WHAT DO SUNSPOTS HAVE TO DO WITH HURRICANES?

SUNSPOT CYCLES

Frankly, I don’t think anyone really knows. We do know that the energy that activates much of our weather comes from solar radiation. Sunspot numbers have been tallied for a little over 400 years. We have seen the Sunspot Maximums numbers decrease since the year 2000; in fact, the 2013 peak of sunspots is the least number since the year 1906.
Yearly averaged numbers of sunspots 1610-2010

It has been commonly believed that the only relation of the number of sunspots to the earth’s weather has been the Maunder Minimum when there were little or no sunspots observed between 1645 and 1715. That was the time when most of the northern hemisphere experienced a cooling that has been called the Little Ice Age. It was not a true ice age and some think there may have been other factors, such as volcanic activity and changes in ocean circulation that may have played a part.

When it comes to the number of hurricanes, during the period centuries prior to the year 1900 hurricane, totals were mainly tallied from ship logs, diaries and storm damage that was sometimes reported from mainly more populated locations. With our twenty first century technologies and communications we will be able to learn much more of the true cause and effect of the sun on our hurricanes and climate.

One fact stands out about global warming. Since the end of the last Ice Age about 18,000 years ago, the oceans have risen more than 300 feet. This is not entirely from glacial melt, but also from the expansion of water with warmer temperatures. Continental drift since then has been another factor.

It’s no wonder that the computer models of tropical storm DORIAN do not portray identical tracks 7 days from now. Stay tuned to our team of meteorologists on Channel 4 and the latest from the National Hurricane Center, and when a storm approaches be sure to heed the advice of your Local Emergency Preparedness Center.

    I was raised watching George Winterling and I am 60 years old. I trust him. His name is like being one of the family. I found the information on the sun spots and hurricanes , was very interesting.

      Thank you for your comment. I am watching for our global warming to slow down or reverse with our hurricane seasons becoming less active.
