Examining the relationship between snowfall and wildfire patterns in the western United States
Applied climatology ; Correlation ; Forest fire ; Snow ; Snow cover ; United States of America ; Western United States
The AA. conducted an examination of the spatial and temporal relationships and correlations between snow cover and wildfire from 1986 through 1996 in the 11 westernstates of the United States. Snow-cover and wildfire data were aggregated
and normalized for each state, as well as for the entire western region. No strong correlation was found for the entire western United States, nor did state aggregations show signs of consistent yearly correlation between measures of snow cover and wildfire
. Nevertheless, a few states experienced above-average acreage burned totals following winters with above-average snow cover.

If judged on the basis of profit, the projects initiated by the Western Nigerian Development Corporation have failed. But there are other objectives such as combatting unemployment, conserving foreign exchange or continuing unprofitable transport
services for social reasons. Public entreprises should, therefore, be run on business lines but supported if necessary by the state. (EMS).

This paper examines modern climate analogues of the western United States for 18,000 and 9000 yr B.P. in order to explain patterns of spatial heterogeneity. The study area of this paper includes the United States west of 93°W in order to cover
Holocene rock varnish microstratigraphy and its chronometric application in the drylands of western USA
Arid area ; Climatic variability ; Correlation ; Dating ; Desert ; Holocene ; Lithology ; Micromorphology ; Quaternary ; United States of America ; Western United States
Analyses of hundreds of rock varnish samples from latest Pleistocene and Holocene geomorphic features in the drylands of western USA reveal a regionally replicable Holocene microlamination sequence. This radiometrically calibrated and climatically
correlated Holocene microlamination sequence was then used as a unique correlative dating tool to determine surface exposure ages of geomorphic and geoarchaeological features in western USA deserts. The results indicate that, when properly applied
, the varnish microlamination dating technique has the great potential to yield numerical age assignments for surface stone tools, petroglyphs, and geoglyphs of prehistoric age in the drylands of western USA.
Brazilian county-level juridical documents as sources for historical geography: a case study from western São Paulo state
Land survey and subdivision records, probate cases, land-tenure litigation and labor complaints were used to reconstruct vegetation and land use in western São Paulo state in the twentieth century. - (DWG)
Comparison of soils in midwestern United States and western Europe with the interglacial record
Western Europe and midwestern United States are best explained by relatively long interglaciations or the development of composite soils over a number of temperate periods. Climatic contrasts between the interglaciations appear to have been overemphasized

The effect of urban pull on a declining agricultural man-power is studied in detail in three villages in Western Nigeria. If the trend is to be altered rural industries and socio-economic infrastructures must be improved. (EMS).

Since a millenary the Czech State has been figuring in different territorial extent and a differant degree of dependence on the political map of Central Europe. The Czech national individuality is territorially still based especially on the Czech
