The 2011 Hurricane Season in 4.5 Minutes

By Vladimir Brezina

Today, November 30, is the last day of this year’s hurricane season.

Hurricanes don’t know that it’s the last day of the season, of course, and in some years they’ve continued well past this date. The hurricane season of 2005, for example, lasted into January 2006; there were so many tropical cyclones that year—among them Katrina and Wilma, respectively the costliest and the most intense Atlantic hurricanes on record—that the prepared names were all used up and six Greek-letter names had to be used.

This year, we are only up to Tropical Storm Sean, so far. This time-lapse satellite-image video compresses the entire 2011 hurricane season into 4.5 minutes. Nothing really striking happens until half-way through the season when the impressive bulk of Hurricane Irene moves up the East Coast of the US… But the time-lapse format does give a powerful impression of the swirling of the weather systems and the recurved paths of the storms—the Coriolis force in action!

  1. What an excellent visual record – time-lapse is a dynamic teaching aid. Irene’s amazing momentum and size was hugely impressive.
