### Modeling swirling storms

I'm looking to demonstrate the rotational behaviour of swirling storms with a numerical simulation. So far it includes pressure-gradient, Coriolis acceleration, frictional forces and the acceleration ...

### What is the equivalent of CFL criterion when using spectral models?

I would like to know what the equivalent of the CFL criterion is for atmospheric models based of spectral grids. In other words, how do you find the necessary horizontal resolution in meters for ...

### Statistical dependence of mean annual soil evaporation and mean annual precipitation globally

I am studying a simple dynamical system that represents a plant and water system, similar to Klausmeier. In Klausmeier model the mean annual precipitation and the soil evaporation are introduced as ...

### Determining rotation of a bending detachment fault system

I would like to obtain the angle of rotation (𝛿θ) of a detachment fault (or oceanic core complex) after X meters of rock displaced during spreading at a mid-ocean ridge. I have a differential ...

### Unwanted oscillations in Synthetic seismogram

I have generated a synthetic seismogram using FDTD elastic velocity-stress formulation on a staggered grid. I can't understand origin of oscillations modulating on seismogram. Is it a result of ...

### Model relating reservoir releases with downstream temperature

Are there any statistical/numerical models developed relating release from reservoirs with the downstream river temperatures? I know of complicated hydrodynamic models such as CE-QUAL-W2 etc. but I am ...

### How to determine the orientation of coastline from NetCDF file

I have a NetCDF file (gridded data) with a landsea mask. I would like to determine, for the coastal grid-cells, what the orientation of the coastline is. I need to do this in order to calculate the ...

### How to control output precision when running WRF?

I am very new in this area and wondering if anyone can answer my following questions: I am running WRF (4.0.3, ideal) to study rounding and truncation. I use the NCL (6.5.0) print command to access ...

### WRF: minimal list of variables required by coupling a land surface model to the whole system

We are trying to couple our land surface model into WRF. As a first step, we'd like to know what is the minimal list of variables required by such coupling?

### Do snow and ice have different temperatures at their interface?

tl;dr: For snow on top of ice, is the temperature at the base of the snowpack always (practically) the same as the temperature at the top of the ice? I was trying to understand how the thermodynamics ...
