By looking beyond the single archaeological site and instead focusing on settlement patterns, regions, and the surrounding landscape archaeologists are able to look at large - scale spatial and temporal patterns of social organization, land use, and their environmental impact.
Vertical motion and spatial extent of 2 of the largest regions are confirmed by satellite image differencing.
Although it is well established that the Sun's magnetic field is responsible for the supply of energy to the atmosphere, exactly how this magnetic energy is converted into thermal energy is still not understood in detail, as models struggle to simultaneously encompass the very disparate temporal and spatial scales on which the heating has to occur, in different structures, with a wide variety of characteristics (e.g. open versus closed structures, short quiet - sun loops versus hot active - region loops and large - scale interconnecting loops).
Abstract Accurate quantification of the spatial distribution of precipitation in mountain regions is crucial for assessments of water resources and for the understanding of high - altitude hydrology, yet it is one of the largest unknowns due to the lack of [continue reading...]
These subcontinental spatial units can be chosen to coincide not only with regions of high observational density but also with spatial domains defined by large - scale climate features.
The GCMs don't yet have enough spatial resolution to handle multiple major climatic transitions in small areas, but the models are presently accurate enough to draw conclusions for large climatic regions like «the desert Southwest,» or «the Great Plains,» «the Indian subcontinent,» or «the African savanna.»
Even with the generally large spatial coherence and correlation length scales of temperature anomalies at polar latitudes (e.g. Hansen et al. 1999; Chapman and Walsh 2007), none of the reconstruction methods can escape the basic limitation of few in situ observations in West Antarctica, and all exhibit less skill in this region compared with other regions of the continent.
Recent studies reinforce the large role of emissions from tropical regions in influencing the observed spatial concentration gradients.
This suggests to me that you're getting spatial smearing from other regions with larger warming trends.
A slowly evolving change in the circulation may thus lead to seemingly abrupt changes in precipitation in regions where the existing spatial gradients in rainfall are largest.
The text below discusses the evidence for: (1) abrupt changes in the circulation and (2) steady changes in the circulation that may, in turn, trigger relatively abrupt changes in climate in regions of large spatial gradients in surface weather.
The spatial distribution of the altimeter sea level trends during 1993 - 2017 shows large - scale variations, with some regions such as the western tropical Pacific Ocean experiencing up to +8 mm / year.
These range from simple averaging of regional data and scaling of the resulting series so that its mean and standard deviation match those of the observed record over some period of overlap (Jones et al., 1998; Crowley and Lowery, 2000), to complex climate field reconstruction, where large - scale modes of spatial climate variability are linked to patterns of variability in the proxy network via a multivariate transfer function that explicitly provides estimates of the spatio - temporal changes in past temperatures, and from which large - scale average temperature changes are derived by averaging the climate estimates across the required region (Mann et al., 1998; Rutherford et al., 2003, 2005).
Aggregate population growth, as well as redistribution of the population across larger US regions, strongly affects outcomes whereas smaller - scale spatial patterns of population change have smaller effects.
Vertical motion and spatial extent of 2 of the largest regions are confirmed by satellite image differencing.
