H-representing high surface pressure, L-representing low surface pressure. If we could bisect a hurricane, conditions on the inside would look something like this: (known as the organized convection theory) Extending outward from the eye we encounter rain bands which “spiral” outward from the center, and can reach hundreds of miles beyond the eye. The eye wall is where the strongest winds and heaviest precipitation is found. Surrounding the eye is the eye wall, which forms a cylindrical barrier of intense thunderstorms and cloud cover reaching altitudes of nearly 49,000 ft above sea level. The eye is the area of broken clouds and relatively calm conditions, located in the center of this low pressure system. (Ahrens, 2003) A hurricanes anatomy is relatively simple, made up of three major parts: the eye, eye wall, and spiral rain bands.Ī simplified hurricane cross section showing the eye, eye wall, rain bands, and relative motion within the Northern Hemisphere. So what does all of that mean? By definition in the Northern Hemisphere, a hurricane is an intense storm of tropical origin, with sustained winds exceeding 74 mph (64 knots), and forms over the warm northern Atlantic and eastern North Pacific Oceans. Today, as of 11:00 am (EDT) Mathew has downgraded to a Tropical Depression, with winds of 75 mph, a surface pressure of 984 millibars, and is located 100 miles east of Cape Hatteras, North Carolina. Wind gusts have been reported as high as 76 mph, with a surface pressure of 962 millibars. Hurricane force winds extended 45 miles from the center of Mathew, with tropical-storm-force winds extending nearly 185 miles from the center. 8 at 8:00 am (EDT), Mathew was located ~20 miles (35 km) south-southeast of Charleston, SC. For those of you who don’t live on the east coast and maybe aren’t following Mathew closely, here’s an update: as of Oct.
Sadly, not everyone made it through safely as nearly 900 people were killed in Haiti and 17 here in the US. (NASA, 2016)Īs Hurricane Mathew made headlines and moved slowly from the northern coast of Venezuala along the east coast of the United States, many people witnessed the extreme forces brought about by Hurricane Mathew. Hurricane Mathew, located just off shore of South Carolina as of Oct.
