Good evening, fellow bloggers. It’s about time I got another post out! Since we’re just about to wrap up the Atlantic hurricane season, I figured that I should post something pertaining to tropical systems. Although tropical system develop elsewhere around the world, I will focus on tropical systems in the Atlantic Ocean and the Gulf of Mexico.
First of all, for those unsure on what the “Atlantic hurricane season” is, According to the National Hurricane Center page “Tropical Cyclone Climatology”, it’s a time period (from June 1st to November 30th) where conditions are usually favorable for the development of tropical systems. Yes, it is still possible for tropical systems to form outside of that time frame. Most of these “non-season” storms form in May, but there are also a few throughout history that have formed in December.
The peak of the Atlantic Hurricane Season is early September, followed by a smaller peak in mid-October. The most common tracks and points of development differ depending on the atmospheric conditions and portions of the season. Any coastal region is at risk for tropical system impact, although some locations are more prone than others. The Outer Banks of North Carolina and the southern tip of Florida have experienced higher tropical system return periods. However, the rest of Florida and the Gulf coast are not far behind with their return periods. Additional information about these topics can also be found on the National Hurricane Center’s Tropical Cyclone Climatology page.
After all of this overview, I wish to discuss the very quiet Atlantic hurricane season that occurred this year. The main culprit for the quiet hurricane season was the persistence of dry air over peak developmental areas, as shown in a graphic posted by the Capital Weather Gang in late September. With the lack of warm, moist air in peak developmental areas, tropical disturbances that actually developed quickly dissipated. While the 2013 season persists until the end of the month, it is safe to say that this year’s tropical development in the Atlantic will be below average. In conclusion, those who love the beauty and power of tropical systems had minimal satisfaction this season. However, those who live in high-risk areas (and their insurance companies) savored the hiatus.
