Researchers from the University of California Irvine have shown that a phenomenon known as the Atlantic Multidecadal Oscillation (AMO)-- a natural pattern of variation in North Atlantic sea surface temperatures that switches between a positive and negative phase every 60 - 70 years — can affect an atmospheric circulation pattern, known as the North Atlantic Oscillation (NAO), that influences the temperature and precipitation over the Northern Hemisphere in winter.

In addition, global sea level can fluctuate due to climate patterns such as El Niños and La Niñas (the opposing phases of the El Niño Southern Oscillation, or ENSO) which influence ocean temperature and global precipitation patterns.

As discussed in the Climate chapter, large - scale atmospheric circulation patterns connected to changes in sea - surface temperatures strongly influence natural variations in precipitation and temperature (e.g., Cayan et al. 1999; Mantua and Hare 2002).

This is addressed by evaluating change in global or large - scale patterns in the frequency or intensity of extremes (e.g., observed widespread intensification of precipitation extremes attributed to human influence, increase in frequency and intensity of hot extremes) and by event attribution methods.

Water is also strongly influenced by climate, as changes in temperature and precipitation consistently alter patterns of water availability and quality throughout the state.

Wills et al. (2016) present an analysis of how circulation changes influence the global pattern of change in net precipitation (precipitation minus evaporation, P — E).

Global warming will clearly change the temperatures and influence the patterns of precipitation, but it won't make any difference to the available hours of sunlight at any point on the globe.

E. 7.3 Describe how global patterns such as the jet stream and ocean currents influence local weather in measureable terms such as temperature, air pressure, wind direction and speed, and humidity and precipitation.

N (1) Natural mechanisms play well more than a negligible role (as claimed by the IPCC) in the net changes in the climate system, which includes temperature variations, precipitation patterns, weather events, etc., and the influence of increased CO2 concentrations on climatic changes are less pronounced than currently imagined.

The large interannual to decadal hydroclimatic variability in winter precipitation is highly influenced by sea surface temperature (SST) anomalies in the tropical Pacific Ocean and associated changes in large - scale atmospheric circulation patterns [16].

For example, the Climate and Health Assessment found that «rising temperatures, changing precipitation patterns, and a higher frequency of some extreme weather events associated with climate change will influence the distribution, abundance, and prevalence» of some vectors like the mosquitos that carry the West Nile virus.

One last point related to my last post, is the extent / degree of magnitude of a more meridional atmospheric circulation pattern (N.H. especially) could influence snow cover, cloud cover, and precipitation amounts which could set up stronger positive climatic feedbacks, which could then result in an even more significant climatic change going forward.

While Zhang et al. (2007) concluded globally that they had detected an anthropogenic influence on the overall latitudinal patterns of precipitation trends (that is, the climate model trends were of the same sign as the observed trends), in the latitude band that includes the majority of the United States population a mismatch between model projections and precipitation trends was found (Figure 1).

Winter precipitation (mean and extreme) variability and trends along the south coast and interior of Alaska appear to be closely related to variations in the PNA pattern over this timeframe, while El Nino / Southern Oscillation (ENSO) influences, through the Nino3 index, appear to be significant along the south coast alone.

This will help scientists explore, more accurately than is possible today, how rising temperatures, shifting precipitation patterns, increasing greenhouse gas levels, and other natural and human - induced changes affect tropical forests» influence on Earth's climate.
