Average solar p-mode eigenfrequencies are decreased by large fluctuating velocity fields in the upper convection zone. This effect is greatest for modes with large horizontal wave numbers and frequencies. It is large enough to affect estimates of the depth of the convection zone and may carry useful information about the structure of solar convective turbulence.
