Why do Mediterranean main currents surrounding landmasses turn counter-clockwise?
At North Hemisphere, main superficial currents turn clock-wise, because of Coriolis Effect.
I would expect on Mediterranean Sea to have currents turning in the same sense, but, surrounding landmasses,...

Relationship between obliquity, antarctic circumpolar current, and atmospheric $\ce{CO2}$
Hannah's text on the biology of climate change appears to suggest that forcing due to changes in obliquity can act in opposite ways in Antarctic waters. On one hand,
"Low obliquity brings cool ...

What would the climate be like on an Earth-like planet if it had only one convection cell per hemisphere?
Earth has three convection cells per hemisphere. These are the Polar cell, Ferrel cell and Hadley cell. These create the trade winds, westerlies and polar easterlies which control many aspects of ...

Stream function on a periodic domain?
Part 1
In this paper the authors calculate the barotropic stream function from an output of a numerical model as:
$$\psi(x,y)=\int_0^y\int_{-H}^0u(x,y',z)~dz~dy'$$
over a global domain and this is ...

Why an inertial gyro has a frequency and a geostrophic gyro does not?
Inertial flow is given by the balance between Coriolis and centrifugal forces. A geostrophic flow is given by a balance between Coriolis and the gradients of pressure. The frequency of the inertial ...

Do U & V vectors differ depending on GRIB layers (wind vs current)?
Essentially I would like to know how current direction "DIR C" and wind direction "WDIR" for gribs is computed.
I'm trying to compute some angles from u and v vectors in grib files. My understanding ...

Is there a formula to calculate shoreline length or water position from ocean?
Assuming in the past the water of the oceans were lower does it also mean that the water was not where it is right now?
If yes, then how do we calculate approximately where the water would have been ...
