WindNinja Tutorials

</html> ##[WindNinja Has Moved, Click here to view the latest tutorials](https://weather.firelab.org/windninja/tutorials/) WindNinja is a computer program that computes spatially varying wind fields for wildland fire applications. It is specifically designed to simulate the mechanical and thermal effects of the local terrain on the wind. Unlike traditional weather models, WindNinja does not predict wind for future times (it does not step forward in time), rather it simulates the spatial variation of wind for one instant in time. # These tutorials provide basic instruction on the main features of WindNinja. * * *

Tutorial 1:The Basics This tutorial provides a step by step guide to running a basic WindNinja simulation.

Tutorial 2: Diurnal Winds and Non-neutral Stability This tutorial will step you through the process of running a WindNinja simulation that includes diurnal slope winds and an atmospheric stability that is not neutral.

Tutorial 3: Point Initialization This tutorial will step you through the process of running a WindNinja simulation that is initialized by location specific wind information. Note that the point initialization option is not currently available for use with the momentum solver.

Tutorial 4: Weather Model Initialization This tutorial will step you through the process of running a WindNinja simulation that is initialized by output from a weather forecast model. Note that the weather model initialization option is not currently available for use with the momentum solver.

CLI Instructions This guide explains how to run WindNinja from a command line.
