  • Trends in fog frequency and duration in the southeast United States
  • Atmospheric moisture ; Climatic trend ; Fog ; Forecast ; Linear regression ; Southern United States ; United States of America ; Virginia
  • This study identifies the trends and frequency of fog events across the south-eastern United States. A simple linear regression was performed on hourly datasets for annual and seasonal fog-event days and on fog duration. The majority of Virginia
  • stations displayed significant decreasing numbers of fog-event days for 3 seasons, and 4 stations experienced decreasing fog events in all fog-duration categories.
  • Fog : a possible solution to rural water problems ?
  • Countryside ; Fog ; Fresh water ; Project ; South Africa ; Water ; Water needs ; Water resources
  • Acute water shortages are experienced regularly in many areas. It is thus of the greatest importance to identify other sources of water in these regions. Fog is one such new source of fresh water and shows a significant potential for use
  • as a domestic water supply, notably the South African Fog Water Project. - (AJC)

  • The disappearance of dense fog in Los Angeles : another urban impact
  • Atmospheric moisture ; Atmospheric pollution ; California ; Climatic trend ; Fog ; Heat island ; Los Angeles ; Ocean atmosphere interaction ; Twentieth Century ; United States of America ; Urban climate
  • This study looks at 50 years of dense fog data for coastal Los Angeles and attempts to explain its downward trend. Both the downtown Los Angeles urban heat island and the city's air pollution clean up show a significant relationship to decreasing
  • fog. The A. correlates monthly and annual dense fog data recorded at Los Angeles International and Long Beach International airports since the 1950s with downstream los Angeles temperature and particulate air pollution data. The El Niñ-Southern

  • The AA. present an initial study to project the long-term development of fog occurrence along the southern African west coast. For this purpose, they implemented a basic fog diagnostic scheme based on liquid water content into the regional climate
  • model REMO. Regarding the long-term development of fog, two 20-year time slice simulations for a control (1981 to 2000) and a future (2081 to 2100) period following the A1B emission scenario were conducted. The model generally projects a slight increase
  • in the number of fog days for the coastal areas and a slight decrease for the regions located further inland. Especially the latter has the potential to exacerbate the existing water scarcity in the region.

  • Altitude ; Carpathian Mountains ; Climatology ; Fog ; Interannual variability ; Mountain ; Orographic effect ; Poland ; Pollution ; Spatial distribution ; Wind
  • The aim of this study is to give a general description of fog frequency, as well as to indicate the potential role of pollutant deposition via fog in the environmental processes ongoing in the Carpathians. The annual number of days with fog (NDF
  • The roles of salt (sodium nitrate) and fog in weathering : a laboratory simulation of conditions in the northern Atacam Desert, Chile

  • availability and 3 levels of fog precipitation. The experiment took place over an 11-week period. Collectively, the results indicate that fog appears to control the rate of breakdown and that salt availability controls the timing of the response. The style
  • of breakdown was similar, irrespective of the fog and salt levels. The morphological observations provide an experimental example of the role of inheritance in weathering processes.
  • Some characteristics of cold air lakes and fog in the Jinghong and Mengyang basins, Xishuangbanna, China
  • The main point of these studies are to discover the temperature distributions between the south-facing and north-facing slopes and clarify the temperature distributions on the slopes at night-time with and without fog.
  • Meteorological patterns and fog water collection in Morocco and the Canary Islands
  • Fog - boon or bane ?
  • Canary Islands ; Comparative study ; Fog ; Morocco ; Rural community ; Seasonality ; Water resources ; Weather type
  • The aim of this study is to characterize the synoptic weather patterns that justify fog water collection on the coast of Morocco and the Canary Islands. Furthermore, fog water collection is studied to evaluate its feasibility as a sustainable water
  • resource to satisfy the drinking water needs of a rural population in SW Morocco. The study period was from 2006 to 2010. Standard Fog Collectors (SFC) and the Quarter Fog Collectors (QFC) that were connected to automatic meteorological stations with which
  • hourly and daily data can be recorded were used. The average quantities of collected water were about 10 l/m2/day at both sites, but there is inverse seasonality since more fog water is collected in Morocco in the winter whereas in the Canary Islands

  • An inland mountainous location in eastern Spain was selected for reforestation studies based on the fog water collection potential prevailing in the area and the high level of land degradation. Bulk fog-water catches were stored and used in a micro
  • -irrigation network to provide summer emergency water pulses to a plot of reforestation seedlings. Fog collection measurements during the 3-year period of the experiment revealed an average water yield, which, although moderate, is a suitable value
