Session ID#: 15960

Session Description:
Geophysical fields display complex structures over wide ranges of scales, Symmetries and their breaking possibly, but not necessarily, spontaneous can therefore play a major role like in physics to uncover some hidden simplicity like (statistical) scale invariance. The latter have been initially sought in conjunction with several other symmetries of the underlying equations, such as translation, rotational and mirror symmetries. However, forcings, the gravity field and rotation of the Earth may easily break these symmetries, while preserving others like scaling. Significant examples are the breaking of isotropy and translation invariance in boundary layers, convection, precipitations and floods, the breaking of the mirror symmetry in geophysical fluid dynamics and the corresponding generation of helicity that plays a key role in hurricane dynamics or solar flares.

In this session we welcome contributions on obtained results and developed techniques of data analysis and modeling on symmetries from across the various domains of geophysics.
