Next-Generation Satellite Dissects Storms From Top To Bottom

Meteorologists are getting a whole new view of the weather systems that bring rain, snow and ice thanks to an instrument launched into orbit earlier this year. The next-generation Global Precipitation Measurement satellite and a constellation of other observatories and relays scan the entire globe every three hours to send back an avalanche of data.

Tiny Drones Deliver Bird’s-Eye View Of Hurricanes

When a major storm develops, we want to know where it will hit and how strong it will be. Currently, the best way to study a hurricane is to fly a plane near the storm to collect data. But, that approach can be costly, not to mention very dangerous.

“If you look at Katrina, we were completely wrong with the intensity of the hurricane” said Kamran Mohseni, an aerospace engineer at the University of Florida in Gainesville.

To track storms now, aircraft fly over the storms and drop a device that collects data as it falls through the clouds. But it’s not a perfect way to collect information.

“You put people at risk. The airplane is at risk and it is extremely expensive, and if you crash, that’s major news,” said Mohseni.

Exceeding the 140-Character Limit: Twitter Leaves the Twitter-Sphere

image

by Ysabel Yates

On January 15, 2009, an airplane carrying 150 passengers collided with a flock of birds just 15 minutes after leaving New York City’s LaGuardia Airport. The quick-thinking pilot landed the plane in the Hudson River and became a hero when every passenger survived. The flight made history that day, but something else did, too: a rapidly expanding social media platform called Twitter.

That day, a rescue worker on the ground tweeted about the incident and took the now-iconic photograph of the plane in the water. In a recent CNBC documentary, “The Twitter Revolution,” Jack Dorsey, Twitter’s co-founder, said that for him, this was the moment when the platform revealed itself to be more than just a 140-character status update.

“It just changed everything,” he said. “Suddenly the world turned its attention, because we were the source of news—and it wasn’t us, it was this person in the boat, using the service, which was even more amazing.”

Forecasting When Volcanoes Will Erupt

by Marsha Lewis, Inside Science TV

There are 15,000 active volcanoes around the world. Of those, about 50 erupt each year, spewing steam, ash, toxic gases and lava. But scientists don’t know which volcanoes are most likely to erupt. A new tool is helping them to figure that out.

More than 43,000 people live in the shadow of Mauna Loa in Hawaii, the largest volcano on Earth.  Another 80,000 people live in the danger zone of Mount Rainier in Washington state.
