Temporal changes in extremely damaging storms

Temporal changes in extremely damaging storms
Records of extremely damaging storms in the United States during the years 1949-2006 were assessed to define their temporal distribution. A change in climate due to global warming may lead to more weather extremes, including storms. The aim
of this study was to learn if the frequency of highly damaging storms had increased. The number of storms at both loss levels has increased dramatically since 1990, and storm-related losses also increased. Much of the increased loss and greater storminess
was due to several recent hurricanes. The AA. speculate about the cause/s of changes in storms and losses : storm measurements and data collection have improved over time; natural variations in climate or a shift in climate due to global warming; society
more vulnerable to storm damages.

Intra-storm attributes of extreme storm events in the Drakensberg, South Africa

Intra-storm attributes of extreme storm events in the Drakensberg, South Africa
Intra-storm rainfall attributes were analyzed for 49 extreme storm events at 5 locations in the KwaZulu-Natal Drakensberg. Three stations located in the mountain foothills and two stations sited on the escarpment edge above 2800 m a.s.l. provide
the first detailed intra-storm data for the Drakensberg. Extreme rainfall events were found to vary in duration and in depth, but all stations measure a clear exponential distribution of cumulative kinetic energy content of storm rainfall over time. Further
research is needed to ascertain the association between storm structure and synoptic conditions, as well as the actual effect that within-storm distribution of rainfall has on runoff and soil detachment.

Hillslope failure and sediment yield in japanese regions with different storm intensity

Hillslope failure and sediment yield in japanese regions with different storm intensity
This paper discusses the effects of storm intensity on the magnitudes of slope failure and sediment yields in Japan. Data were analyzed for 813 river basins that experienced storm-induced failure as well as 30 basins with sediment yield data
. The basins were grouped into 3 categories according to storm intensity to examine the relation between rainfall and erosion magnitudes. Slope-failure magnitudes and sediment yields are also affected by hillslope inclination. The effect of hillslope
inclination is stronger than that of storm intensity.

Storm tides of the Fundy

Storm tides of the Fundy
When a storm tide coincides with an exceptionally high astronomical tide and shallow water depths, the results may be catastrophic. The record of storm tides is knowable, and they may be predictable in the Gulf of Maine-Bay of Fundy region. The AA
. begin with a look at some of the events associated with the most historically memorable Fundy storm tide, the Saxby Tide of 4-5 October 1869.

Profile response of a lacustrine multiple barred nearshore to a sequence of storm events

Profile response of a lacustrine multiple barred nearshore to a sequence of storm events
The aim of this study is to characterize the response of a lacustrine multiple-barred nearshore to a sequence of storm and non-storm events at the intermediate scale. The feedback mechanisms between the pre-existing morphology and the wave forcing
are identified and the consequence of those feedbacks to the behaviour of the nearshore environment over a sequence of storm events is explored at Burley Beach on the southeastern shore of Lake Huron, over the ice-free season of 2001/2002.

The influence of different underlying surface on sand-dust storm in northern China

The influence of different underlying surface on sand-dust storm in northern China
Arid area ; China ; Duricrust ; Dust storm ; Lithology ; Northern China ; Sand ; Surface deposits ; Wind
In this paper, a quantitative research on the relationship between different underlying surface and sand-dust storm has been made by using 40 years meteorological data of 5 different types of underlying surface in northern China, which include
farmland, grassland, sandland, gobi and salt crust. These data comprise sand-dust storm days and strong wind days. The AA. find that there are certain correlations between the days of sand-dust storm and strong wind for different underlying surfaces, which
has great influence on sand-dust storm. There are pronounced differences in different types of underlying surface.

Dust storms evolution in Taklimakan Desert and its correlation with climatic parameters

Dust storms evolution in Taklimakan Desert and its correlation with climatic parameters
Arid area ; China ; Climate ; Climatic data ; Desert ; Dust storm ; Human impact ; Precipitation ; Temperature ; Wind speed ; Xinjiang
Based on the sand dust storms data and climatic data in 12 meteorological stations around sand dust storm originating areas of the Taklimakan Desert, the AA. analyzed the trends of the number of dust storm days from 1960 to 2005 as well
as their correlations with temperature, precipitation, wind speed and the number of days with mean wind speed >5 m/s, to determine the influence of climatic parameters on sand dust storms. The results show that the frequency of dust storm events in the Taklimakan region
decreased with the elapse of time. Climatic factor is one of the major conditions for the occurrence of sand dust storm, but not the only one. The disturbance of human activities will become another important trigger for China's frequent sand dust storms.

Morphological records of storm floods exemplified by the impact of the 1872 Baltic storm on a sandy spit system in south-eastern Denmark

Morphological records of storm floods exemplified by the impact of the 1872 Baltic storm on a sandy spit system in south-eastern Denmark
Coastal environment ; Coastal sedimentation ; Denmark ; Geoarchive ; Inundation ; Natural hazards ; Periodicity ; South-eastern Denmark ; Spit ; Storm
This study investigates the morphological impacts of the 1872 Baltic storm flood on a beach-ridge system (sandy spit) in south-eastern Denmark and evaluates the frequency of extreme storm flood events in the area over a longer time perspective
4500 years of accumulation; the storm flood sediments described are unique suggesting that the 1872 Baltic storm flood event was an extreme event. Thus studies of beach-ridge systems form a new source for understanding storm surge risk.

variations in forest damage. Third, they quantify the level of canopy disturbance in several damage stands. Finally, they compare patterns of damage associated with the 1994 events to those produced by several other ice storms.

Sand dust storms in and around the Ordos Plateau of China as influenced by land use change and desertification

Sand dust storms in and around the Ordos Plateau of China as influenced by land use change and desertification
Aeolian features ; Arid area ; China ; Desertification ; Dust storm ; Inner Mongolia ; Land use ; Shaanxi ; Soil degradation ; Wind erosion
The A. reports a non-linear relationship between sand-dust storm frequency and the index of land degradation which is defined as the percentage of the area of total land that is desertified. Using this non-linear relationship, a threshold
is established which means that sand-dust storm frequency would increase abruptly when the human-induced exceeds 30%. The time series of annual number of sand-dust storm days in the neighbouring area has been compared to the time series in the annual number
