Sentences with phrase «changes in the wind strength»

Sporadic changes in the wind strength or the rate the companion star strips the main star's hydrogen envelope might also explain the clumpy structure and gaps seen farther out in the disk.

While their graceful flying tactic might saves the albatross energy during flight, the upshot is that any changes in wind strength or direction can have a big impact.

The cooling of the sea between 1948 and warming thereafter are entirely accounted for in the shift in the mass of the atmosphere that lies behind the change in wind strength and the flux in ozone that causes the cloud cover to change.

Not exact matches

Gross says that the most important processes affecting day length are changes in the weather, especially unusual variations in the strength and direction of the winds, which bring on alterations in the global circulation of the atmosphere and ocean.

Importantly, the NAO relates to changes in the strength and position of the North Atlantic jet stream - a band of very fast winds high in the atmosphere.

Already he has shown, at least on the computer screen, that small changes in wind and air temperature — in fact, no more than 3 to 5 degrees — could have redirected hurricane Iniki away from landfall in 1992 and reduced the strength of hurricane Andrew that same year.

Linsley said the new results were «exciting,» suggesting that the «poorly understood, rapid rise» in surface temperature from 1910 to 1940 was, in part, «related to changes in trade wind strength and heat release from the upper water column» of the Pacific Ocean.

The interaction of the ocean and atmosphere means that these changes in sea surface temperatures are translated into changes in wind direction and strength.

Frequent changes in current strength, visibility and water temperature can be expected during the day, except when winds come from the north or northwest.

Wind speed is a useful measure of storm strength (cat 1 - 5, (E) F scale...), and pressure drop also (~ wind speed * distance scale ~ speed * sqrt (area) if not too elongated)-- although (I think) potential energy ~ area * (change in p ^ 2) and kinetic energy ~ area * speed ^ 2 (assumes same vertical extent, densityWind speed is a useful measure of storm strength (cat 1 - 5, (E) F scale...), and pressure drop also (~ wind speed * distance scale ~ speed * sqrt (area) if not too elongated)-- although (I think) potential energy ~ area * (change in p ^ 2) and kinetic energy ~ area * speed ^ 2 (assumes same vertical extent, densitywind speed * distance scale ~ speed * sqrt (area) if not too elongated)-- although (I think) potential energy ~ area * (change in p ^ 2) and kinetic energy ~ area * speed ^ 2 (assumes same vertical extent, density...)

A further potential climate change connection, which Kevin overlooks, is the impact of a warmer world on the strength of the prevailing winds, and their increase in strength with height.

However, the Trade Winds are primarily caused by the Hadley circulation, and are only modulated by the Walker circulation, so it is more precise to think of this result as indicating a change in strength of the Walker circulation.

However, the strength of the winds was much more powerful than expected due to the changes in Pacific sea surface temperature.

Hurricanes, for example, should tend to increase in strength as seas become warmer2 but we also expect that changes in wind shear3 (the change in wind direction with height) should cause a reduction in hurricane frequency4.

Solar» activity» encompasses changes in solar magnetic field strength, IMF, CRF, TSI, EUV, solar wind density and velocity, CMEs, proton events etc..

The physical effects are seen in changes of rainfall, cloudiness, wind - strength and temperature, which are customarily lumped together in the misleading phrase «global warming».

The future evolution of ENSO will be determined by the strength of the South Pacific gyre — that in turn is driven by surface pressure at the South Pole and resultant changes in circumpolar westerly winds.

«The authors write that «the El Niño - Southern Oscillation (ENSO) is a naturally occurring fluctuation,» whereby «on a timescale of two to seven years, the eastern equatorial Pacific climate varies between anomalously cold (La Niña) and warm (El Niño) conditions,» and that «these swings in temperature are accompanied by changes in the structure of the subsurface ocean, variability in the strength of the equatorial easterly trade winds, shifts in the position of atmospheric convection, and global teleconnection patterns associated with these changes that lead to variations in rainfall and weather patterns in many parts of the world,» which end up affecting «ecosystems, agriculture, freshwater supplies, hurricanes and other severe weather events worldwide.»»

States that several interlinked processes have been suggested as contributing to the warming, including stratospheric ozone depletion, local sea - ice loss, an increase in westerly winds, and changes in the strength and location of low — high - latitude atmospheric teleconnections

This basin - wide change in the Atlantic climate (both warming and cooling) induces a basin - scale sea surface temperature seesaw with the Pacific Ocean, which in turn modifies the position of the Walker circulation (the language by which the tropical basins communicate) and the strength of the Pacific trade winds.

On a regional scale, these parameters strongly impact on weather and climate in Europe, determining precipitation patterns and strengths, as well as changes in temperature and wind patterns.

Several interlinked processes have been suggested as contributing to the warming, including stratospheric ozone depletion, local sea - ice loss, an increase in westerly winds, and changes in the strength and location of low — high - latitude atmospheric teleconnections.

In concert with the results for increased extremes of intense precipitation, even if the wind strength of storms in a future climate did not change, there would be an increase in extreme rainfall intensitIn concert with the results for increased extremes of intense precipitation, even if the wind strength of storms in a future climate did not change, there would be an increase in extreme rainfall intensitin a future climate did not change, there would be an increase in extreme rainfall intensitin extreme rainfall intensity.

«A significant change in the strength of the AMOC would alter winds, temperatures and precipitation patterns around the globe, with potentially strong local effects along the east coast of the United States and the west coast of northern European countries,» he said.
