Increases in extreme humid-heat disproportionately affect populated regions

13. Oktoober 2021 - 17:46
The world is not only getting hotter but also more humid and new research shows people living in areas where humid-heat extremes are already a significant hazard are bearing the brunt of the impact.

Anticipated spill from deteriorating Red Sea oil tanker threatens public health

11. Oktoober 2021 - 18:08
A massive prospective spill from a deserted oil tanker in the Red Sea could lead to catastrophic public health effects in war-torn Yemen and neighboring countries unless urgent action is taken, according to a new study.

A new proposed scheme towards seamless detection of cutoff lows and preexisting troughs

11. Oktoober 2021 - 16:13
A new automated numerical scheme is proposed for upper tropospheric cyclones (cutoff lows) and their earlier development stage as troughs (preexisting troughs). The proposed scheme has the capacity of early stage detection and can extract locations with transitions that are as smooth as possible and estimate their intensities, sizes, and even the local background flows behind them in a consistent and integrated manner using non-preprocessed (snapshot) basic weather data consisting of geopotential height fields.

Feather phenomenon: Radar indicates stronger hurricanes trap, transport more birds

6. Oktoober 2021 - 21:34
Whether birds get caged in the eye of a hurricane may depend on the intensity and totality of the chaos beyond the calm, says a novel study.

Exposure to deadly urban heat worldwide has tripled in recent decades, says study

4. Oktoober 2021 - 22:37
A new study of more than 13,000 cities worldwide has found that the number of person-days in which inhabitants are exposed to extreme combinations of heat and humidity has tripled since the 1980s. The authors say the trend, which now affects nearly a quarter of the world's population, is the combined result of both rising temperatures and booming urban population growth.

Bigleaf maple decline tied to hotter, drier summers in Washington state, U.S.

30. September 2021 - 18:11
A new study has found that recent bigleaf maple die-off in Washington is linked to hotter, drier summers that predispose this species to decline. These conditions essentially weaken the tree's immune system, making it easier to succumb to other stressors and diseases.

Coastal Northeastern US is a global warming hotspot; 2 degrees Celsius of summer warming has already occurred

23. September 2021 - 18:56
New research reveals not only that the coastal Northeast -- from Maine to Delaware -- is heating faster than most regions of North America, but that this heating is linked to drastic alterations in the ocean and atmospheric conditions over the North Atlantic.

Artificial intelligence may be set to reveal climate-change tipping points

23. September 2021 - 15:29
Researchers are developing artificial intelligence that could assess climate change tipping points. The deep learning algorithm could act as an early warning system against runaway climate change.

Missing wind variability means future impacts of climate change may be underestimated in Europe and North America

20. September 2021 - 15:21
Extratropical winds have a strong influence on climate in extratropical regions, and are known to vary from decade to decade. However, their variability is currently not factored into climate models making predictions for future climates in these regions. Researchers inserted these into predictions for how extratropical climates will change by the middle of the century, and found uncertainty increased significantly, meaning unusually hot, cold, dry or wet decades are likely to be more frequent here than previously thought.

How do higher waves cause more ice clouds? Research expedition into arctic sea explains

17. September 2021 - 16:04
Global warming is causing a rapid decline in sea-ice area, which affects weather patterns and, surprisingly, increases wave height in the Arctic. In a new study, Japanese scientists analyzed data from a 2018 research expedition into Chukchi Sea to demonstrate the peculiar link that exists between sea spray induced by high waves and the formation of ice-containing clouds. Their results pave the way for more accurate climate change and sea-ice models.

Proactive conservation of New Zealand blue whales

15. September 2021 - 20:51
Researchers have developed a method for forecasting the locations where a distinct population of New Zealand blue whales are most likely to occur up to three weeks in advance.

Better weather forecasting through satellite isotope data assimilation

15. September 2021 - 1:48
Real satellite water vapor isotope data were assimilated in a general circulation model to determine whether including these data could improve forecast accuracy at both the global and local scales. Overall, forecast accuracy was improved by several percentage points. The effect was especially notable for variables closely related to water vapor isotope fractionation, such as air temperature and specific humidity, and a local-scale pressure pattern over Japan in 2013 was modeled more clearly.

Jet stream changes could amplify weather extremes by 2060s

14. September 2021 - 5:02
The ribbon of fast winds familiar to air travelers between North America and Europe is a big influencer on weather in North America and Europe. By drilling deep into the Greenland Ice Sheet, researchers reconstructed the jet stream's past and found that climate-caused disruptions are likely to have drastic weather-related consequences for societies on both sides of the Atlantic.

Study explores link between earthquakes, rainfall and food insecurity in Nepal

11. September 2021 - 0:27
The effects of monsoon rainfall on food insecurity in Nepal vary by earthquake exposure, with regions that experienced both heavy earthquake shaking and abundant rainfall more likely to have an inadequate supply of nutritious food, according to new research.

Scientists solve mystery of icy plumes that may foretell deadly supercell storms

9. September 2021 - 21:12
The most devastating tornadoes are often preceded by a cloudy plume of ice and water vapor billowing above a severe thunderstorm. New research reveals the mechanism for these plumes could be tied to 'hydraulic jumps' -- a phenomenon Leonardo Da Vinci observed more than 500 years ago.

Extreme sea levels to become much more common worldwide as Earth warms

31. August 2021 - 18:19
A new study predicts that extreme sea levels -- exceptionally high seas due to the combination of tide, waves and storm surge -- along coastlines the world over will become 100 times more frequent by the end of the century in about half of the 7,283 locations studied.

Artificial intelligence to help predict Arctic sea ice loss

26. August 2021 - 15:17
A new AI (artificial intelligence) tool is set to enable scientists to more accurately forecast Arctic sea ice conditions months into the future. The improved predictions could underpin new early-warning systems that protect Arctic wildlife and coastal communities from the impacts of sea ice loss.
