A new study in the Journal of Geophysical Research: Atmospheres observes rare terrestrial gamma ray flashes produced by lightning strikes.

Even though the sun does not shine in Antarctica in winter, in some places snow on the glaciers can melt. The cause: warm wind.

Now, a new study in Geophysical Research Letters, a journal of the American Geophysical Union, analyzes what it would take for river-observing satellites to become an even more useful tool to mitigate flood damage and improve reservoir management globally in near real-time.

A major shift in western Arctic wind patterns occurred throughout the winter of 2017 and the resulting changes in sea ice movement are possible indicators of a changing climate, according to authors of a new study.

A new study finds the fires that spread throughout North America last summer burned so powerfully their smoke pushed all the way into the stratosphere, circled the globe in roughly two weeks and remained in the stratosphere at measurable levels for several months.

A new study identifies a method for predicting the likelihood of damaging hailstorms in the United States—up to three weeks in advance. Hail is the most economically destructive hazard posed by severe thunderstorms, producing on average billions of dollars in U.S. losses each year, including damage to roofs, homes and especially crops.

A new study has found that dust, not spring warmth, controls the pace of spring snowmelt that feeds the headwaters of the Colorado River.

Sea levels around the world have risen by 1.7 millimeters (0.07 inches) on average each year since 1880, but in recent years, scientists have observed a rapid increase in sea level in the north Indian Ocean. Tide gauge records and other datasets reveal the pace of sea level rise in the north Indian Ocean has accelerated to 3.1 millimeters (0.12 inches) per year within the last three decades. The accelerating sea level rise has confounded scientists but new research claims weakening of South Asian monsoons may be to blame.

Seismic waves generated by tornadoes when they touch down could be used to measure a twister’s intensity, according to a new study that examined the May 2011 Joplin tornado. The findings could open the door to devising more accurate methods to study tornadoes from the ground.

In April of 1815, the volcanic eruption of Mount Tambora in Indonesia caused a global decrease in temperatures for the following few years, and 1816 came to be known as the “year without a summer.” New England states were particularly hard hit by these temperature changes, which significantly affected agriculture production and quality of life. Alongside his journal entries, Reverend Jonathan Fisher of Blue Hill, Maine sketched the sunspots during the summer of 1816, thinking they might be responsible for the cold summer temperatures.
