The phrase "average precipitation rate" is correct and usable in written English.
It can be used in contexts related to weather, climate studies, or environmental science when discussing the typical amount of precipitation over a specific period.
Example: "The average precipitation rate in this region has increased over the past decade, indicating a shift in climate patterns."
Alternatives: "mean rainfall rate" or "typical precipitation level.".
Average precipitation rates of the four sites differ from 110 to 250 mm/year.
Although average precipitation rates are high compared to other parts of the world, water is scarce due to extremely shallow soils with a low capacity to retain water, unimodal rain patterns, and privatization of the few quality water sources that exist [ 5].
This idealized study allows to isolate the representativeness error and to derive statistical adjustments for the along-track averaged precipitation rates with respect to the area-averaged precipitation rates to minimize the representativeness error.
The provided data represent the average daily precipitation rate calculated in 1/10 mm.

For the statistical analysis the total hourly number of road incidents from 28 May to 3 June 2013 was combined with the average daily precipitation rate.
The region receives a bimodal rain fall, the average annual precipitation rate being 1000 that comes from the long and short rainy seasons.
Figure 3 provides an overview of the case study's temporal patterns by combining a red scatter plot of the number of road incidents per hour with grey box plots of the average daily precipitation rate in the time period from 28 May to 3 June 2013.
> -wrap-foot> The correlation coefficients between the general patterns of each phenological phase according to life-forms and community type, and the average monthly precipitation rates, are given in Table 3.
Spearman rank order correlations were calculated between average monthly precipitation rates, recorded over 26 years in the meteorological station at Kavanayén (Ramírez et al. 1988), and the frequency of species in flower and with unripe and ripe fruit in the different life-forms and community types, respectively.
