Global warming to keep driving winds poleward, deep sea dust suggests

Global warming to keep driving winds poleward, deep sea dust suggests

Science
Jan. 6 (UPI) -- New analysis of dust grains dredged from the bottom of the North Pacific suggests the westerlies moved toward the poles during the warmest stretches of the Pliocene, between 3 and 5 million years ago. Scientists on Wednesday published their findings in the journal Nature. Advertisement The westerlies, sometimes called the anti-trades, are a series of prevailing winds blowing from west to east across the middle latitudes. Over the last several decades, scientists have noticed the winds slowly migrating away from the equator, inching into higher and higher latitudes. "Much of the work that has been done in describing changes to the westerlies over the last several decades suggests that warming caused by greenhouse gases may be a major contributor to this movement of the wes...
Epsilon to lash Bermuda with strong winds, heavy rain

Epsilon to lash Bermuda with strong winds, heavy rain

World
Oct. 21 -- After rapidly strengthening into a major hurricane on Wednesday, Epsilon weakened a bit overnight Thursday as it crept closer to Bermuda Forecasters warned that tropical storm conditions were expected in the country later in the day. Advertisement In its 5 p.m. EDT update, the National Hurricane Center said Epsilon weakened to a Category 1 hurricane, with 85 mph maximum sustained winds. The storm was 200 miles east of Bermuda at that time and was moving north-northwest at 9 mph. The 26th storm of the 2020 Atlantic hurricane season strengthened into a hurricane on Tuesday night and continued to rapidly intensify throughout the remainder of the night and early on Wednesday. On Wednesday afternoon, it became just the fourth major hurricane of the season when its maximum sustained ...
Gamma drifts north of Yucatan Peninsula after lashing Mexico with damaging winds, flooding rain

Gamma drifts north of Yucatan Peninsula after lashing Mexico with damaging winds, flooding rain

World
Oct. 5 (UPI) -- The record-breaking nature of the 2020 Atlantic Tropical Season continues as Tropical Storm Gamma meanders north of the Yucatan Peninsula early Monday after striking Mexico with strong winds and flooding rains over the weekend. Gamma became a tropical storm and gained its name on Friday evening as it strengthened in the northwestern Caribbean Sea, becoming only the second storm of its name to exist in Atlantic Basin history, and the earliest ever, beating out the Gamma of 2005. Advertisement The system made landfall at 12:45 p.m. EDT on Saturday near Tulum, Mexico, as a strong tropical storm. The National Hurricane Center said that a weather station at Xel-Ha Park, along the Yucatan coast just north of Tulum, reported sustained winds of 60 mph. In its 4 a.m CDT advisory o...
Astronomers observe stellar winds from aging stars in unprecedented detail

Astronomers observe stellar winds from aging stars in unprecedented detail

Science
Sept. 17 (UPI) -- Astronomers have captured high resolution images of stellar winds emanating from a diversity of aging stars. The observations, detailed Thursday in the journal Science, suggest the dramatic shapes of planetary nebulae are formed by interactions between stellar winds and nearby planets and stars. Advertisement As dying stars swell and cool, they expel particles and shed mass, producing stellar winds. As the red giants continue to age and evolve, they heat up again, casting off layers of ejected stellar material. Stellar radiation causes these sloughed layers to glow, creating what astronomers call planetary nebulae. Scientists have long struggled to explain the wide variety of shapes and colors that characterize planetary nebulae. "The sun, which will ultimately become a...

155mph winds as Hurricane Lorenzo creeps across Atlantic

World
Winds of 155mph have been recorded as record-breaking Hurricane Lorenzo creeps across the Atlantic.The hurricane set a record overnight for being the strongest ever to make it so far east, as it was officially recognised as a "category five" storm. The US National Hurricane Centre said that the storm has maximum sustained winds of 155mph (250kph) and is moving north towards the Azores, the Portuguese island chain.
