Opis:
The motion of water due to surface waves is the most dynamic factor observed in the marine environment. In this review various aspects of the wave modelling of non-linear, steep surface waves and their role in the atmosphere-ocean interaction are discussed. Significant improvements in wave forecasting have been made in the last ten years. This is to a large extent related to substantial progress in the description of wind forcing and other processes, as well as to the more efficient use of satellite observations and assimilation methods. One striking observation is the increasing variety and complexity of models in which more physical processes are implemented, greater precision and resolution achieved and extended ranges of applicability demonstrated. However, in order to evaluate the applicability of particular models, comparison with high quality experimental data, collected in nature or under laboratory conditions, is necessary.

Opis:
The article’s purpose is the multidimensional analysis of the evolution of Australia and India’s maritime policies and their impact on the endeavors to develop their maritime cooperation in the 21st century. Two research questions are to be answered in that connection: what changes and why India and Australia introduced to enhance their maritime security doctrines in the 21st century and why those changes contributed to the more in-depth cooperation in the second decade of the 21st century. The hypothesis based on those questions argues that not only the rise of China but also global processes in maritime affairs - such as the growing number of state and non-state actors, as well as the interdependence between the fields of human activities at sea - pushed the littorals like India and Australia to turn their maritime strength from coastal to oceanic and convinced them too to cooperate. That process was accompanied by the convergence of the security perceptions by both countries (India and Australia) and the mutual understanding of common interests in all the elements of modern maritime security. The Christian Bueger’s matrix serves as an explanatory framework to highlight the dynamics and broader context of the changes in India and Australia’s maritime security doctrines in the 21st century. It provides the conceptual framework for explaining closer cooperation between these two countries. The article analyzes India and Australia’s maritime strategies, focusing on four variables from Bueger’s matrix: national security, economic development, marine environment, and human security. In those dependent variables, particular elements of their activities serving as sub-variables are highlighted: in national security - shaping the seapower; in economic development - Illegal, Unreported, and Unregulated (IUU) fishing; in the marine environment - climate change mitigation; in human security - the fight against piracy and human trafficking. The choice of the mentioned elements is justified by their role in Australia and India’s activities within maritime strategies and their influence on other elements of the maritime security matrix. The article starts with a description of Bueger’s matrix in the context of the evolution of the maritime security concept in international relations. The second part outlines the centrality of the Indian Ocean in Indian and Australian modern military and economic security. The third part explores and explains the roots of Indian maritime security thinking, and the fourth investigates the evolution in Australia’s attitude toward maritime affairs. The final part presents the developments in Indo-Australian bilateral cooperation in the 21st century.

Opis:
The factors influencing the atmosphere-ocean transfer of mass and momentum, as well as incipient wave breaking and the amount of energy dissipated due to breaking, are discussed in detail. In particular, the influence of directional spreading on the statistics of surface wave slopes and the area of the wind- roughened ocean surface is demonstrated. Theoretical analysis and comparison with the available experimental data show that unimodal directional spreading is not able to reproduce the observed ratio of the cross-wind/up-wind mean square slopes. Better agreement is achieved when bimodal directional spreading, consisting of two wrapped-Gaussian distributions, is applied. The bimodal form suggested by Ewans (1998) is used in the paper. Moreover, the formulae developed here show that the increase in the area due to surface waves is rather small for both regular and irregular waves.

Opis:
The beginning of twenty-first century is characterized with important changes in world shipping and exploitation of ocean resources. Three important trends are clearly visible: environment protection, safety and economy. They materialize in important changes in the structure of world fleet where some existing ship types are going to disappear and new ship types emerge. Increasing the size of some ship types is another visible tendency. Stress on environment protection has serious impact on the hydrodynamic characteristics of ships whether with regard to safety zero accident rate is the goal. Important challenges to ship hydrodynamics caused by those tendencies are discussed in the paper.
