Sentences with phrase «powerful jet stream»

Because the temperature contrast between the frigid Arctic and the milder mid-latitudes is what drives the powerful jet stream winds that guide weather systems, what happens in the Arctic is bound to have some sort of influence on the world's weather.

The maelstrom is centered within the planet's powerful jet stream, which marks out a peculiar, hexagonal weather system large enough to swallow four Earths.

The planet is characterized most often by its powerful jet streams and Great Red Spot (GRS), the biggest and longest - lasting known atmospheric vortex.

Not exact matches

These observations help clarify the origin of the powerful jet of gas streaming from the galaxy's center at a high fraction of the speed of light: it is likely driven by the swirling matter near the black hole's boundary.»

Saturn's storms are, surprisingly, more powerful than Jupiter's, and its supersonic jet streams are much faster.

The disappearing act could affect far - away weather patterns, as changes at the sea surface affect air currents that steer powerful weather - makers such as the jet stream.

The jet stream — a powerful river of wind high in the atmosphere — shapes the Northern Hemisphere's weather, including bitter cold snaps.

Yet, like dropping a powerful rock in the atmospheric «pond,» climate forcing from greenhouse gases can provoke the jet stream to shift in unexpected ways.

Simple physics dictates that with less sea ice there is magnified warming of the Arctic due to powerful albedo feedback; this in turn reduces the equator to pole temperature gradient which slows the jet stream winds causing them to become more meridional; this combined with 4 % more water vapor in the atmosphere (compared to 3 decades ago) is leading to much more extremes in weather.

Depending on where the powerful winds cross the Atlantic, the jet stream can have a cooling or warming effect on sea surface temperatures in the North Atlantic Ocean, according to the study, published (May 27 2015) in the journal Nature.

Because these waves in the jet stream were so big, Francis says, that pattern became very powerful, which is why it persisted for so long.

The previous suggested reason was that climate change was shifting storms and the powerful air currents known as the jet streams — including the one that traverses the United States — toward the poles, which in turn were driving the movement of the clouds.

The case for a connection between Arctic warming and summertime extreme weather events rests on the Arctic's crucial role as a pacesetter and shapemaker of the jet stream, the powerful ribbon of upper level winds that steer weather systems from west to east across the Northern Hemisphere.

When ocean temperatures climb, powerful new storm tracks and jet streams follow suit, creating a ripple effect of extreme weather felt worldwide.
