Tornado Alley shifting east

Meteorologist Dr. Harold Brooks appeared on AMHQ recently, speaking about Tornado Alley and his recent study about spatial trends in United States tornado frequency. While it's evident that tornadoes are shifting east, the reasons why this is happening are still...

'True polar wander' and Earth's ice ages

Rice University geophysicists have determined Earth shifted relative to its spin axis within the past 12 million years, which caused Greenland to move far enough toward the north pole to kick off the ice age that began about 3.2 million years ago. The study is based...

Large asteroid impact crater found under Hiawatha Glacier, Greenland

An international team of scientists announced a remarkable discovery of one of the youngest large asteroid impact craters on Earth. The crater is buried under 1 km (0.62 miles) of ice in a remote area of northwest Greenland. The finding was published in the November...

Two-step energy transfer in Earth's magnetosphere

Scientists have obtained in situ measurements of Earth's magnetosphere, demonstrating a phenomenon that's long been thought to happen but not yet directly been shown: energy is transferred from hydrogen ions to plasma waves, and then from the waves to helium...

Slowdown of North Atlantic circulation caused sudden cold spells lasting hundreds of years

A new study from the University of Helsinki in Finland reports that sudden cold spells lasting hundreds of years took place in the middle of the warm Eemian climate period, about 120 000 years ago, as a result of the slowdown of the North Atlantic circulation....

Study: How Sun influences lightning and thunder activity on Earth

Japanese researchers have taken the first steps to understand how the Sun's rotational cycle influences lightning activity on Earth. The answers were found in diaries dating back to the 1700s. "It is well known that long-term - centennial to...

Study helps explain why jet stream stalls out over regions, causing extreme weather events

A new study published recently in Science offers an explanation for a mysterious and sometimes deadly weather pattern in which the jet stream stalls out over a region. The discovery is expected to help predict long-term patterns, including which areas may see more...

Study of Earth's magnetic field reversals reveals 405 000-year climate cycle

Gravitational tugs from Jupiter and Venus slightly elongate Earth's orbit every 405 000 years, an amazingly consistent pattern that has influenced our planet's climate for at least 215 million years. This pattern allows scientists to more precisely date...

Rossby waves discovered on and inside the Sun

Scientists have discovered planetary waves of vorticity on and inside the Sun similar to those that significantly influence weather on Earth. Rossby waves are a natural phenomenon in the atmospheres and oceans of planets that form in response to the rotation of the...

Our star is rotating on a helical orbit while spiraling up and down (spiral oscillation)

According to my understanding, all structures in the Universe, including the largest one, are magnetically ordered and centrally powered. The Milky Way follows this standard cosmic model. The astronomical objects and celestial bodies of our galaxy are connected to...

Natural cycles: A link between formation of supercontinents and strength of ocean tides

A new study suggests there is a likely link between the cyclic strengthening and weakening of ocean tides over tens of millions of years and another, longer cycle - the formation of Earth's supercontinents every 400 to 600 million years. The new research...

Solar tornadoes not rotating after all, study shows

According to a team of European scientists, solar tornadoes are not rotating after all. Their new analysis of these gigantic structures, each one several times the size of the Earth, indicates that they may have been misnamed because scientists have so far only been...
