We give an improved derivation of the solutions to the covariant Wigner function for chiral fermions in background electromagnetic fields to the first order in the Planck constant. We use the thermal distribution function under static-equilibrium conditions including the Killing condition for $\beta^{\mu}=u^{\mu}/T$ with $u^{\mu}$ and $T$ being the fluid velocity and temperature respectively. The results reproduce our previous ones except that the vorticity is replaced by the thermal vorticity. The chiral vortical effect (CVE) current is derived from the first order solution in the same way as in previous works with explicit Lorentz covariance. In the semiclassical expansion without assuming the thermal distribution function and static-equilibrium conditions, there is a freedom to choose a reference frame in which the time-component of the Wigner function is defined. So the explicit Lorentz covariance seems to be lost. Once the thermal distribution function under static-equilibrium conditions is used, the CVE current can be decomposed into two parts, the normal and and magnetization part, each of which depends on the reference frame. However it can be shown that the sum of the two does give the total CVE current which is reference frame independent.
