Observation of Anomalous Propagation of Radio Waves in the MW Band

However, several times I observed the anomalous propagation in the summer time. It was at the morning at Super Moon, meteor showers or at sharp changing of the atmospheric pressure. As usual I observed the abnormal propagation at morning time before sunrise. In the period from December to January, anomalous propagation is also observed in the evening, after 4 pm, when I am driving home, it is time before and after sunset.

Spot of the anomalous propagation

Spots where I observed the anomalous propagation are located in constant places. On my way to work I have observed three spots at the QUEEN ELIZABETH WAY highway and four spots in Buffalo. What is interesting, in Buffalo there are churches near all of the four spots. However, there are lots churches in Buffalo and may be it is not related to anomalous propagation of the MW Band...

On the QUEEN ELIZABETH WAY highway, two spots of the anomalous propagation are located on bridges and in places at a distance of 200-300 meters from these bridges. These ones are the Welland River Bridge and the Niagara River Bridge (Peace Bridge).

Peace Bridge located one side in Canada and other side in the USA. Peace Bridge is the place where the QUEEN ELIZABETH WAY highway ended.

One spot on QUEEN ELIZABETH WAY highway is a really interesting spot. The temperature there (I measured the temperature by my car thermometer) is usually lower to 1-3 degrees than the temperature before and after the spot. The lower the temperature in the spot is (compare to before and after the spot) the better the reception of the far radio stations at frequencies of 630 and 670-kHz are and Radio WTVN Radio does more jamming to Radio CKTB Radio . The spot is located near exit 25, exit to Netherby Road.

I have no explanation for the anomalous reception on the MW Band. Especially I have no explanation for the great improvement in radio propagation in in certain permanent spots. I just listen to the radio in my car and share my experience with you. However, this confirms the presence of spots where the anomalous radio reception exists.
