Sentences with phrase «by atmospheric waves»

These storms are typically sparked by atmospheric waves traveling all the way from the coast of Africa, and generally don't appear until later in the hurricane season.

Because the breakdown of the stratospheric polar vortex is driven by atmospheric waves, which are related to short - term weather fluctuations, we can't forecast these events more than 10 - 15 days in advance with much skill.

Not exact matches

Sweltering summertime heat waves are on the rise across the Northern Hemisphere because of atmospheric changes brought on by Arctic warming, new research shows.

The best way to explain this spike is from the swirling maelstrom below, where turbulent atmospheric waves must generate heat by crashing together like breakers on a windy beach shore.

Other than in previous publications, optical rogue waves in this system are clearly ruled by atmospheric turbulence in a gas cell, effectively enabling the observation of a storm in a test tube.

Along the East Coast, where the «green wave» of spring leaves sprouting from maples, oaks and poplars historically has rolled from Miami to Maine in 75 days, atmospheric scientists with Princeton University predict the wave could take just 59 days by the end of the century.

The new research solves this mystery by connecting the atmospheric waves to vibrations of the Ross Ice Shelf — the largest ice shelf in the world with an area of almost half a million square kilometers (188,000 miles), roughly the size of France.

«If atmospheric waves are generated by ice vibrations, by rhythmic vibrations of ice — then that carries a lot of information of the ice shelf itself,» said Oleg Godin, a professor at the Naval Postgraduate School in Monterey, California, and lead author of the new study, published in the Journal of Geophysical Research: Space Physics, a journal of the American Geophysical Union.

The two examples shown here are small waves — atmospheric circulation is driven by large - scale waves, with wavelengths that are hundreds or thousands of kilometers.

Naturally, scientists wanted to see if they could see any movement on these lakes, as it could tell them more about atmospheric dynamics — particularly the winds, because waves are caused by winds transferring their kinetic energy into the liquid.

The recurring wave pattern of intense rain and thunderstorms, followed by a dry phase as the force moves across the cooler Pacific Ocean occurs every 30 - 60 days, giving this atmospheric wave its unique stamp on the climate.

By using simulation modeling, the researchers found that the heat wave was the result of abnormal atmospheric patterns

In the tropical Pacific, the distance from Indonesia to South America and the way tropical winds push warm water west combine to allow special waves to travel along the equator and are amplified by the atmospheric wind response to produce large fluctuations in temperatures (up to 3 degrees Celsius) in the Eastern Pacific that last for months.

Provoked by both the quake and the tsunami, these atmospheric gravity waves traveled over and to the west of Japan, while the tsunami was stopped by the coast.

The work is an estimate of the global average based on a single - column, time - average model of the atmosphere and surface (with some approximations — e.g. the surface is not truly a perfect blackbody in the LW (long - wave) portion of the spectrum (the wavelengths dominated by terrestrial / atmospheric emission, as opposed to SW radiation, dominated by solar radiation), but it can give you a pretty good idea of things (fig 1 shows a spectrum of radiation to space); there is also some comparison to actual measurements.

The natural process of atmospheric blocking, and the climate impacts induced by such blocking, are the principal cause for this heat wave.

Recognition has grown in the scientific community that droughts, heat - waves and other catastrophic weather and climate events are not random in occurrence, nor are they caused only by variations in remote ocean temperatures altering large - scale atmospheric circulation.

That is an incredible bit of hand - waving there, and completely contradicted by the basic math — atmospheric concentration increase has been less than our emissions for about the last 60 + years, meaning nature is acting as a net sink over that period.

Forests can affect the global climate system by altering large - scale patterns in atmospheric waves and jet streams, a mechanism termed «teleconnection patterns» (e.g., [12, 15 — 19]-RRB-.

In September last year, following an unusually low measurement of Arctic sea - ice extent, Damian Carrington wrote: «Ice is the white flag being waved by our planet, under fire from the atmospheric attack being mounted by humanity.»

As I have pointed out previously on spiked, when one out of six new studies showed that a new record had been set for Arctic sea ice extent, the Guardian's Damian Carrington declared: «Ice is the white flag being waved by our planet, under fire from the atmospheric attack being mounted by humanity.»

He showed that atmospheric absorption of long - wave radiation was constant for 61 years while at the same time carbon dioxide increased by 21.6 percent.

This very unusual atmospheric configuration — in which the large - scale atmospheric wave pattern appears to be largely «stuck» in place — has been characterized by a seemingly ever - present West Coast ridge and a similarly stubborn trough over central and eastern United States (commonly referred to in media coverage as the «Polar Vortex,» though this terminology is arguably problematic).

By using an idealized heating to force a comprehensive atmospheric model, the large negative anomalous latent heating associated with the observed deficit in central tropical Pacific rainfall is shown to be mainly responsible for the global quasi-stationary waves in the upper troposphere.

In the tropical Pacific, the distance from Indonesia to South America and the way tropical winds push warm water west combine to allow special waves to travel along the equator and are amplified by the atmospheric wind response to produce large fluctuations in temperatures (up to 3 degrees Celsius) in the Eastern Pacific that last for months.

All that is needed is to add heat carried upwards past the denser atmosphere (and most CO2) by convection and the latent heat from water changing state (the majority of heat transport to the tropopause), the albedo effects of clouds, the inability of long wave «downwelling» (the blue balls) to warm water that makes up 2 / 3rds of the Earth's surface, and that due to huge differences in enthalpy dry air takes far less energy to warm than humid air so temperature is not a measure of atmospheric heat content.

«Ice is the white flag being waved by our planet, under fire from the atmospheric attack being mounted by humanity.

Wang et al. (2014) find that tropical West Pacific SST warm anomalies (associated with the West Pacific Warm Pool that acts as a precursor of El Niño) played a leading role in causing the strength and longevity of the Triple R by generating a recurring series of atmospheric «Rossby waves» that propagated from west to east across the Pacific Basin.

ENSO is of course not a sloshing but at the very least a binary system involving atmospheric circulation in the central Pacific and Kelvin and Rossby waves — all stochastically forced by wind, pressure and current fields.

For example, it is said that the Moscow heat wave was caused by an extreme atmospheric «blocking» situation, or the Texas heat wave was caused by La Niña ocean temperature patterns,» the researchers write.

Stable and accurate solutions to the Navier Stokes equations for large scale atmospheric flows are obtained by filtering sound waves (the hydrostatic assumption) and filtering high frequency unresolved gravity waves.
