This IPython notebook demonstrates how to calculate and plot the mixing percentage of the three major water masses from the South Atlantic.

The data used is freely available, and consist of temperature and salinity downloaded from the "World Ocean Atlas 2009".

The mixing percentage of each water mass is obtained ...

Todos os notebooks mostrados nesse site e utilizados em aula exigem uma série de módulos Python que podem ser complicados de instalar. Para facilitar as aulas onde utilizo esses notebooks criei uma Máquina Virtual (VM) em OVF ...

Here is a quick example on how to create a kmzfile with image overlays using matplotlib and simplekml.

The make_kml() function below is just a wrapper around simplekml. It takes as arguments:

• A list of matplotlib figures;
• The figure(s) LatLon box (all overlays must have the same bbox);
• An ...

This post is part of the Introduction to Geophysical Fluid Dynamics, 2nd Edition post series on converting the MatlabTM examples to python. Chapter 3 contains just one mfile with an implementation for the Equation of State-80 (Chapter 3.3 -- Equation of State.)

But before we go any further it is ...

As soon as classes return from a "forced" holiday (AKA Carnaval), I indent to show my Weather and Climate students some database sources to create the figures they need for their homework.

Here I'll show two simple examples: wind from scatterometer (Quickscat*) and wind Stress from the Hellerman and ...

Second part of the chapter on Coriolis from Introduction to Geophysical Fluid Dynamics, 2nd Edition

Here I implemented mfiles parabolic.m (script that calls the animation) and coriolisanim.m (a function for the animation)

The animation shows the trajectory of a particle on a parapoloid in absolute axes and the ...

Another post for my Introduction to Dynamical Oceanography class using the MatlabTM numerical exercises from Introduction to Geophysical Fluid Dynamics, 2nd Edition

This time I implemented two mfiles coriolisdis.m (discretization of inertial oscillation) and numcorio.m (a function need by the former) both from chapter two (Coriolis). Again I ...

Starting next week I'll be teaching a new class (Introduction to Dynamical Oceanography). I'll be using the Introduction to Geophysical Fluid Dynamics, 2nd Edition book by Cushman-Roisin & Beckers. This book has an interesting approach where all the topics are shown from an analytical and numerical point of view ...

This post will be a short and simple one. I could not prepare anything more elaborated for this week because I was out on a much deserved holiday.

It is a quick example on how to use sympy, to evaluate and plot functions.

Let's start!

The cell bellow activates ...

I'm slowly replacing all the figures from my class slides with either an open version available online, or a version of my own. So far it has been easier than I thought! Here are one from my Descriptive Oceanography course and another from my Waves and Tides course.
