The windscreens are all bonded so no rubber seal involved, has the car had a replacement windscreen that you know of? If so it may be a poor bond in that area.
Also bear in mind the climate control may be directing outside air into the car at this time of the year so direction flaps may be in different positions increasing the airflow noise through the vents and pipework,try turning the climate control completely off and see if the noise goes with it.
