Typhoon Science


Scott: Officials are still looking at whether or not Haiyan was the largest storm to ever hit land, with nearly 200-mile-per-hour winds. And to get a feeling of its size, check out these pictures.

This is what the once thriving city of Tacloban looked like before. And this is what it looks like now after being hit by Typhoon Haiyan. But to get a feel of its size, check this out: a satellite view as Haiyan approached the Philippines, a chain of 7,000 islands. If the same storm hit the East Coast of the United States, it would cover an area from Florida to New England.

So just how did this storm get so big? Typhoons feed off warm air and water, and the ocean temperatures were a steamy 86-degrees. And because the warm air was out in deep ocean water, there was no land around to disrupt it from forming a circular pattern. There was also very little wind shear. That is when wind comes in at different speeds and different directions. And, in this case, the wind was mostly heading in the same direction, so the storm kept its strong circular pattern.
