So, as an amateur , I ask :
Why this?:
http://www.predictweather.com/articles.asp?ID=16"Each Moon phase has a changing effect on the weather, whether it be droughts, hurricanes, tornadoes or lightning. And as the atmosphere has its daily tide, the air density too is forever changing. If it did not, barometric pressures would always remain constant. The volume of air changes just as does the volume of sea water in a bay during high SEA tide, but we can see that. We can't see a high AIR tide because we haven't yet invented an instrument to detect it. Yet by deduction we can conclude that it must occur. To put it another way, it would be very odd if the Moon chose to move the sea around but decided against moving the massive sea of air."
It seems reasonable to me...
