The geostrophic balance is denoted in the form of numbers. Kelvin scale, Rossby waves structures, geostrophic adjustments etc are included. Continuously stratified dynamics: Inertia-gravity waves, potential velocity. The physical oceanography mainly focuses on the describing and to understanding the evolving patterns of marine circulation and fluid motion levels, along with the dispensation of its properties such as temperature range, saltness and the concentration of dissolved chemical constituents and gases evaporation. The ocean as a dynamic fluid is studied at a large range of spatial scales from the centimeter scales are like the turbulent microstructure through the many thousand-kilometer scales of the ocean gyres and the global overturning rotation measurement. Approaches include theory, direct investigation, and computer simulation. The research can frequently take place in the context of an important multidisciplinary problems including the dynamics and predictability of global climate and the sustainability of human use in coastal and estuarine portions.

The diversification of the program in physical state oceanography is rapidly increased by the numerous joint and an affiliate positions with two world-class research laboratories are invited, they the University's Applied Physics Laboratory and with the nearby National Oceanic and Atmospheric Administration Pacific Marine Environmental Laboratory, where many of the graduate students choose to do their research. Together the atmosphere and an ocean have a big and consequential impact on humanity. The combined dynamics of the atmosphere and the ocean are leading contributors to global climate changes. The people live within the climatic conditions and are almost it is helpless affected by the weather and its rather chaotic behavior which modulates an agricultural success. Ocean currents effects the navigation, fisheries living, and pollution disposal. Populations increases that occupy coastlines can do little to prevent the hurricanes, typhoons, or tsunamis.

By the understanding and reliably predicting the geophysical fluid dynamic results and trends are scientific, economic, humanitarian, and even political priorities also. The two features that defined to geophysical fluid dynamics from the other areas of fluid dynamics are the rotational of the earth’s planet and the vertical density stratification of the medium. Geophysical media are in the form of narrowed stratified layers, in which the vertical velocities are much smaller than the horizontal velocities structures. The trajectories of fluid constituents are nearly horizontal while vertical velocities are much smaller than horizontal velocities. This chapter examines several freewave solutions of the shallow-water identifications.
