%description
A weather generator to simulate precipitation and temperature for regions
with seasonality. Users input training data containing precipitation,
temperature, and seasonality (up to 26 seasons). Including weather season
as a training variable allows users to explore the effects of potential
changes in season duration as well as average start- and end-time dates
due to phenomena like climate change. Data for training should be a single
time series but can originate from station data, basin averages, grid
cells, etc. Bearup, L., Gangopadhyay, S., & Mikkelson, K. (2021).
