A few weeks ago, I posted an article about vertical atmospheric mixing. The article focused on a single day (Oct. 10, 2016) in Portland, ME. In the article, I looked at both the variability of winds during a 24-hour period (day versus night) and also examined atmospheric soundings. Today, I’d

A category 5 hurricane is one with sustained winds of 157 miles per hour (137 knots) or more. At 8:00 a.m. E.D.T., on Oct. 1, 2016, Matthew’s winds were estimated to be just
