Sentences with phrase «increased wave amplitude»

Two effects are identified that each contribute to a slower eastward progression of Rossby waves in the upper - level flow: 1) weakened zonal winds, and 2) increased wave amplitude.

It interconnects the Atlantic, Pacific and Indian oceans, and provide an uninterrupted stretch for the prevailing westerly winds to significantly increase wave amplitudes.

Not exact matches

Sustained by gravity, they are long ocean waves that increase in amplitude (the tsunamis become larger) as water depth decreases.

«You see three separate waves of cases which have increased in amplitude» that probably reflect reimportations from the other two countries, he said at the press conference.

By scrutinizing its shape just before the final cataclysm, the scientists found that it closely approximated a simple sine wave with a steadily increasing frequency and amplitude.

Phase resetting produces greater alignment of waves across trials and thus greater amplitude in the averaged waveform.9 We then calculated the percentage increase in theta - phase resetting for the 5 - second period after the onset of stimulation, as compared with the 5 - second period before the onset of stimulation.

The increasing amplitude and frequency of the waves during the merger if converted to audio sound waves would make a sound like a chirp of a bird, so the LIGO scientists refer to it as the chirp of a black hole merger.

During NREM sleep, the frequency of the brain waves slows further, whereas the amplitude continues to increase.

Increases in the R - wave amplitude were seen in 154 dogs.

The Screen and Simmonds (2013) paper cited in the letter actually shows some evidence of this effect, as they find a decrease in vertical wave amplitudes (Az in the paper) while the meridional (north - south) waves (Am) are increasing, albeit not statistically significantly.

QRA can be regarded as an extension of the Haurwitz - type mechanism (42) of a strong increase in the amplitude of the midlatitude atmospheric barotropic wave system response to stationary external barotropic thermal forcing, with a spatial frequency m approaching the natural stationary spatial frequency k of the wave system, to the case of external barotropic thermal and orographic forcing under a latitude - dependent u ¯ and an integer m over the midlatitude belt on the spherical Earth.

The possibility of such extremes increase because as the world cools the amplitude of the Rossby Waves increases.

The paper also adds important theoretical support to the research published in 2012 by Dr. Jennifer Francis of Rutgers University, which found that the amplitude of Earth's planetary waves had increased by over 100 miles (161 km) in summer over the past decade in the Northern Hemisphere.

On a related note, there has been a considerable amount of recent interest focused upon a possible increase in the frequency and / or intensity of high - amplitude atmospheric wave patterns (and associated extreme weather events) due to enhanced warming of the Arctic over the past 2 - 3 decades.

The three winter scenarios outlined correspond roughly to a north - south displacement of the stationary wave pattern, to an increase in amplitude of the pattern, and to a shift in phase of the pattern.
