All I found on this was that there were barely a record 25 tropical cyclones in the northern hemisphere in 2015 directly linkedto El Niño. This record 25 seems to follow a pattern every 10-13 years where levels are increased to about 20. I traced this back to the late 1800's. These tropical cyclones are hardly cat 4-5 hurricanes as the wind speeds are routinely under 113km/hr. I got my info from noaa. The hurricane season generally follows the same pattern but lately less hurricanes have been making landfall. There wasn't a major one to make landfall in 12 years. I don't think you could explain anything sophisticated as you have your bias which leans to man made climate change as an absolute fact. If that is so show me in a mathematical way the numbers that man contributed to climate change which has and will continue long after man is long gone. I know it can't be done but I'd love to hear you try and explain it as you're so sophisticated and continually point out others lack of.
