What exactly is a model grid?

A model is a simplified representation of a system. Rather than try to model everything down to the microscopic level, or as vectors, we often aggregate phenomena across geographic areas, to simplify ...

Half of Earth with most landmass

You would have to cut somewhere along this circle: The only landmass here is New Zealand, eastern Australia, eastern PNG, western North America and some Pacific islands. I'm pretty sure you can tweak ...

What exactly is a model grid?

Specifically the term the values are archived on 2.5° grid means that the values that are being reported are being saved and are available at that resolution for historical values. The higher ...

What exactly is a model grid?

To add a bit more mathematical conception to the idea of a grid: think about a 2-D grid(X,Y) as a matrix: this matrix represents a solution to the system of equations you are trying to solve at grid ...

Is Challenger Deep really the deepest place in the ocean?

Short answer : yes Challenger Deep was discovered by (and named after) HMS Challenger in 1875. This was the world's first true oceanic scientific voyage. They took a LOT of soundings but compared to ...

A problem of the 2-Layer hydrostatic model

Let's say our goal is to find $\eta$ which is the displacement of the fluid relative to its resting position at $z = H_2$. We find \begin{equation} \begin{split} p_2 - p_1 &= \require{cancel} \...

Can phytoplankton growth be stimulated in oceans to sequester CO2?

Research into the topic has been intermittent for a variety of reasons. Ocean iron fertilization experiments – past, present, and future looking to a future Korean Iron Fertilization Experiment in the ...

Modelling sea levels with gravitational parameters

Starting from scratch and building a "toy model" is unlikely to be successful here, because while you could certainly model Newtonian tides, much of what happens on the continental shelves is tied ...

Ship turning causing calm water

I feel bad answering this one without any research reference, but I can tell you that what you are seeing in the OP's picture is a 'man overboard drill.' In that drill, the objective is to rotate the ...

Half of Earth with most landmass

It's a moot point, and probably varies somewhat according to the state of the tide. Visually, however, the 'pole of maximum ocean' is about half-way between two atolls in the south Pacific: Tautua, 9&...

How to install ESMF and ESMFPy in Ubuntu using gfortran, gcc, python?

Actually, you probably shouldn't install it. If you're comfortable using Linux, then you would be better advised to use the docker container instead, with it already installed. That way your system ...

How large were Mars' ocean tides and to what extent could they keep the oceans mixing and tend to keep salinity uniform? Has this been modeled?

I will attempt a partial answer. A search of Web of Knowledge finds that most of the papers addressing Martian tides either focus on atmospheric tides and their role in Martian weather or what current ...

Is Challenger Deep really the deepest place in the ocean?

All of the deepest locations are in subduction zones/trenches, where one tectonic plate is being dragged under another one. The greater the angle of subduction the greater the potential for depth of a ...

Regional and Relative Sea level

Assessing sea levels is a complicated business, as there are a number of factors which can affect sea level relative to a fixed point on land. For a start, land levels rise and fall; in some places ...

How will global warming affect climate systems like the ENSO or the MJO?

Still undetermined, though a number of papers on the subject suggest global warming will increase the variance in both of the climate systems you mention. They suggest more research and more refined ...
