Sentences with phrase «turbulent motions in»

«With CH +, we learn that energy is stored within vast galaxy - sized winds and ends up as turbulent motions in previously unseen reservoirs of cold gas surrounding the galaxy,» said Falgarone, who is lead author of the new paper.

It has long been suspected that turbulent motions in the lower solar atmosphere are propagated outward as waves in some form, which ultimately shock the thin atmosphere above the surface (the photosphere).

Wouter Bos at the École Centrale de Lyon in France and his colleagues have now tracked a turbulent fluid's motion by picking one point and following it as the fluid tosses it about.

«The high resolution allowed us, for the first time, to ensure that small - scale turbulent disk motions are accurately captured in our models,» Tchekhovskoy said.

Using further 3 - D dynamo simulations, which model the generation of magnetic field by turbulent fluid motions, Driscoll looked more carefully at the expected changes in the magnetic field over this period.

Figure 02: The «Moment 1» panel shows the change of velocity across the galaxy, indicating a smooth rotation, while «Moment 2» gives the spectral line's width, here showing a broad line toward the turbulent star - forming nuclear bar and more ordered motion in the arms themselves.

Since CH + forms exclusively in small areas where turbulent motions of gas dissipates, its detection in essence traces energy on a galactic scale.

Professor Giles Harrison, who led an international research team including scientists from the University of Reading's Meteorology department, the Met Office and the European Centre for Medium Range Weather Forecasting, said: «The sky is often full of clues to weather changes, and asperitas provides distinctive visualisation of complex and turbulent air motions in the lower atmosphere.»

«This (non-isothermal isentropic profile) indeed brings us to the broader framework discussed by Maxwell, in the sense that convective turbulent motions are now taken into account, albeit implicitly....

Yet making progress is challenging, in part because their dynamics involve three - dimensional, turbulent fluid motions on the scale of a few meters, the nonlinear interaction of turbulence with the formation of cloud droplets, and the interaction of these cloud droplets with radiation (e.g. Wood (2012)-RRB-.

The narratives decribing parameterizations in papers discussing climate models themselves don't seem to suggest LES like parameterization, as the parameterization does not depend on the computational grid size of the length scale of the turbulent like motions.
