is air density and Cp is specific heat. Is this all correct? What does the maximum temperature at the 40 m height tell me?

Explanation / Answer

The method which you opted is absolutely right, the maximum temperature at 40m height is very less compared to the temperature at the base of the volcanic vent, the reason for this decrease in temperature is due to hear transfer between volcanic plumes and air flowing through it i.e; by natural convection.
