A first-of-its-kind study analyzing flood risk to hospitals on America’s Atlantic and Gulf Coasts following category 1-4 storms has found that even a relatively weak storm poses a serious flood risk to hospitals, while the expected rise in sea levels this century due to climate change will increase the odds of hospital flooding by 22%.
Dr Aaron Bernstein, senior author and director of the Center for Climate, Health, and the Global Environment (C-CHANGE) at Harvard University, said, “We now have a better sense of which hospitals are likely to flood from a hurricane today and those that need to prepare for greater risks in the future.
Professor Lesley Gray is set to take up her role as the new president of the Royal Meteorological Society (RMetS) on October 1, 2022.
Departing president Professor David Griggs will take up the post of vice-president alongside current vice-presidents Robert Varley and Catherine Senior and vice-president for Scotland Gary Johnston.
Gray works as an atmospheric researcher at the National Centre of Atmospheric Science (NCAS) unit based in the University of Oxford Physics Department. She is a professor of climate dynamics. Her expertise is in understanding and modeling dynamical processes in the stratosphere with an emphasis on natural variability and its impacts at the Earth’s surface.
Australia’s Bureau of Meteorology (BoM) has completed the installation of a new dual-polarized Doppler weather radar at Richmond, North Queensland.
Matt Collopy, acting group executive, community services, BoM, said, “As well as improved coverage across the Diamantina, Cooper, Flinders and parts of the Norman and Gilbert River catchments, radar coverage will now extend along the significant supply route of Flinders Highway, from Mount Isa to Townsville. This will improve the Bureau’s ability to make weather observations in the region and to warn the community about the potential impacts of severe weather.”
Collopy said the technology would benefit communities including Hughenden, Winton, Georgetown and Julia Creek, as well as supporting local industry such as agriculture, transportation and tourism in making better decisions when preparing for severe weather.
A research team from Russ College’s School of Electrical Engineering and Computer Science (EECS) at Ohio University has begun rolling out a network of ground-based sensors to create a low-altitude weather network (LAWN) in support of advanced air mobility (AAM) projects in the region.
Chad Mourning, assistant professor at EECS, and his team completed the installation of the first sensor unit in August, with plans to install a further 25 units at the local airport.
Mourning said, “We have an issue where we go to the Weather Channel and the satellite is telling you about the weather at 10,000ft [3,048m].
Weather and environmental measurement specialist Vaisala has unveiled its new Xweather environment forecast and observation service, leveraging its holistic range of sensor technology to provide critical and actionable insights for extreme weather.
Created for businesses and developers whose products, operations or customers depend on high-quality weather and environmental information, Xweather provides a suite of observation-enhanced SaaS (Solution as a Service) and DaaS (Data as a Service) services that provide meteorological information ranging from road conditions and air quality to heat wave detection and lightning strikes.
Samuli Hänninen, global head of Xweather at Vaisala, said, “Now it’s time to accelerate our efforts with actionable data that can help us predict the future.
Marine drone developer Saildrone has released footage taken by one of its uncrewed surface vehicles (USV) from inside Hurricane Fiona (Category 4) as it barreled across the Atlantic Ocean.
The Saildrone Explorer SD 1078 was directed into the midst of Hurricane Fiona, which is the first Category 4 storm of the 2022 season. SD 1078 battled with 15m waves and winds measuring over 100mph to collect scientific data.
Inside the storm, SD 1078 sailed at sustained speeds of more than 9mph, reaching a peak speed of 39.7mph while surfing down a large wave.
SD 1078 is one of seven ‘hurricane’ saildrones that have been operating in the Atlantic Ocean and Gulf of Mexico during this hurricane season.
NOAA-funded social science research has shown that the Spanish words currently used by the US National Weather Service and the Federal Emergency Management Agency (FEMA) for tornado warnings do not carry the same level of urgency needed to spur protective action as their English counterparts.
Joseph Trujillo-Falcón, lead author and graduate research assistant for NOAA’s Cooperative Institute for Severe and High-Impact Weather Research and Operations (CIWRO), said, “Our research shows significant inequities in understanding watches and warnings between English and Spanish speakers. To reduce this language barrier, our data supports using the Spanish word ‘vigilancia’ for a tornado watch and the Spanish word ‘alerta’ for a tornado warning.”
NOAA currently uses the Spanish word ‘vigilancia’ for a watch and ‘aviso’ for a warning.
An international team of scientists has announced that it is now able to measure the thickness of ice in the Arctic Sea 365 days a year using satellites.
The solution was developed by an international team that includes the UK’s National Oceanography Centre (NOC) and the Arctic University of Norway (UiT), along with partners from the USA, Canada and Germany.
Sea ice poses a critical hazard to ships, particularly small and medium-sized vessels, with accurate information about the location and thickness of ice needed in advance. The Norwegian Meteorological Institute provides sea ice forecasts for the Arctic but previously lacked reliable information concerning ice thickness for the summer months.
