thermostat
Perhaps you would like to enlighten me on the difference between red on the wx satellite photo and red on the radar screen, I had no idea there was a difference. To me, red is red and means danger.
Please do your own homework on the subject. (in breif : colors on Wx satellite pictures are based on temperature ; colors on "our" radar displays are based on droplets size. Red on a satellite picture
do not mean "danger", these temperature differences could be shown with any other color).
