Weather in Malaysia provides early forecasts for UK, study finds

“It was once said that the flap of a butterfly’s wings in Brazil could set off a tornado in Texas, and our study provides new evidence of the remarkable interconnectedness of the world’s weather” – Robert Lee, University of Reading

Size of thunderstorm dome clouds may predict tornado intensity

The size of a bulge at the top of a thunderstorm’s anvil-shaped cloud may allow researchers to forecast the strength of tornadoes that spawn from such storms, according to a new study in AGU’s journal Geophysical Research Letters.

Advancing spring warmth could disrupt species migration, development

In a new study in the AGU journal Geophysical Research Letters, scientists found that in many areas of the U.S. springtime temperature thresholds important for plant and animal life cycles occur between six to 20 days earlier in the season than they did 70 years ago.

Satellite tracking shows how ships affect clouds and climate

By matching the movement of ships to the changes in clouds caused by their emissions, researchers have shown how strongly the two are connected.

New study complicates theory that ancient impact pierced Moon’s crust

A new study finds the crater’s crust mainly consists of a common lunar crustal mineral not detected in earlier analyses. The new results suggest the basin floor may not have exposed lunar mantle material as previously reported. “We are not seeing the mantle materials at the (Chang’E 4) landing site as expected,” said Hao Zhang, a planetary scientist at the China University of Geosciences, Wuhan, China, and a co-author of the new study.

Researchers find new ways for coral reef ecosystems to grow

Particulate organic matter from the open ocean has a bigger-than-expected role in the growth and health of coral reefs, say researchers studying declining coral reefs in Hawaii.

Streaks in Aurora Found to Map Features in Earth’s Radiation Environment

A special kind of streaked aurora has been found to track disturbances in near-Earth space from the ground. Known as structured diffuse aurora, it was recently discovered, with the help of NASA spacecraft and instruments, that these faint lights in the night sky can map the edges of the Van Allen radiation belts — hazardous concentric bands of charged particles encircling Earth.

Scientists forecasted late May tornado outbreak nearly four weeks before it ripped through U.S.

“This is the first documented successful long-range forecast for an extended period of tornado activity in the U.S.,” said lead author Victor Gensini, a professor of meteorology at Northern Illinois University.

Climate change is altering winter precipitation across the Northern Hemisphere

A team of scientists has successfully teased out the influence of human-caused climate change on wintertime precipitation over much of the last century, showing that the warming climate is significantly altering wintertime rainfall and snowfall across the Northern Hemisphere.

Study provides new clues to source of methane gas on Mars

A team of researchers led by scientists at York University’s Lassonde School of Engineering has created a model of how methane changes on Mars throughout the day by using data from a satellite, the ExoMars Trace Gas Orbiter and the Curiosity Rover. In the past, each had measured significantly different amounts of methane on Mars. The new measurements provide more clues that could help to understand what processes are important in creating the methane coming from a large 154 km- wide crater on the planet, Gale crater.
