New World Record for Super Typhoon Haiyan: a 180-Ton Boulder Transported

On November 8, 2013, the world changed forever for the people of the Central Philippines. The strongest tropical cyclone at landfall on record in world history, Super Typhoon Haiyan, crashed ashore on the island of Samar, bringing a massive storm surge of 15 - 23 feet to the city of Tacloban. At least 6,300 people died, mostly due to the storm surge, making it the deadliest typhoon in modern Philippines history. Storm surge surveys published earlier this year revealed that high waves on top of the surge created high water marks of up to 46 feet above mean sea level—among the highest in world history. New research presented by Max Engel and co-authors from the University of Cologne in Germany at this week’s American Geophysical Union meeting in San Francisco, California found that Haiyan’s surge set another all-time record: the heaviest boulder known to be moved by a tropical cyclone. The team’s post-storm survey found a number of multi-ton boulders transported by the storm, with the heaviest being an incredible 180 metric tons. The huge boulder was shifted by 45 meters, parallel to the shore, by Haiyan’s storm surge. The boulder was on the shore near the town of Hernani, Samar Island, near where the remarkable storm surge video linked below was taken. Haiyan’s extreme storm surge was amplified by a long-wave phenomenon called infragravity waves or surf beat, Dr. Engel explained to me in an email, and that he and other researchers are not convinced anymore that a storm surge in the traditional sense, due to strong winds piling up a big dome of water, was that important in Eastern Samar.

Video 1. Nickson Gensis, Plan Philippines Community Development Worker, filmed from the top floor of a boarding house what is probably the most remarkable video of storm surge ever taken, during Super Typhoon Haiyan in Hernani, in Eastern Samar, Philippines on November 8, 2013. There is a remarkable tsunami-like storm surge observed at 46 seconds into the video.

Earth's 7th Warmest November Puts 2014 on Pace to be Warmest Year on Record: NOAA

November 2014 was the seventh warmest November on record, and the year-to-date-period January - November was Earth's warmest such period since record keeping began in 1880, said NOAA's National Climatic Data Center (NCDC) on Monday. NASA rated November 2014 as the 8th warmest November on record. November ended a 3-month streak with record warm monthly temperatures—August, September, and October 2014 were all the warmest such months on record. Global ocean temperat...

Torrential Rains Dent Califonia's Worst Drought in at Least 1,200 Years

Torrential rains are falling across much of drought-scarred California, thanks to the wettest storm to affect the U.S. West Coast since at least October 2009. The heavy rains will put a noticeable dent in the state's three-year drought, which was the worst 3-year drought drought period in at least the past 1,200 years. This startling figure comes from a study of tree rings by researchers Daniel Griffin and Kevin Anchukaitis, How unusual is the 2012-2014 California d...

Huge Rainstorm Poised to Ease California's Thirst

The wettest storm to affect the U.S. West Coast since 2009 is gathering strength over the Pacific Ocean, and promises to bring much-needed drought relief to thirsty California Wednesday through Friday. Rainfall amounts of 3 - 8 inches are expected over most of Northern California, with snowfall amounts of 1 - 3 feet predicted in the Sierra Mountains. As noted by Wunderground weather historian Christopher C. Burt in his Monday post, California Drought Situation Impro...
