"Precipitation totals" refers to the amount of rain, snow, sleet, or any other form of moisture that has fallen over a specific period of time in a particular area. It tells us how much water has been accumulated from precipitation during a given span, providing insight into the overall weather conditions.
Full definition
Conversely,
precipitation totals at the higher end of the spectrum typically only contribute a small amount to the annual totals.
Specifically, this analysis is of the average of minimum and maximum daily temperature as well
as precipitation totals.
On average, April and May are Boulder's wettest months,
with precipitation totals of 2.45 and 3.04 inches, respectively, between 1948 and 2005, according to the Desert Research Institute.
The state - wide
average precipitation totals for the month of February are as follows: Arkansas averaged 3.09 inches (78.49 mm), Louisiana averaged 2.91 inches (73.91 mm), Mississippi averaged 4.09 inches (103.89 mm), Oklahoma averaged 1.07 inches (27.18 mm), Tennessee averaged 4.29 inches (108.97 mm), and Texas averaged 1.06 inches (26.92 mm).
Despite a near - average
winter precipitation total for California, Oregon, and Washington, the record warmth caused most of the precipitation to fall as rain and not snow, which had implications on the drought intensification and water resource crisis during the warm months.
To the north, in Montana, January is typically one of the drier months of the year with
normal precipitation totals less than 1 in (25 mm).
In that case, a similar slow - moving low pressure system brought moisture from the Gulf of Mexico against the front ranges of the northern Rocky Mountains leading to record
breaking precipitation totals and flooding.
We illustrate the inconsistent relationship between RMSE and MAE by appraising errors associated with the spatial interpolation of
monthly precipitation totals, evaluated over 5 years, at locations across South America (Figure 1).
The number of stations reflecting a locally significant increase in the proportion of total annual precipitation occurring in the upper five percentiles of
daily precipitation totals outweighs the number of stations with significantly decreasing trends by more than 3 to 1 (Figure 2.36 c).
[3] October through December 2016 were very wet months in northern California (with
precipitation totals about 170 percent of normal by 1 January 2017), but because several of the storms were warm rainfall, snow pack in California by 1 January was only 64 percent of normal.
In the western half of the region,
precipitation totals varied from under 5 percent of normal to 70 percent of normal, with most of Texas and Oklahoma receiving less than half the expected precipitation.
The models also projected an increase in intensity of the ARs, meaning an AR impacting the UK in the future is projected to deliver more moisture, potentially causing
larger precipitation totals.
Since 1999, abnormally
low precipitation totals and hot and dry conditions have brought reservoir water levels close to record lows.
The coverage of
extreme precipitation totals and warm temperatures contributed to the fourth highest U.S. Climate Extremes Index in the 106 - year record for the CONUS.
Elsewhere,
precipitation totals ranged between 70 to 90 percent of normal, except for in western Tennessee, where most stations reported values that were near normal to slightly above normal.
Precipitation totals there varied from near normal to 200 percent of normal, however, most stations reported between 130 to 150 percent of normal.
Most stations in the central portion of the region, (including southeastern Texas, northern Louisiana and southern Arkansas)
reported precipitation totals that varied from 50 to 70 percent of normal.
The 60 - station network contained data for 12 meteorological variables and information on the station histories, but the 205 - station network contained mean temperatures and
precipitation totals only, without station histories.
Nationally, the components that measure extremes in warm maximum and minimum temperature and one -
day precipitation totals were much above average.
The Alaska
winter precipitation total was 7.85 inches, 0.30 inch below average, and ranked near the median value in the 1925 - 2015 record.
Northern and western parts of Alaska had near - average
annual precipitation totals, while the eastern and central parts of the state were wetter and much wetter than average.
The statewide
average precipitation totals for the month are as follows: Arkansas recorded 2.59 inches (65.79 mm), Louisiana recorded 5.48 inches (139.19 mm), Mississippi recorded 5.94 inches (150.88 mm), Oklahoma recorded 0.42 inches (10.67 mm), Tennessee recorded 4.65 inches (118.11 mm), and Texas recorded 0.70 inches (17.78 mm).
They first estimated the chances of Harvey's
precipitation total at the present day then estimated the amount of precipitation that would have fallen in an event of the same rarity using 1950s greenhouse gas levels, essentially stripping away the effects of today's higher greenhouse levels.
The March -
May precipitation total for the contiguous U.S. was 9.40 inches, 1.46 inches above the 20th century average.
October through December 2016 were very wet months in northern California (with
precipitation totals about 170 % of normal by 1 January 2017), but because several of the storms were warm rainfall, snow pack in California by 1 January was only 64 % of normal.
