The wind and VHF radar reflectivity fields around frontal zones are examined. While even weak upper level baroclinic zones can be seen in both the reflectivity and wind fields, the reflectivity signature of low level fronts may be obscured. Humidity terms dominate the refractive index gradient in the lower troposphere and can mask the enhancement of the gradient as a result of the stable frontal layers.
