Question
I am a reporter with The Dallas Morning News. I am based in Cuba and filed a story today on Cubans' sudden ability to view dozens of American TV programs on their television sets. I'm told this is due to the weather conditions. For tomorrow's newspaper, I want to try to explain to our readers how it works. I am wondering if you can help. Thank you. Tracey
P.S. You can view my story at www.dallasnews.com

Answer
Hi Tracey

Sometimes temperature inversions can act as a high television antenna to propagate tv signals abnormally long distances.
