Thermoelectric effects are more sensitive and promising probes to topologicalproperties of emergent materials, but much less addressed compared to otherphysical properties. Zirconium pentatelluride (ZrTe$_{5}$) has inspired activeinvestigations recently because of its multiple topological nature. We studythe thermoelectric effects of ZrTe$_{5}$ in a magnetic field and find severalanomalous behaviors. The Nernst response has a steplike profile near zero fieldwhen the charge carriers are electrons only, suggesting the anomalous Nernsteffect arising from a nontrivial profile of Berry curvature. Both thethermopower and Nernst signal exhibit exotic peaks in the strong-field quantumlimit. At higher magnetic fields, the Nernst signal has a sign reversal at acritical field where the thermopower approaches to zero. We propose that theseanomalous behaviors can be attributed to the Landau index inversion, which isresulted from the competition of the $\sqrt{B}$ dependence of the Dirac-typeLandau bands and linear-$B$ dependence of the Zeeman energy ($B$ is themagnetic field). Our understanding to the anomalous thermoelectric propertiesin ZrTe$_{5}$ opens a new avenue for exploring Dirac physics in topologicalmaterials.
