The mean precipitation taken over area
with precipitation for any given day can be considered as the wet - day mean precipitation and provides an indicator for the mean precipitation intensity.
In general, researchers found wood frogs were more sensitive to changes in temperature or temperature
interacting with precipitation than to changes in precipitation alone.
Weather: 10 points 2 points for the ideal amount of precipitation, 3 points for the number of days with rain, 1 point for
days with precipitation of any kind, three points for days above 0 °C, and 1 point fro days above 20 °C).
For records such as ice cores, caves, etc the controls on an isotopic time series can vary by region: in the mid to higher latitudes, there's definitely a temperature signal; in the lower latitudes, you see a big «amount effect» associated
with precipitation in moist convection.
December rounded out the year
with a precipitation total of 1.65 inches, 1.42 inch below average, the fourth driest such month on record.
For accumulation season precipitation annual balance was
correlated with precipitation at Diablo Dam and Concrete WA for differing combinations of months and with April 1 SWE at five USDA SNOTEL stations.
The conditions at the Gobi - Altai mountain range are extreme,
with precipitation at the five research sites Batbaatar established there ranging from roughly 50 to 300 millimeters (2 inches to 1 foot) per year.
They also show that rainfall has dropped by as much as 17 percent
compared with the precipitation in Huayin, a town at the foot of the range, and in Xi'an, the closest big city.
To probe Titan's complex chemistry, Webb will investigate the composition of the atmosphere, watch clouds, track hazes, and monitor changes on the surface that
occur with precipitation, geologic activity, or sea shrinkage.
Following a wet December, drier to much drier than normal conditions returned to California, Nevada, and Oregon this month,
with precipitation less than 50 % of normal across large portions of these states.
Correlating ablation at Lyman
Lake with precipitation, maximum, minimum and average temperature, indicates the best correlation coefficient for monthly May ablation is with average daily temperature at 0.74.
It may seem counterintuitive, he said, because «most people associate dust emission with aridity and deserts,
not with precipitation.»
Our analysis included 2,121 weather stations and looked at days
with precipitation from the months that typically see at least 1 inch of snow so we could get a full sense of not just winter, but the snowy shoulder seasons as well.
Now, researchers have linked airborne dust and other particles from as far away as the Sahara and Asian
deserts with the precipitation that falls over California's Sierra Nevada mountains.
Crater lakes are formed in volcanic calderas which fill up
with precipitation more rapidly than they empty via evaporation.
Impacts of warming and elevated CO2 on a semi-arid grassland are non-additive,
shift with precipitation, and reverse over time.
With precipitation likely and temperatures hovering just a few degrees above freezing in the early morning hours, a snowflake or two is not out of the question.
At a global scale, grasslands are generally distributed in regions of low precipitation across a wide range of temperatures,
with precipitation particularly limiting grassland productivity.
This means that a) the models need work (a lot of scientists agree that they don't do
well with precipitation, b) the satellite measurements are wrong (less likely), or c) some of both.
Researchers show that weakened surface ocean circulation
coincides with precipitation during the Little Ice Age and is consistent with little - to - no changes in the larger Atlantic meridional overturning circulation.
For example, in Siberia for the summer season during the years 1936 to 1994 there was a statistically significant decrease in total precipitation of 1.3 % / decade, but the number of days
with precipitation also decreased.
I still have personal
problems with precipitation and fertilization, but freely admit that I am not in a position to judge those issues scientifically.]
The widespread trend of increasing heavy downpours is expected to continue,
with precipitation becoming less frequent but more intense.13, 14,15,16 The patterns of the projected changes of precipitation do not contain the spatial details that characterize observed precipitation, especially in mountainous terrain, because the projections are averages from multiple models and because the effective resolution of global climate models is roughly 100 - 200 miles.
A quick - and - dirty way to explore this possibility using a «trick»
used with precipitation data is to apply a square root transformation to the rejection rates, average these, then reverse transform the average.
Wet - day percentiles are conditionally computed for the subset of wet events (
with precipitation exceeding some threshold, e.g. 1 mm / d for daily precipitation).
