These cloud-to-ground strikes during little to no rainfall were previously thought to pose wildfire danger only if occurring with less than 2.5 mm of rain in a day (about 0.10 inches). A new study of lightning-ignited wildfires in the U.S. West found the strikes caused wildfires despite up to 7.7 mm (about 0.3 inches) of precipitation. While still a low amount of rain, the more accurate estimation could help responders detect fires earlier, especially those known as 'holdovers,' which can smolder for many days before exploding into full-blown wildfires.

Until now, there existed very few freely available computer models designed to estimate the economic costs of such events, but a team of researchers has recently announced the completion of an open-source model that stands to help countries with high tropical cyclone risks better calculate just how much those storms will impact their people and their economies.

They used this model to understand why storm geysers form, what conditions tend to make them worse, and what city planners can do to prevent them from occurring. The authors say the best cure for a storm geyser is bigger pipes; however, that advice is little help to cities with existing pipeline infrastructure. In these systems, the focus must be on minimizing the potential damage by reducing the height of the geysers, the volume of expelled water, or the resulting damage to the pipeline.

High-energy events, such as lightning, can cause unique chemical reactions. In this instance, the result is a new material -- one that is transitional between space minerals and minerals found on Earth.

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.

However, from December 2021 to January 2022, researchers did not find a single skua nest on Svarthamaren, one of the regions where the birds go to raise their young. Similarly, the number of Antarctic petrel and snow petrel nests dropped to almost zero.

A new study demonstrates that a recently developed scale for atmospheric river intensity (akin to the hurricane scale) can be used to rank atmospheric rivers and identify hotspots of the most intense atmospheric rivers not only along the U.S. West Coast but also worldwide.

A new technique combining underused satellite and radar data in weather models may improve these predictions, according to a team of scientists.

Therefore, researchers have studied the wind speeds that different seabird species can withstand. The team was able to show that the individual species are well adapted to the average wind conditions in their breeding grounds, but use different strategies to avoid flying through the storm. Within their research, one behavior of the albatrosses particularly surprised the scientists.

In some areas such double hits could occur as frequently as once every 3 years.

For years, the brightness symmetry between hemispheres remained a mystery. In a new study, researchers reveal a strong correlation between storm intensity, cloudiness and the solar energy reflection rate in each hemisphere. They offer a solution to the mystery, alongside an assessment of how climate change might alter the reflection rate in the future.

A new study found powerful storms called atmospheric rivers are increasingly reaching the Arctic in winter, slowing sea ice recovery and accounting for a third of all winter sea ice decline, according to a team led by Penn State scientists.

But they're also subject to intense storms that can cause 'windthrow' -- the uprooting or breaking of trees. A new study finds that more extreme thunderstorms from climate change will likely cause a greater number of large windthrow events in the Amazon, which could impact the rainforest's ability to serve as a carbon sink.

The path was easy to follow on land, but debris and infrastructure failures also diminished the river's water quality and led to the death of roughly half the gulf sturgeon population there. A study reveals new details in how a decrease in oxygen levels affected the river's ability to sustain life in the days following the historic Category 5 storm.

Researchers explained variations in tree mortality over a five-year period by analyzing drone images of one of the most-studied tropical forests in the world, Barro Colorado Island in Panama.

A new technique using readily available data reduces forecast errors and could improve track, intensity and rainfall forecasts for future storms like Hurricane Harvey, according to scientists.

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.

What puzzles the researchers is that the storm took place during one of the sun's more quiet phases -- during which it is generally believed our planet is less exposed to such events.
