On the section about tornadoes he called 4 dots in the south and southeast flukes! How can I trust his teachings when he has no knowledge, yet well known everywhere, about Dixxie Alley? Southern Mississippi and central Alabama actually have cities that get hit by more tornadoes than I tornado alley annually. Plus the south produces more EF4-5's than tornado alley. Dixxie alley kicks up earlier than tornado alley and runs longer. From Dec - April. This is very well known data not some fluke and there is lots of data on it. Suggest starting with NOAA or NWS. Hard to believe that Yale in 2011 has no clue about southern tornadoes. Especially after the largest outbreak in years in April 2011 killing over 300 people. Once again not a fluke happens every year. Deleting this from iPhone since I can not trust being taught good and factual information from a professor who lacks the knowledge any high schooler with an interest in weather knows
