Sentences with phrase «zonal flow»

Zonal flow refers to the movement of air in a straight line from west to east. It typically occurs in the upper levels of the Earth's atmosphere. In simpler terms, it means that the air is moving horizontally in a mostly straight line. Full definition
The atmospheric zonal flows extend downwards by more than 2,000 kilometres, but not beyond 3,500 kilometres, as is also the case with the jets.
Moreover, we find that the atmospheric zonal flow extends to more than 2,000 kilometres and to less than 3,500 kilometres, making it fully consistent with the constraints obtained independently from the odd gravitational harmonics.
and... 1992: Is the mid-latitude zonal flow absolutely unstable?
Personally after several years of examining the NCDC SRRS NH Analysis of the 250mb data set, it seems that cross zonal flow strengthens when the heat content differential between the equator and pole are greatest.
Thus instead of a strong zonal wind that keeps cold polar air locked in the Arctic, there is a tendency for a less zonal flow and thus more cold air outbreaks to middle latitudes.
Cao, H. & Stevenson, D. J. Zonal flow magnetic field interaction in the semi-conducting region of giant planets.
Insofar as the New Zealand landmass interrupts what would otherwise be a mainly zonal flow, it effectively splits it, such that, in general terms, the water flows in a clockwise direction around the northern half and anticlockwise around the southern half of New Zealand, and the merged flow continues eastward.
How do you create a model that accommodates years with various combinations of zonal flow or meridional flow?
However, the researchers identify a robust signal that consists of a narrowing of the wintertime mid-latitude zonal flow, due to competing influences of Arctic Amplification and upper - level tropical warming on both flanks of the mid-latitude jet stream.
When ion mass is larger, instabilities are reduced and the zonal flow increases, and the loss of heat and particles in the plasma is suppressed.
However, there remain many unclarified aspects regarding the conditions by which turbulence and zonal flows are formed.
According to research to date, there has been found to occur a unique flow structure called «zonal flow» that is formed spontaneously in a turbulent plasma.
Further, we clarified that in the condition in which the instability has weakened, the «zonal flow» becomes stronger and further suppresses the turbulence by grinding large eddies and waves, and eventually improves the confinement of heat and particles.
Zonal flow is also formed in the striped patterns in Jupiter's atmosphere.
Unfortunately, there is actually quite good model agreement on the overall pattern over the East Pacific through the end of the month: the huge ridge over the Eastern Pacific is expected to persist and perhaps grow even more, continuing the extraordinarily dry pattern over California but allowing for occasionally large swings in temperature as a very cold airmass over Canada is occasionally able to spill westward in weak or even slightly retrogressive (east to west) zonal flow.
In a new study published in the Journal of Climate, the Community Earth System Model Large Ensemble (CESM - LENS) of simulations is used to explore how various characteristics of the mid-latitude atmospheric circulation (zonal flow, synoptic blockings, jet stream meanders) evolve along the course of the 21st century under the RCP8.5 scenario of anthropogenic emissions.
For instance, a slowdown of the zonal flow and an increase in waviness is found over North America, while the European sector exhibits a reinforced westerly flow and decreased waviness.
It is shown how such stirring, as represented by a simple stochastic forcing in a barotropic model, leads to a variability in the zonal flow via a variability in the eddy momentum flux convergence and to patterns similar to those observed.
Most of the time, winds in the atmosphere flow from west to east; this is called «zonal flow» and it's responsible for our everyday weather.
