Anyone could give me some hints in Tangential Geostrophy? Websites, papers, anything...
Cheers!

Tangential geostrophy is a principle in oceanography and atmospheric science that describes the balance between the Coriolis force and the pressure gradient force. It is used to explain the movement of fluids in the Earth's rotating frame of reference, such as ocean currents and atmospheric winds.
Hints are commonly used in tangential geostrophy to help calculate the velocity of fluid motion. These hints can come from observations, such as measurements of pressure and temperature, or from theoretical assumptions and simplifications of the governing equations.
Some examples of tangential geostrophic flows include the Gulf Stream in the Atlantic Ocean, the Kuroshio Current in the Pacific Ocean, and the jet streams in the Earth's atmosphere. These are all large-scale, persistent flows that are partially driven by tangential geostrophy.
The Earth's rotation plays a crucial role in the principle of tangential geostrophy. It creates the Coriolis force, which is a result of the changing velocity of a fluid in a rotating frame of reference. This force is crucial in balancing the pressure gradient force and maintaining the balance of tangential geostrophy.
While tangential geostrophy is a useful principle for understanding large-scale fluid motions, it does have some limitations. It assumes that the fluid is in a steady state and that all forces are in balance. In reality, there may be other factors at play, such as turbulence and friction, that can affect the fluid motion. Additionally, tangential geostrophy is most accurate for large-scale flows and may not accurately describe smaller-scale motions.
