A simple explanation is presented for the observed interannual changes in the dominant space and time scales of Northem Hemisphere winter extratropical high frequency variability. It is found that such changes can suc- cessfully be predicted by linearizing a 2-level quasi-geostrophic mode] in spherical geometry around the ob- served zona] mean states. The mechanisms responsible for the selection of the most unstable normal mode are investigated.

Amplitude Dependency

A density functional theory based method was used to model dynamics of high frequency delocalized normal mode and discrete breathers in graphene at T = 0 K. For the normal mode the comparison of results was made with modeling by means of classical molecular dynamics. Discrete breathers have been found only in presence of uniaxial strain applied in “zigzag” direction. The oscillations of breather core atoms appeared to be polarized along “arm-chair” direction. In the case of “arm-chair” uniaxial strain there were no breathers found. The frequency on the amplitude dependency of DBs in graphene corresponds to the soft nonlinearity type that is due to the soft nonlinearity type of the high frequency normal mode on which breather is constructed.
