By some measures, today is the day on which a named tropical storm is most likely to occur. Does that make it the peak of hurricane season? According to a recent blog post by Brian McNoldy, a Senior Research Associate at University of Miami’s Rosenstiel School of Marine and Atmospheric Science, it’s not quite so simple. You can measure by when storms occur or by the accumulation of energy, and you can use different datasets depending on how much you trust the counts before we had satellites that could see the “fish” storms that never made landfall. I think you will find this to be a very enlightening discussion. I highly recommend following his blog for many excellent posts about hurricane climatology and upcoming storms.
