Pacific Ocean typhoons could be intensifying more than previously projected
Changes to the uppermost layer of Earth’s oceans due to rising temperatures are likely causing an increase in intense Pacific Ocean typhoons, suggesting strong typhoons may occur more frequently than scientists project in the coming decades, according to new research.

Study finds unexpected levels of bromine in power plant exhaust
Some coal-fired power plants in the United States emit gases that may produce harmful compounds in drinking water and can have significant effects on the atmosphere, according to new research. A new study published in the Journal of Geophysical Research: Atmospheres, a journal of the American Geophysical Union, finds unexpectedly high levels of reactive bromine-containing chemicals in plumes emitted by coal-fired power plants not using a particular type of exhaust-cleaning technology.

Research provides new clues to origins of mysterious atmospheric waves in Antarctica
Two years after a research team discovered a previously unknown class of waves rippling continuously through the upper Antarctic atmosphere, they’ve uncovered tantalizing clues to the waves’ origins. The interdisciplinary science team’s work to understand the formation of “persistent gravity waves” promises to help researchers better understand connections between the layers of Earth’s atmosphere—helping form a more complete understanding of air circulation around the world.

Researchers find an easier way to simulate cloud cover
Clouds are an inspiration to most of us, but a nightmare for climate scientists. Clouds are exceptionally complex creatures, and that complexity makes it difficult to predict how and where they’ll form – which is unfortunate, since those predictions are essential to understanding precipitation patterns and how our climate will change in the future.

Organic aerosols in remote areas have shorter lives than scientists assumed
Scientists find the lifetime of organic aerosols in the upper atmosphere is on the order of 10 days, far shorter than scientists previously assumed.

Threat to the ozone layer by future volcanic eruptions greater than previously thought
As the CFCs slowly degrade over the coming decades, so too should the volcano’s ozone-destroying power. However, new research shows that the volcanic risk to the ozone layer will persist for decades longer than previously believed.

Some clouds filled with ice lollipops
A cloud full of lollipops may sound like the most delicious carnival treat ever… except this cloud’s lollipops are made of ice. Scientists spotted the lollipop-shaped ice crystals during a research flight in southwest England. The researchers flew through a large cloud system in 2009 to better understand how ice forms at relatively mild temperatures.

Lightning could be sending powerful electromagnetic radiation into space
During a thunderstorm, lightning that hits the ground may be shooting powerful electromagnetic radiation skyward. At least that is the new theory from a physicist in China who specializes in laser-plasma interactions.

Horse hair can help improve accuracy of climate data
In a new study, researchers used horsehair to determine that latitude influences certain climate measurements. The finding could help scientists find other factors potentially affecting climate measurements and to better understand how to compare climate records from different locations, according to the study’s authors.
