divided into three parts: turbulent momentum flux τ t , WC momentum flux τ w , and viscous momentum flux τ υ . Viscous momentum flux is important only in the lowest millimeters of the atmospheric boundary layer ( Smedman et al. 2003 ) and is neglected in this study. The ratio of the WC momentum flux to the total momentum flux decays with height, as indicated by measurements and numerical simulations ( Sullivan et al. 2008 ; Högström et al. 2015 ). Under growing wave conditions, the WC momentum

-level wind fields in the intertropical convergence zone (ITCZ) are strongly influenced by convectively coupled propagating waves on synoptic time scales (e.g., Tai and Ogura 1987 ; Lau and Lau 1990 ; Gu and Zhang 2002 ; Roundy and Frank 2004 ; Serra et al. 2008 ), with the dominant synoptic atmospheric disturbances westward-propagating Pacific easterly waves (PEWs; Chang 1970 ; Reed and Recker 1971 ; Nitta et al. 1985 ; Tai and Ogura 1987 ; Lau and Lau 1990 ; Gu and Zhang 2002 ; Serra and

multivariate sea states for nearshore wave climate characterization ( Camus et al. 2011a ). Other examples of clustering application can be found in Izaguirre et al. (2012) where by means of the self-organizing maps algorithm, the authors relate extreme wave height anomalies in the NA with certain identified atmospheric situations. A few studies assessing spectral wave climate variability have been found in the literature, basically because spectral buoy records are not long enough to cover an entire

the ocean wave model WAM ( WAMDI Group 1988 ; Komen et al. 1994, hereinafter referred to as WAM4 ). In this formulation the surface stress (and hence the drag coefficient and the surface roughness length) depends on the sea state. The implication is that in the marine atmospheric boundary layer wind-generated ocean waves may play an important role on the evolution of mesoscale and synoptic-scale weather systems, through the modulation of the surface fluxes of momentum, heat, and moisture

1. Introduction In Part I of this study ( Desjardins et al. 2000 , hereinafter referred to as DML), the impact on the atmosphere of two-way coupling of a mesoscale atmospheric model and the wave model WAM was investigated and described. The results of tests on four storm cases showed that the impacts were small in terms of the evolution of the storm itself, but that locally large impacts on some of the surface parameters were noted. In Part II we investigate and describe the impact of the

1. Introduction: The two-way coupling between the atmosphere and the ocean wave field This numerical study analyzes the evolution of a low pressure system over the sea and of the resulting oceanic wave field in the presence of a two-way coupling between the atmospheric and ocean wave models. Usually, it is assumed that there is a one-way coupling between the atmosphere and the surface waves without any feedback from the ocean waves generated by the surface wind on the atmospheric circulation

-scale, atmospheric, Rossby–Haurwitz wave and the signals from the propagated CTWs forced by remote synoptic weather systems. In this study, we separate the two processes from PIESs P bot data by using data of several tide gauges, and we give some quantified results. The rest of the paper is organized as follows: Section 2 describes the data used for this study and processing methods. Section 3 demonstrates cross-spectral analysis results providing the evidence for Rossby–Haurwitz waves and CTWs. Section 4

, global model to pressure fields representative of the Rossby–Haurwitz atmospheric wave. Besides trying to establish if the observed ζ signals are indeed related to the Rossby–Haurwitz forcing wave, we examine the conditions under which a dynamic response is expected and the extent to which excitation of near-resonances is part of the dynamics. To introduce the numerical solutions, we first use the LTE formalism to discuss what is expected theoretically for a flat-bottom ocean covering the globe
