Abstract
Daily records of atmospheric surface pressure, temperature and geopotential heights of 500 hPa isobaric level were tested for nonlinearity, the necessary condition for deterministic chaos, using redundancy and surrogate data techniques. While the time series of the temperature and the geopotential heights were found indiscernible to be from correspondent isospectral linear stochastic processes, a significant nonlinear component was detected in the dynamics of the pressure recording, however, no specific signatures of low-dimensional chaos were manifest.
