  • History of strong winds in the Czech lands : causes, fluctuations, impacts
  • Climatology ; Czech Republic ; Global change ; Impact ; Sixteenth Century ; Storm ; Tornado ; Twentieth Century ; Wind ; Wind speed
  • Problems of wind speed measurements are analysed. The climatology of strong winds in the Czech Republic during the period 1961-1990 is presented. The main groups of strong winds are characterised according to their origin. The accuracy of historical
  • written reports of strong winds and to their impacts in the pre-instrumental period are discussed. The chronology of strong damaging winds in the Czech lands from A.D. 1500-1929 is presented with a division into gales on the one hand and strong winds
  • connected with convective storms on the other. Cases of gales of the century are described. The impact of strong winds is discussed, with special attention being paid to forest damage.

  • Spatial distribution of wind erosion and its driving factors in China
  • Aeolian features ; Arid area ; China ; Desertification ; Geographical information system ; Land use ; Remote sensing ; Spatial distribution ; Vegetation index ; Wind erosion ; Wind speed
  • Based on remote sensing and geographic information system, the spatial distribution of nation-wide wind erosion is studied, and the 1:100 000 national map of soil erosion by wind in China is made. Wind speed, soil dryness, NDVI, soil texture
  • and the slope of land surface are the key factors to wind erosion. The relations between wind erosion and each factor are discussed. The method of principal component is used to pick up the information included in the 5 factors, and the wind erosion dynamic
  • index (WEDI) is established. Its comparison with the RS/GIS derived data shows that WEDI can reflect the potential capacity of soil erosion by wind.

  • Aeolian deposit ; Aeolian dust ; Aeolian features ; Belgium ; Concept ; Experimentation ; Flanders ; Leuven ; Model ; Wind erosion ; Wind speed
  • This article presents a simple physical concept of aeolian dust accumulation, based on the behaviour of the subprocesses of dust deposition and dust erosion. A model is tested in a series of wind tunnel experiments. Some implications of the model

  • Water circulation induced by the wind in the inner part of a Galician ría (NW Spain) : winter and spring situations
  • Coastal zone ; Estuaries ; Europe ; Sea circulation ; Spain ; Wind effect ; Wind field
  • The wind effect on water circulation was described by means of hydrodynamical measurements carried out in the Ría de Pontevedra (NW of Spain) from February to July 1998. The samples were measured at an anchored station situated in the inner part
  • of the ría. It was observed a clear predominance of wind in the main estuary axis direction. Wind speeds higher than 4 m.s-1 are able to dominate the current at surface layers. Easterly winds force water to leave the estuary at surface layers while westerly
  • winds force water to enter it.

  • Crust strength : a wind tunnel study of the effect of impact by saltating particles on cohesive soil surfaces
  • Aeolian features ; Aeolian transport ; Duricrust ; Experimentation ; Soil ; Soil properties ; Wind erosion
  • A wind tunnel study examined the effect of distributions of saltating particles on sediment surfaces which were characterized by distributions of their tensile strength. The sediments consisted of varying proportions of large sand-sized particles

  • Effects of spatial variations in source areas upon dust concentration profiles during three wind erosion events in Australia
  • Aeolian features ; Aeolian transport ; Arid area ; Australia ; Dust storm ; Erodibility ; Floodplain ; Model ; Queensland ; Spatial variation ; Wind erosion
  • Dust storms are a major contributor to soil erosion in inland Australia, and the Simpson Desert-Channel Country region is one of the most active wind erosion regions. While information is available on wind erosion rates at the land-type level

  • Climatological classification of severe wind-driven rain events affecting the southern United States
  • This paper follows recent studies of wind-driven rain (WDR), and statistically defines a severe WDR event. The research suggests a classification for severe WDR events by association with larger scale weather systems. The study incorporates data

  • Air temperature ; Bulgaria ; Mountain ; Poland ; Radiation ; Relief ; Slope exposure ; Tatra Mountains ; Temperature gradient ; Thermal regime ; Wind speed
  • The paper presents the solar radiation, air temperature, temperature gradient and wind velocity in two different mountain ridges : high Tatras and Vitosha. It points out the role of relief, the land cover or exposure in forming thermal conditions
  • . Glacial relief and alpine character of Tatras determine the solar and thermal features stronger than the older, lower,mountains e.g. Vitosha. On both Tatras and Vitosha the temperature gradient seems to be most dependent on wind velocity. - (BJ)

  • This paper reports on a series of portable wind tunnel tests conducted on a system of clay-crusted playas along the Bouse Wash, near Desert Wells, Arizona, to examine the importance of saltation abrasion in the emission of PM10 (particulate matter

  • Aeolian dust ; Aeolian features ; Agricultural practice ; Agropedology ; Cultivated land ; Germany ; Grain size distribution ; Niedersachsen ; Organic materials ; Seasonal variability ; Soil erosion ; Wind erosion
  • The dynamics of fine aeolian dust emitted from agricultural land was investigated over 15 months near Grönheim, Lower Saxony. This study was unsertaken in the framework of WEELS (Wind Erosion on European Light Soils), an international EU project
  • focusing on wind erosion in northern Europe. Dust activity in Grönheim is high in spring and autumn, and low to very low during the rest of the year. There is a strong relationship between the periods of tillage and the intensity of dust activity.
