To forecast winter rainfall in the Southwest, look to New Zealand in the summer

13. Juuni 2018 - 17:19
Scientists have discovered an atmospheric teleconnection that allows them to accurately predict winter precipitation in the southwestern United States by measuring summer sea surface temperatures near New Zealand.

Researchers investigate the correlation between wind and wave height in the Arctic Ocean

12. Juuni 2018 - 15:00
An international research team has found an increase in high waves and winds in the ice-free waters of the Arctic Ocean, a potentially dangerous navigational tipping point for the 'new and unusual' state of the waters.

Warmer climate will dramatically increase the volatility of global corn crops

11. Juuni 2018 - 22:27
Warmer temperatures by the end of this century will dramatically increase the volatility in global supplies of corn, the most widely grown crop in the world.

Hurricanes are slowing down, and that's bad news

8. Juuni 2018 - 7:32
Some hurricanes are moving more slowly, spending increased time over land and leading to catastrophic local rainfall and flooding, according to a new study.

Injuries and loss of life boost religious faith after disasters

6. Juuni 2018 - 0:25
Weather-related disasters can make people more religious but it depends on the toll they inflict, suggests new research. If a disaster injures a significant number of people, it can strengthen religiosity among those who are already religious. But if a disaster inflicts mostly economic damage, the opposite effect applies.

Storm's coming: New technique for simulation of extreme weather events

4. Juuni 2018 - 18:24
Scientists have developed a new method for generating data for ensemble simulation of extreme weather phenomena. He tested the method in simulation of a typhoon and a global warming simulation, and successfully created the necessary range of data in each case. The method has high computational stability and can be applied to any type of extreme weather event or other types of problems such as land cover change.

Climate change increasing risks of lightning-ignited fires

31. Mai 2018 - 15:44
Fires ignited by lightning have and will likely continue to increase across the Mediterranean and temperate regions in the Southern Hemisphere under a warmer climate, according to a new study co-led by a Portland State University researcher.

Huddling for survival: monkeys with more social partners can winter better

30. Mai 2018 - 18:31
Wild monkeys which have more social partners form larger huddles in adverse weather and have a better chance of surviving winter, new research has found. The study is the first to show that such social bonding may be connected to higher 'fitness' -- the term used by scientists to measure of how well animals can cope with their local ecological conditions, usually measured by reproductive success and survival.

Increasing heat is driving off clouds that dampen California wildfires

30. Mai 2018 - 18:29
Sunny California may be getting too sunny. Increasing summer temperatures brought on by a combination of intensifying urbanization and warming climate are driving off once common low-lying morning clouds in many southern coastal areas of the state, leading to increased risk of wildfires, says a new study.

The case of the relativistic particles solved with NASA missions

29. Mai 2018 - 21:09
Encircling Earth are two enormous rings -- called the Van Allen radiation belts -- of highly energized ions and electrons. Various processes can accelerate these particles to relativistic speeds, which endanger spacecraft unlucky enough to enter these giant bands of damaging radiation. Scientists had previously identified certain factors that might cause particles in the belts to become highly energized, but they had not known which cause dominates.

China floods to hit US economy: Climate effects through trade chains

28. Mai 2018 - 22:19
Fluvial floods will increase due to human-made climate change, in particular in China. This might raise direct and indirect economic losses along the global supply and trade chains. The US is susceptible to indirect climate-related economic losses due to its negative trade balance with China. Trump's tariffs might further reduce the resilience of the US economy.

New theory finds 'traffic jams' in jet stream cause abnormal weather patterns

24. Mai 2018 - 21:16
A study offers an explanation for a mysterious and sometimes deadly weather pattern in which the jet stream, the global air currents that circle the Earth, stalls out over a region. Much like highways, the jet stream has a capacity, researchers said, and when it's exceeded, blockages form that are remarkably similar to traffic jams -- and climate forecasters can use the same math to model them both.

Some desert creatures may be able to cope with climate change better than expected

24. Mai 2018 - 21:15
Ecologists have no doubt that climate change will affect the earth's animals and plants. But how exactly? This is often hard to predict. There are already indications that some species are shifting their distribution range. But it is much less clear how individual animals and populations are responding to the changes. Scientists have been studying nocturnal desert geckos to see how they are adapting to climatic changes.

Giant clams tell the story of past typhoons

Floridians could far far more frequent, intense Heatwaves

23. Mai 2018 - 16:12
By the late 21st century, if atmospheric greenhouse gas concentrations reach worst-case projections, Floridians could experience summer heatwaves three times more frequently, and each heatwave could last six times longer and be much hotter than at present, according to new research.
