Peru’s 12-Month Rain and Snowfall Totals
Thanks to meteorologist John Hart for a U.S. Geological Survey (USGS) accepted precipitation report for the period October 1, 2018 – September 30, 2019. Measurements were taken on the Jabez Allen Road, 4.1 miles east, southeast of the hamlet’s center; other locations may differ a little, or a lot! click here to view in a pdf, more readable format.
John Hart explained the report in more detail.
What is the US Geological Survey(USGS) Water Year? A water year (also called hydrological year, discharge year or flow year) is a term commonly used in hydrology to describe a time period of 12 months for which precipitation totals are measured. Its beginning differs from the calendar year because part of the precipitation that falls in late autumn and winter often accumulates as snow and does not drain until the following spring or summer’s snowmelt.
The USGS Water Year is the 12-month period that most consistently, year after year, gives the highest correlation between precipitation and streamflow and negligible changes in storage (i.e., soil water and snow). The water year is designated by the calendar year in which it ends, so the 2019 water year (USGS) started on October 1, 2018 and ended on September 30, 2019.
