  • Synoptic weather types : an index of evaporation in southern Louisiana
  • Climatologie synoptique ; Etats-Unis ; Evaporation ; Géographie physique ; Indice climatique ; Louisiana ; Type de temps
  • Synoptic weather types have been found to be useful tools in the study of various environmental processes. One viable use of synoptic weather types is the determination of regional estimates of evaporation. In southern Louisiana, rates of mean daily
  • pan evaporation by synoptic weather types are useful as an index of evaporation, based on the frequency of weather type occurrence.

  • Deep weathering in Sweden
  • In Sweden the following types of deep-weathering can be distinguished : complete formation of kaolinite, less complete chemical weathering, granular weathering, and fracturing into angular blocks. It is suggested that weathering is of greater
  • The influence of two epilithic lichens on the weathering of quartzite and gabbro
  • Biogenic action;Biogenic process ; Crystalline rocks ; Vegetation ; Weathering
  • Evidence is presented suggesting that micro-vegetation, notably lichens, substantially influences the weathering of the material on which it grows. Changes on two rock types are examined in order to assess the role of lichens in the mechanical

  • A quantitative survey of the impact of the weather on the activities of the building and construction industry in South Africa is presented. The industry has no sophisticated response to varying weather conditions and recommendations are made

  • Weathering in the Wyborg rapakivi area, south-eastern Finland
  • the weathering to be of preglacial origin. The rapakivi saprolites are of grus type. The weathering has caused both mechanical and chemical alteration of the parent rock. The residual topography comprises small tor-like features.
  • Field survey of weathering sites in the Wyborg rapakivi area indicates that saprolites are far more common in the central part of the massif than in the marginal areas. Many till-covered saprolites and parautochthonous crust-tills prove
  • A synoptic weather type analysis of january hourly precipitation at Lake Charles, Louisiana
  • Circulation atmosphérique ; Climatologie ; Climatologie synoptique ; El Nino ; Etats-Unis ; Géographie physique ; Hiver ; Louisiana ; Oscillation climatique ; Précipitation ; Type de temps
  • Each measurable hourly precipitation event during january at Lake Charles, over the 1951-80 period has been classified by associated synoptic weather type. Using Muller's synoptic classification, four types were found to produce rainfall over
  • the study period. The frontal-related weather types increased dramatically during the colder months, and also increased in association with El Nino events and related cyclogenesis in the western Gulf of Mexico.

  • In this paper, sky view and weather controls on nocturnal surface moisture deposition are explored using data collected in Vancouver, British Columbia, Canada, during the summers of 1993 and 1996. The study focuses on residential (suburban) areas
  • : residential lawns and grassed parks. Moisture accumulation at open sites was strongly controlled by weather conditions. Correlation was seen between moisture accumulation and wind and cloud conditions expressed as the semi-empirical weather factor.

  • In order to represent the weather distribution of Japan related to the winter monsoon, the modified method of Jacob's synoptic climatology was adopted. Airflow patterns were decided for each of five regions in Japan. - (SGA)
  • The characteristics and significance of deep weathering in the Gaick area, Grampian Highlands, Scotland
  • The Gaick area is a landscape of selective linear glacial erosion. Deep weathering of Moine psammites occurs on preglacial slopes but is absent from glacially-overdeepened valleys. The weathering is of gruss type and its thickness, together
  • with the importance of halloysite in the clay fraction, indicates that the weathering predates the middle Quaternary ice sheet glaciations. The weathering demonstrates very limited erosion of the preglacial slopes and owes its preservation in part to the development

  • the exposing of the nunatak, but the other types of weathering have not actively advanced in recent times. Sheeting has precipitated rock falls, and has gradually formed a gray mosaic on the varnished wall. The sheeting was caused by gravitational body force
  • The weathering of granodiorite porphyry is examined in the extremely cold and dry environment of the inland part of Antarctica. Weathering features include granular disintegration, rock varnish, and sheeting. Sheeting has gradually proceeded since
  • Ecological perspectives on rock surface weathering: towards a conceptuual model
  • Biogenic process ; Concept ; Ecology ; Lichen ; Lithology ; Micro-organism ; Model ; Weathering
  • A wide range of information is now available on the ecology of rock surface microorganisms and lichens and their role in weathering in particular locations. External environmental conditions as well as rock characteristics determine the type of rock
  • surface community, and thus the style of biological weathering. A simple, preliminary conceptual model can be drawn, which relates biological weathering activity to an environmental stress gradient and which is applicable at a range of scales.
  • Ten years (1994-2004) of potential weathering in Kärkevagge, Swedish Lapland
  • Cold area ; Comparative study ; Granite ; Lapland ; Limestone ; Plant canopy ; Soil properties ; Sweden ; Weathering
  • This paper reports the findings of a ten-year study of potential weathering of machine-polished dolomite, granite and limestone discs buried in shallow pits beneath a variety of vegetation cover types in Kärkevagge and on an adjoining ridge
  • in Swedish Lapland. In general, dolomite was the most useful material for monitoring mass loss, with limestone weathering tending to be too rapid and granite weathering being too slow.
