Science Daily September 9, 2021 The strongest supercell thunderstorms typically feature an above-anvil cirrus plume (AACP), which is a plume of ice and water vapor in the lower stratosphere that occurs downwind of the ambient stratospheric flow in the lee of overshooting deep convection. AACP-origin hydration of the stratosphere has a poorly constrained role in ozone destruction and surface warming. A team of researchers in the US (Stanford University, University of Wisconsin) used large eddy simulations corroborated by radar observations to understand the physics of AACP generation. They showed that the overshooting top of a simulated supercell can act as […]

Once in a lifetime floods to become regular occurrences by end of century
Science Daily December 2, 2020 Based on the anticipated greenhouse gas concentration by the end of the 21st century a team of researchers in the US (Stevens Institute of Technology, Princeton University) conducted high resolution simulations for different scenarios to find the probability of different flood levels being reached, assuming emissions remain at a high level. They studied how sea level rise and hurricane climatology change would impact the area in the future due to storm surge and wave hazards. They found that the historical 100-year flood level would become a nine-year flood level by mid-century (2030-2050) and a one-year […]
