California water managers vary in use of climate science

14. August 2018 - 14:59
Lack of climate change adaptation among water utilities can put water supplies and the people dependent on them at risk, especially in marginalized communities, a new article suggests.

Historic space weather could clarify what's next

13. August 2018 - 18:33
Scientists have discovered an underlying repeatable pattern in how space weather activity changes with the solar cycle - having analysed solar activity for the last half century.

New technique for modeling turbulence in the atmosphere

8. August 2018 - 0:10
Researchers have designed a computer model that more effectively calculates the behavior of atmospheric turbulence in complex environments, including cities, forests, deserts and mountainous regions.

Oregon has its share of fire storms

7. August 2018 - 21:49
Oregon, one state above California, is also having its share of fire storms and weather concerns. Five large fires/complexes are alight in the southwest corner of the state and all started on the same day with a region-wide lightning storm.

Rain-on-snow flood risk to increase in many mountain regions of the western U.S., Canada

6. August 2018 - 23:27
Flooding caused by rain falling on snowpack could more than double by the end of this century in some areas of the western United States and Canada due to climate change.

Radar better than weather balloon for measuring boundary layer

2. August 2018 - 21:18
Improving forecasting for a host of severe weather events may be possible thanks to a more comprehensive method for measuring the Earth's boundary layer depth.

Death toll from Hurricane Maria estimated to be larger than previously thought

2. August 2018 - 21:16
The number of people who died as a result of Hurricane Maria -- which hit Puerto Rico on Sept. 20, 2017 -- may be as high as 1,139, surpassing the official death count of 64, according to researchers.

Heatwave and climate change having negative impact on our soil say experts

2. August 2018 - 17:23
The recent heatwave and drought could be having a deeper, more negative effect on soil than we first realized say scientists. That's because organisms in soil are highly diverse and are responsible not only for producing the soil we need to grow crops, but also provide humans with many other benefits, such as cleaning water and regulating greenhouse gas emissions.

Climate change-driven droughts are getting hotter, study finds

1. August 2018 - 23:00
In a new study, researchers report that temperatures during droughts have been rising faster than in average climates in recent decades, and they point to concurrent changes in atmospheric water vapor as a driver of the surge.

Arctic cyclone limits the time-scale of precise sea-ice prediction in Northern Sea Route?

1. August 2018 - 16:37
Climate change has accelerated sea-ice retreat in the Arctic Ocean, leading to new opportunities for summer commercial maritime navigation along the Northern Sea Route. International researchers have demonstrated a new system for forecasting sea-ice thickness in early summer in the East Siberian Sea. The system was accurate up to 3 days ahead, representing high potential for use in operational maritime navigation of the Northern Sea Route.

What is causing more extreme precipitation in northeastern U.S.?

31. Juuli 2018 - 23:41
From Maine to West Virginia, the Northeast has seen a larger increase in extreme precipitation than anywhere else in the US. Prior research found that these heavy rain and snow events, defined as a day with about two inches of precipitation or more, have been 53 percent higher in the Northeast since 1996. A new study finds that hurricanes and tropical storms are the primary cause of this increase, followed by thunderstorms along fronts and extratropical cyclones like Nor'easters.

Solar flares disrupted radio communications during September 2017 Atlantic hurricanes

30. Juuli 2018 - 21:54
An unlucky coincidence of space and Earth weather in early September 2017 caused radio blackouts for hours during critical hurricane emergency response efforts, according to a new study. The new research, which details how the events on the Sun and Earth unfolded side-by-side, could aid in the development of space weather forecasting and response, according to the study's authors.

Australia facing extremely intense rain storms

30. Juuli 2018 - 19:02
Large increase in sudden downpours in the last 50 years, with the amount of water falling in hourly rain storms (for example thunderstorms) increasing at a rate 2 to 3 times higher than expected.

Europe may thrive on renewable energy despite unpredictable weather

26. Juuli 2018 - 23:12
Researchers have shown how long-term weather patterns affect wind and solar renewable energy technologies across Europe. The work suggests that despite the unpredictable nature of wind and solar energy, the European power system can comfortably generate at least 35 percent of its electricity using these renewables alone without major impacts on prices or system stability.

Cold wave reveals potential benefits of urban heat islands

23. Juuli 2018 - 21:30
Researchers have found that the urban heat island effect -- cities are hotter in the summer than their surrounding areas -- also helps keep cities warmer during extreme cold. The findings have implications for urban planners in areas such as New York City or Chicago, which experience marked seasonal temperature swings.

Warming temperatures could increase suicide rates across the US and Mexico

23. Juuli 2018 - 21:28
By comparing historical temperature and suicide data, researchers found a strong correlation between warm weather and increased suicides. They estimate climate change could lead to suicide rate increases across the US and Mexico.

Wave energy converters are not geared towards the increase in energy over the last century

20. Juuli 2018 - 18:28
Wave energy converters are designed to generate the maximum energy possible in their location and take a typical year in the location as a reference. Researchers have been exploring how ocean energy in Ireland has evolved during the last century. The results reveal an increase of up to 40%, which directly affects the output of the converters.
