This atlas contains climatological summaries for seven parameters based on modeled data. Included are wind speed and direction, significant wave height, wave direction, wave slope parameter, modal wave period, and directionality of the waves. The last three parameters have not appeared in previous U.S. Navy climatological atlases, because they cannot be directly derived from visual observations. This atlas provides the design, scientific and operational communities with a detailed representation of the overall wave climate of the Mediterranean Sea. Keywords: Ocean waves spectra; Mathematical models; Wind direction; Ocean surface; Marine climatology; Ocean graphic data charts.

This pilot atlas introduces a new, numerically derived, historical data set in the form of a wind and wave climatology. Existing wave climatologies are primarily based on visual ship observations, these climatologies may be unreliable, particularly in data-sparse regions. This atlas provides the design, scientific and operational communities with a detailed representation of the overall wave climate of the whole North Pacific Ocean. Keywords: Spectral Ocean Wave Model (SOWM); Grid; Wind speed and direction; Significant wave height; Primary wave direction; Wave slope parameter; Modal wave period; Directionality of the waves; Isopleth analyses; Contingency; Durations and intervals; Atlas.
