With the Arase satellite in a perfect observing position, researchers watched the plasmasphere shrink to a fraction of its usual size and take days to rebuild. The event pushed auroras far beyond their normal boundaries and revealed that a rare “negative storm” in the ionosphere dramatically slowed the atmosphere’s ability to recover. These observations offer valuable insight into how extreme solar activity disrupts satellites, GPS signals, and communication systems.

These consist of sediment layers composed of coarse particles, which are different from the finer sediments associated with good weather. In the Caribbean, an international research team has now examined such sediments using a 30 m long core from a 'blue hole' offshore Belize. The analysis shows that over the past 5,700 years, the frequency of tropical storms and hurricanes in the region has steadily increased. For the 21st century, the research team predicts a significant rise in regional storm frequency as a result of climate change.

But climate change is making it happen more frequently, with ever-larger icebergs in the waters around Antarctica. Researchers are studying the routes that icebergs followed during geological periods of rapid ice cap deterioration, such as the ends of ice ages. That provides crucial information about the effect of melting icebergs on the oceans, and its consequences for the future. In the process, they also found an explanation for the mysterious discovery of ancient material from Antarctica near South Orkney, an island to the southwest of South Georgia.

A professor of entomology and plant pathology has been studying silverleaf nightshade for more than a decade. New findings have shown that the more silverleaf nightshade was mowed, the more it developed ways to avoid destruction. The taproot went down further, nearly 5 feet deep, in the first generation of mowed plants. More spikes popped out on the stem as a defense against caterpillars feeding on the flowers. The flowers became more toxic to caterpillars, leading to less pressure from natural predators.

A new study has found that women who lived along the coast of Aceh, Indonesia when it was hit by waves from the 2004 tsunami have lower cortisol levels 14 years later than women who lived in other, nearby coastal communities that were not directly affected. Cortisol is a stress hormone produced by the adrenal glands. Cortisol levels rise in response to stress as part of the fight or flight response, but consistently elevated stress can result in dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis. The study links the stresses from exposure to the tsunami to 'burnout' of the HPA-axis manifest in low cortisol levels over the long-term.

Weather researchers have given storm forecasters a powerful new tool to improve confidence in their forecasts and potentially save lives. Over the last several years, Russ Schumacher, professor in the Department of Atmospheric Science and Colorado State Climatologist, has led a team developing a sophisticated machine learning model for advancing skillful prediction of hazardous weather across the continental United States. First trained on historical records of excessive rainfall, the model is now smart enough to make accurate predictions of events like tornadoes and hail four to eight days in advance -- the crucial sweet spot for forecasters to get information out to the public so they can prepare. The model is called CSU-MLP, or Colorado State University-Machine Learning Probabilities.

Now, a team of scientists has published one of the first results that shows the effects of natural disasters may have molecularly accelerated aging in the monkeys' immune systems.

Intense rain associated with narrow cold-frontal rainbands may last only a few minutes at a particular location, yet the rain can cause catastrophic flash flooding, debris flows and landslides, and can occur along with tornadoes and severe thunderstorms.

The study finds that North Atlantic hurricanes have indeed increased in frequency over the last 150 years, similar to what historical records have shown.

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.

A new method now makes it possible to determine sea level changes with millimeter accuracy even in coastal areas and in case of sea ice coverage. This is of vital importance for planning protective measures.
