This paper considers the influence of motion of the medium 
(account of convective terms in the heat conduction equations) on 
the photophoresis of a large aerosol spheroidal particle at small 
relative temperature drops in its vicinity. It has been shown that 
at a fixed ratio of semiaxes with increasing intensity of the incident 
radiation the total contribution of the medium motion leads to a monotonic 
decrease in the rate of photophoresis, whose degree depends on the 
equatorial radius of the spheroid.
