It is suggested that the seasonal dependence of interannual variability displayed by observed sea surface temperature (SST) over the north tropical Atlantic primarily reflects the seasonality of the remote forcing associated with the North Atlantic and Southern Oscillations and is controlled by the mean damping time scale of SST anomaly. A stochastic model including a seasonally dependent forcing is used to test this hypothesis against observations. © 2004 American Meteorological Society.

Czaja A, 2003, On the time variability of the net ocean-to-atmosphere heat flux in midlatitudes with application to the North Atlantic basin, Quarterly Journal of the Royal Meteorological Society, Vol: 129, Pages: 2867-2878, ISSN: 0035-9009
A new diagnostic to investigate the role of ocean dynamics in midlatitude air-sea interactions is presented and tested against observations. It is based on the analysis of the time variability of the net ocean-to-atmosphere heat flux (FS). A hierarchy of air-sea interaction models indicate that, in the absence of ocean dynamics, the power spectrum of FS should be blue at time-scales longer than a threshold set by the late-winter mean mixed-layer thickness and the sensitivity of FS to sea surface temperature anomalies. Comparison of the predicted FS spectrum with observations over the North Atlantic shows a good agreement over the subpolar gyre where the deep ocean mixed layer combined with strong stochastic forcing allows large fluctuations in FS at decadal and longer time-scales. Discrepancies, however, arise over the Gulf Stream extension region. Here it is suggested that the observed variability of FS at time-scales longer than a decade is controlled by geostrophic ocean dynamics rather than local atmospheric forcing. The diagnostic appears to be a useful and simple tool to investigate the role of ocean dynamics in the upper-ocean heat budget. It is particularly well suited to the analysis of long simulations of coupled ocean-atmosphere models. One implication of the study for ocean-only numerical simulations is that one cannot specify externally the low-frequency variability of FS. The latter should only arise as a consequence of ocean dynamics.

Czaja A, Robertson AW, Huck T, 2003, The role of atlantic ocean-atmosphere coupling in affecting North Atlantic oscillation variability, Geophysical Monograph Series, Pages: 147-172, ISBN: 9780875909943
We review the role of ocean-atmosphere interactions over the Atlantic sector in North Atlantic Oscillation (NAO) variability. The emphasis is on physical mechanisms, which are illustrated in simple models and analyzed in observations and numerical models. Some directions of research are proposed to better assess the relevance of Atlantic air-sea interactions to observed and simulated NAO variability.
