What I’ve Been Listening To – January 2016

February 1, 2016

And so, like a flash, the first month of 2016 has come and gone. The weather is really beginning to ramp up now and hit the UK with its full, highly dynamic glory. Thanks to this abysmal serving of rain, clouds and somewhat lacklustre cold snaps, I’ve had plenty of time sat at my computer...

Modeling Atmospheres with the Unified Model

February 24, 2015

In my last couple of posts I’ve been going through some of the basic principles of fluid mechanics. From some of the basic approximations that make the equation possible to analytically solve in this post, to some more specialised theory in the context of planetary systems in this post. In these posts we’ve been slowly...

The Fluid Mechanics of Planetary Atmospheres

February 16, 2015

In my last post I went over a really powerful bit of physics called fluid mechanics, which describes the flow of fluid through a system. The main equation in this framework is the momentum equation; the Navier-Stokes equation.This equation is nye on impossible to solve analytically in it’s full grotesque glory, so in the last post I discussed some of...

Radiative Transfer in Planetary Atmospheres: An Overview

January 1, 2015

A little while ago I got carried away on a little post which discussed a really cool little bit of physics called radiative transfer. As I said then, radiative transfer is a technique that you can use to study how energy, in the form of electromagnetic radiation, moves through material. In that post, which you can...

Gambling with Statistics – Monte Carlo Methods

July 20, 2013

Hey all! In my recent work I’ve been using numerical simulations involving radiative transfer, which basically  means transferring energy via radiation such as light; in the form of photon packets. The way these simulations are run is via a method known quite widely in the physics world called ‘Monte Carlo Methods’. It took me a...
