This repository contains data and central python codes for Doanet et al., 2022, "Hillslope Roughness Reveals Forest Sensitivity to Extreme Winds". 

Python Codes:
1. Doane2022_ExtremeValueFitResist.py is a python script that iteratively changes the overlap between probability distributions of driving forces and resisting forces. 
2. Doane2022_hourlyGustDist.py is a python script that develops the conditional distribution of strongest 3-second gust and hourly gust speeds. THen It develops the extreme value distribution of gust speeds. 

Data: 
1. MMGust.npy is a numpy array of 3 second gusts over two years.
2. MMhourly.npy is a numpy array of hourly averaged wind speed over these two years. 
3. MorganMonroeWind.zip is hourly averaged wind speed data over 20 years. This mus be unzipped for Doane2022_hourlyGustDist.py to run.
4. varVals.npy is an array of values that are the bin edges for the pdf of topographic variance values
5. pdfZVar.npy is a numpy array of the probability density for topographic roughness values.
