Is it possible for a sting jet to form over a continental landmass?

Sting jets are thought to be responsible for some of the most damaging winds associated with extratropical cyclones in the mid-latitudes. So far they have only been confirmed in the European region, ...

Forced shallow-water equation with diabatic heating as the source term

How to obtain the divergence of velocity field $\left(\nabla.\mathbf{u}\right)$ with ${Q}$ (something proportional to the diabatic heating rate) as the source term from the thermodynamic equation? ...

Physics based circulation models

How useful are physics based models when considering circulations at synoptic scales? Are they useful? Can we not make predictions, observe trends based on data alone? I am studying A.E.Gill's model ...

Book on atmosphere dynamics

I plan to study a good introductory book on atmospheric dynamics: which one is more recommended? My background is a university degree in physics, but I'm new to meteorology. An Introduction to ...

Initiation of Rossby waves during MJO

I am trying to understand the basic dynamics of MJO, where I find several studies which relate it to the initiation of equatorial Rossby and Kelvin waves. Though MJO is an eastward propagating wave, I ...

For fine particles to get dispersed throughout the globe via atmospheric circulation, in what level of the atmosphere would they have to travel?

For molecular-sized particles to disperse around the entire planet, would they have to reach the stratosphere, or could air currents in the troposphere distribute them? Are particles dispersed ...

Application of vorticity tendency equation

I have a question about the dynamics of westward propagating vortices. In meteorology, the vorticity tendency is often used to explain the westward propagation of vortices (cyclonic circulation). A ...

Internal energy, enthalpy, and work in the atmosphere

I'm writing a toy radiative-convective atmospheric model and need to relate the heat flux convergences (either surface sensible heat flux or the radiative flux) to changes in atmospheric layer ...

Compute upwind flux for gridded data

I'm trying to compute something called the "Drying Ratio" following: Eidhammer, 2018 The drying ratio is the ratio of the precipitation to the incoming vapor flux. So, $DR = \frac{F_{in} - ...

How should one even try to start thinking about quantifying the total emissions footprint for the planet?

I was recently reading a paper in which nine planetary boundaries have been proposed. The paper uses modeling and literature assessment to quantify safe and just Earth system boundaries (ESBs) for ...
