Hurricane Sandy's devastation

Still in awe of the size and power of Hurricane Sandy? The PBS program "Nova" will soon delve into just how such a storm occurred.

Though it hasn't even been a month since the storm devastated much of the Northeast, an episode titled "Inside the Megastorm" will air twice in the coming days -- Nov. 18 and Nov. 21, at 9 p.m. both nights.

Here is the program description:

Was Hurricane Sandy a freak combination of weather systems? Or are hurricanes increasing in intensity due to a warming climate? How did this perfect storm make search and rescue so dangerous? "Inside the Megastorm" takes viewers moment by moment through Hurricane Sandy, its impacts, and the future of storm protection. Through first person accounts from those who survived, and from experts and scientists, "Inside the Megastorm" gives scientific context to a new breed of storms.

Weather watchers have been trying to break down the why behind Sandy's freak-of-nature characteristics since even before it struck. The Weather Underground's Jeff Masters delves into it in a must-read blog post from earlier this week.

As Masters explains: "At its peak size, twenty hours before landfall, Sandy had tropical storm-force winds that covered an area nearly one-fifth the area of the contiguous United States." Only Tropical Storm Olga in 2001 has had such a wide footprint of tropical storm force winds, and no hurricane has compared.
