What some differences between northeast and southeast and why

The southern coastline tends to get hurricanes more frequently than the northern coastline. The southern coastline is closer to the equator, where ocean water absorbs high levels of energy from the Sun. As the water from the Gulf Stream moves northward, the water cools, which decreases the risk of strong hurricanes hitting land. Also, if a hurricane strikes the southern coastline, its energy drops off before it can travel north.
