We are already a month into the new year, and it has been the most exciting times for us here at prepmagic.com. Though for many of us on the east coast, we did see some ugly effects of storm Jonas. Weather has always been a researchers enigma. More we think we know about it, more curve balls it throws at us. For the first time, University of Washington researchers, have convincingly connected the effect of Moon’s tidal forces on the amount of rainfall on Earth. Read more about it here.
So after the updates for January 2016 being live on prepmagic.com, this is what you should expect for the month of February 2016.
