I'm certainly no meteorologist! It seems we've had more foggy mornings this summer than in years past. Humidity has certainly been high with only a handful of stretches with more than a day below 50% relative humidity. Many times it seems as though warm air over cooler moist ground is necessary for its formation. I don't think this is a temperature inversion, as such, but they also seem to sometimes be quite localized and are related to some interesting effects. I along with other radio amateurs and possibly Greg find the effects of these weather phenomena on VHF and UHF radio propagation interesting. - Nate -- "The optimist proclaims that we live in the best of all possible worlds.
