    on June 25, 2018 at 5:09 pm

    Potential changes in the frequency and intensity of storms off the coast of the UK and around the world could have a 'catastrophic impact' on the livelihood of fishermen and sustainability of fishing industries, research has shown. […]

  • Hurricanes are slowing down, and that's bad news
    on June 8, 2018 at 4:32 am

    Some hurricanes are moving more slowly, spending increased time over land and leading to catastrophic local rainfall and flooding, according to a new study. […]

  • Reconstructing longest American water level, instrumented flood record, in Boston Harbor
    on June 1, 2018 at 5:47 pm

    Using newly-discovered archival measurements to construct an instrumental record of water levels and storm tides in Boston since 1825, researchers report that local averaged relative sea level rose by nearly a foot (0.28 meters) over the past 200 years, with the greatest increase occurring since 1920. The work also highlights tides and their significant effect on flooding in the city. […]

  • Study estimates increased death rate in Puerto Rico in months after Hurricane Maria
    on May 31, 2018 at 12:42 pm

  • Lightning in the eyewall of a hurricane beamed antimatter toward the ground
    on May 21, 2018 at 5:15 pm

    Hurricane Patricia, which battered the west coast of Mexico in 2015, was the most intense tropical cyclone ever recorded in the Western Hemisphere. Amid the extreme violence of the storm, scientists observed something new: a downward beam of positrons, the antimatter counterpart of electrons, creating a burst of powerful gamma-rays and X-rays. […]

  • Breakthrough in understanding rare lightning-triggered gamma-rays
    on May 17, 2018 at 2:22 pm

    The Telescope Array detected 10 bursts of downward terrestrial gamma-ray flashes (TGFs) between 2014 and 2016, more events than have been observed in rest of the world combined. They are the first to detect downward TGFs at the beginning of cloud-to-ground lightning, and to show where they originated inside thunderstorms. The array is by far the only facility capable of documenting the full TGF 'footprint' on the ground. […]

  • Record-breaking ocean heat fueled Hurricane Harvey
    on May 10, 2018 at 5:30 pm

    Record-hot Gulf of Mexico waters supercharged Hurricane Harvey, fueling it with vast stores of water and setting the stage for devastating flooding after it stalled near Houston. […]

  • Decoding tornadoes' infrasound waves
    on May 8, 2018 at 12:15 pm

  • Winter wave heights and extreme storms on the rise in Western Europe
    on April 24, 2018 at 12:39 pm

    Study reveals average winter wave heights along the Atlantic coast of Western Europe have been rising for almost seven decades. […]

  • Silent marine robots record sounds underwater
    on April 10, 2018 at 12:42 pm

    Silent marine robots that record sounds underwater are allowing researchers to listen to the oceans as never before. While pilot whales make whistles, buzzes and clicks, pods of hunting dolphins create high-pitched echolocation clicks and larger species such as sperm whales make louder, slower clicks. As well as eavesdropping on marine life, the recordings can be used to measure sea-surface wind speed and monitor storms. The research will be presented at the General Assembly of the European Geosciences Union, Vienna. […]

  • Unprecedented psychological distress months after Hurricane Harvey
    on April 4, 2018 at 6:34 pm

    Four months after Hurricane Harvey soaked the Houston area and displaced more than a third of the population, an alarming 52 percent of Harris County residents said they were still struggling to recover. […]

  • Hawaiian-language newspapers illuminate an 1871 hurricane
    on April 4, 2018 at 3:48 pm

    A major hurricane struck the islands of Hawai'i and Maui on Aug. 9, 1871, and wrought widespread destruction from Hilo to Lahaina. A recent study revealed how historical Hawaiian-language newspapers expand knowledge of this and other natural disasters of the past. […]

  • Half a degree more global warming could flood out 5 million more people
    on March 15, 2018 at 3:06 pm

    A new study finds that by 2150, the seemingly small difference between a global temperature increase of 1.5 and 2.0 degrees Celsius would mean the permanent inundation of lands currently home to about 5 million people, including 60,000 who live on small island nations. […]

  • Wind moves microinvertebrates across desert
    on March 13, 2018 at 7:21 pm

    Research has yielded the first evidence of how waterborne microinvertebrates move across vast expanses of arid desert. A new study details for the first time how high desert winds disperse small invertebrates and how they colonize hydrologically disconnected basins throughout the region. […]

    on March 9, 2018 at 5:51 pm

    A new study shows that electrically charging airplanes may reduce their risk of being struck by lightning. […]

  • New 3-D measurements improve understanding of geomagnetic storm hazards
    on March 8, 2018 at 6:33 pm

    Measurements of the three-dimensional structure of Earth, as opposed to the one-dimensional models typically used, can help scientists more accurately determine which areas of the United States are most vulnerable to blackouts during hazardous geomagnetic storms. […]

  • Storm waves can move boulders we thought only tsunamis had the power to shift
    on February 28, 2018 at 2:21 pm

    It's not just tsunamis that can change the landscape: storms shifted giant boulders four times the size of a house on the coast of Ireland in the winter of 2013-14, leading researchers to rethink the maximum energy storm waves can have - and the damage they can do. Four years ago, storms moved huge boulders along the west coast of Ireland. The same storms shifted smaller ones as high as 26 meters above high water and 222 meters inland. Many of the boulders moved were heavier than 100 tons, and the largest moved was 620 tons - the equivalent of six blue whales or four single-story houses. It was previously assumed that only tsunamis could move boulders of the size seen displaced in Ireland, but the new paper provides direct evidence that storm waves can do this kind of work. […]

  • Series of storms more than 150 years ago caused extensive erosion of the Carpinteria Salt Marsh
    on February 26, 2018 at 8:26 pm

    Flooding isn't new to the Santa Barbara coastline. However, the inundation doesn't always come from the mountains as it did last month in Montecito. Back in 1861-2, a series of large storms washed beach sand more than a quarter mile inland into what today is the Carpinteria Salt Marsh. Although historical accounts document the inland flooding, little has been known about how those storms impacted a now heavily developed California coast. […]

  • Geophysicists and atmospheric scientists partner to track typhoons' seismic footprints
    on February 15, 2018 at 6:11 pm

    A remarkable collaboration between atmospheric science and geophysics could change the way we think about storms and seismicity, and could lead to an answer to the often-asked 'Are hurricanes getting stronger?' The team has identified the seismic footprint of typhoons and hurricanes, which allows climate scientists to add decades to their dataset of powerful storms. […]

  • Hurricanes Irma and Maria temporarily altered choruses of land and sea animals
    on February 15, 2018 at 5:50 pm

    Audio recordings of Hurricanes Irma and Maria's passage over Puerto Rico document how the calls of coastal critters changed in response to the deadly storms. The hurricanes caused a major disruption in the acoustic activity of snapping shrimp, a reduction in insect and bird sounds, and potentially an intensification of fish choruses, according to new research. […]

  • Don't blame hurricanes for most big storm surges in Northeast
    on February 15, 2018 at 3:57 pm

    Hurricanes spawn most of the largest storm surges in the northeastern US, right? Wrong, according to a new study. Extratropical cyclones, including nor'easters and other non-tropical storms, generate most of the large storm surges in the Northeast, according to the new study. They include a freak November 1950 storm and devastating nor'easters in March 1962 and December 1992. […]

  • Lightning storms less likely in a warming planet, study suggests
    on February 12, 2018 at 4:17 pm
