OR possibly a circulation issue. Do the top and bottom usually indicate the same temp. and RH?

I thought of batteries but they are only 4-5 months old, and normally I get the same or close to the same readings top to bottom. Now the top has stopped fluctuating and is reading 68 degrees and 62% hum. I think everything is ok inside, I was just wondering about the readings changing.
