Tropical air circulation drives fall warming on Antarctic Peninsula
(Phys.org) —The eastern side of the Antarctic Peninsula, a finger of the southern polar continent that juts toward South America, has experienced summer warming of perhaps a half-degree per decade – a ...
Tropical western Pacific regional cloudiness appears to form on its own schedule
(Phys.org) —Tropical cloudiness has its own timeline. That's what researchers at Pacific Northwest National Laboratory found when they compared development of turbulent clouds to the timing of the atmospheric ...
Rising temperature difference between hemispheres could dramatically shift rainfall patterns in tropics
(Phys.org) —One often ignored consequence of global climate change is that the Northern Hemisphere is becoming warmer than the Southern Hemisphere, which could significantly alter tropical precipitation ...
Heatwaves: Longer, hotter and more common
(Phys.org) —Australia's summer heatwaves are lasting longer and have been increasing in number over the past 60 years, a UNSW study shows.
Study of Midwest finds increase in heavy rainfalls over 60 years
Heavy rains have become more frequent in the upper Midwest over the past 60 years, according to a study from the University of Iowa. The trend appears to hold true even with the current drought plaguing the region, the study's ...
Study predicts lag in summer rains over parts of US and Mexico
A delay in the summer monsoon rains that fall over the southwestern United States and northwestern Mexico is expected in the coming decades according to a new study in the Journal of Geophysical Research. The No ...
Forecast is for more snow in polar regions, less for the rest of us
A new climate model predicts an increase in snowfall for the Earth's polar regions and highest altitudes, but an overall drop in snowfall for the globe, as carbon dioxide levels rise over the next century.
Team finds new way to identify which El Nino events will have biggest impact on U.S. winter weather
(Phys.org)—Weather forecasters have long known that El Niño events can throw seasonal climate patterns off kilter, particularly during winter months. Now, new research from NOAA and the University of Washington ...
Increases in extreme rainfall linked to global warming
(Phys.org)—A worldwide review of global rainfall data led by the University of Adelaide has found that the intensity of the most extreme rainfall events is increasing across the globe as temperatures rise.
Mid-level tropical clouds form differently during active and break monsoon periods
(Phys.org)—Scientists at Pacific Northwest National Laboratory employed a method to understand how and when mid-level clouds, hovering between their conspicuous "siblings," form in the tropics. Low and ...
Researcher predicts more intense North Atlantic tropical storms
Tropical storms that make their way into the North Atlantic, and possibly strike the East Coast of the United States, likely will become more intense during the rest of this century.
Plants and soils could exacerbate climate change as global climate warms
Scientists from the American Meteorological Society (AMS) and University of California, Berkeley have demonstrated that plants and soils could release large amounts of carbon dioxide as global climate warms. This finding ...
Researchers develop tool to assess regional risks of climate change, potential impacts on infrastructure and planning
Climate scientists cannot attribute any single weather event—whether a drought, wildfire or extreme storm—to climate change. But extreme events, such as Hurricane Sandy, are glimpses of the types of occurrences ...
Ice core reveals unusual decline in eastern Australian rainfall
Researchers from the ACE CRC and the Australian Antarctic Division have found evidence from ice cores of a long term decline in average annual rainfall in eastern Australia, with records revealing that rainfall ...
1,000 years of climate data confirms Australia's warming
In the first study of its kind in Australasia, scientists used 27 natural climate records to create the first large-scale temperature reconstruction for the region over the past 1,000 years.
