HWMAID

This repository contains two Python codes:

• hwmid: to evaluate the intensity and duration of heatwaves from daily gridded maximum temperature
• hwens: to calculate mean, std and probability from the results of hwmid

Dependencies

An Anaconda environment with all the required dependencies can be created using environment.yml:

conda env create -f environment.yml

To activate the environment, use:

conda activate hwmaid

The installation time of the required dependencies should not exceed 3 minutes using a stable and standard internet connection

Usage

hwmid takes 4 input files:

• analysis_file: the daily gridded maximum temperature to be analyzed
• per90_file: the multi-year daily running 90th percentile of the reference data
• t25_file: the 25th percentile values over all year max of the reference data
• t75_file: the 75th percentile values over all year max of the reference data

usage: hwmid.py [-h] [-d NDAYS_TMAX] [-o OUTDIR] [-p NPROCS] [--outfile1 OUTFILE1] [--outfile2 OUTFILE2] [--outfile3 OUTFILE3] [-t TIMERANGE] [-s SHOW_PBARS] analysis_file per90_file t25_file t75_file

Process heat wave index data.

                        Comma speparated indices of the processesfor which progress bars have to be shown

hwens takes 3 types of input files:

• the duration files created by hwmidfor all members
