Monsoon 2020: A “Slow” Start in Context

Monsoon 2020: A “Slow” Start in Context

Monsoon precipitation for Arizona and New Mexico is mostly below average (Fig. 1). This is a slower than normal start, but it is early to say much about what this means for the overall monsoon. The distributions of monthly precipitation totals (Fig. 2, top), and monthly percent of normal (Fig. 2, bottom) highlight the variable timing and intensity of monsoon precipitation. They also show how variability in monthly and seasonal totals can shape our perception of the ‘character’ of the monsoon each year.
