There will be more winter and spring precipitation in the northern U.S. and less winter and spring precipitation in the southwest U.S. Moreover there will be severe agricultural drought conditions across most of the country by 2070 and much longer dry seasons in the southern part of the country.
The results indicate that: (1) winter and spring precipitation processes at most stations are nonstationary, while summer and autumn precipitation processes at few of the stations are stationary.
In the United States, this is expected to bring more winter and spring precipitation in the northeast, and increases in the frequency and intensity of extreme precipitation everywhere.
Precipitation during spring and autumn were statistically significantly associated with annual mortality (spring precipitation RR 0.982, CI 0.965 1.000, p=0.048; autumn precipitation RR 1.018, CI 1.004 1.032, p=0.01, per centimetre increase of precipitation).
For all three varieties, fall temperatures seem to be of higher importance in the first 50 years (0.1>p>0.05), whereas summer temperatures and spring precipitation have no apparent influence.
This might explain the lack of association between spring precipitation and mortality in the last period (1825 1859).
In the inland lineage, 59 loci were identified as significantly correlated, including 17 loci for spring precipitation, and 21 loci for summer precipitation.
Compared to the Mongolian summer pasture, higher water availability due to higher amounts of snow melt water and spring precipitation were likely to foster plant growth on the Chinese summer pasture during the late spring, the period immediately preceding summer pasture utilization.
The latter also impacts the dispersion of precipitation changes; and (4) the seasonal model is appropriate for modeling spring precipitation, but the global model performs better for summer, autumn, and winter precipitation.
In comparison, different changing properties of summer precipitation were detected when compared to spring precipitation changes.
Currently, above average spring precipitation has left some alfalfa stands suffering this spring.
