Forty-one years of data from 13 first-order National Weather Service stations in the southeasternUnitedStates were analyzed to determine the spatial variability in the frequency and duration of hours and days when temperatures were ≥32°C (high
Temporal trends in annual Palmer's Drought Severity Index (PDSI) for 53 climate divisions are examined for the period 1895 to 1988 in the southeasternUnitedStates, including Alabama, Florida, Georgia, Mississippi, North Carolina, South Carolina
Climatology of tropical cyclone rainfall in the southeasternUnitedStates
Climatology ; Hurricane ; Observation network ; Precipitation ; Soil moisture ; Tropical cyclone ; UnitedStates of America ; Water balance
Rainfall associated with tropical cyclones contibutes a significant amount to the annual rainfall in the southeasternUnitedStates. This study quantifies this amount from 1980-2004 and aims to determine the contribution of tropical cyclone-induced
The primary purpose of this study is to examine the spatial evolution of meteorological drought severity within the contiguous UnitedStates during the first six months of an average drought event. Drought events occurring during the period January

; Tennessee ; Texas ; UnitedStates of America ; Weather type
This paper examines the synoptic climatology and seasonality of heavy rainfall across the southeasternUnitedStates, in adopting a threshold approach. Frontal systems (particularly cold fronts) were found to be the dominant mechanism that induces
Climate, lightning, and wildfire in the national forests of the southeasternUnitedStates : 1989-1998
Atmospheric electricity ; Climatic index ; Drought ; Forest ; Forest fire ; Model ; Natural hazards ; UnitedStates of America ; Years 1990-99
The AA. compiled the record of wildfires from each national forest unit in the southeasternUnitedStates for the period 1989 to 1998, then regressed annual fire numbers against lightning flash densities and measures of climatic drought (seasonal
Transport direction of Wisconsinan loess in southeastern Minnesota
Aeolian features ; Glacial features ; Grain size distribution ; Loess ; Minnesota ; Quaternary ; Sediment transport ; Sedimentology ; Stratigraphy ; UnitedStates
A study of Wisconsinan loess in part of southeastern Minnesota confirms earlier suggestions that much of the loess in this region was not derived from the floodplain of the Missisippi River. Two Wisconsinan loess units, the Peoria Loess and Roxana
A synoptic climatology of extreme unseasonable floods in the southeasternUnitedStates, 1950-1990
Climatic event ; Flood ; Hurricane ; Natural hazards ; Rainstorm ; Seasonality ; Synoptic climatology ; UnitedStates of America ; Weather type
The purpose of this study is to identify the synoptic atmospheric environment associated with extreme unseasonable flood events in the southeasternUnitedStates. Unseasonable is defined as flood occurrence in the season of lowest flood frequency
Twentieth-century precipitation variability and directional vegetation change in southeastern Arizona
Annual variation ; Arizona ; Climatology ; Drought ; Global change ; Moisture ; Potential evapotranspiration ; Precipitation ; Rocky Mountains ; Twentieth Century ; UnitedStates of America ; Vegetation
Studying a century of rainfall records, the AA. find no conclusive evidence that periods of precipitation abundance or deficiency could have been responsible for vegetation change in southeastern Arizona during that period. - (DWG)
Petaloid organs preserved in an arctic plant macrofossil assemblage from full-glacial sediments in southeastern Minnesota
Flora ; Glacial features ; Minnesota ; Palaeo-environment ; Palynology ; Pleistocene ; Pollen analysis ; Quaternary ; Tundra ; UnitedStates of America
This paper reports on a small arctic flora from full-glacial sediments exposed in the Jore-1 site in southeastern Minnesota, an area not covered by late Wisconsinan ice.
Suspended-sediment transport in an intensively cultivated watershed in southeastern California
California ; Cultivated land ; Irrigation ; Runoff ; Sediment transport ; Soil erosion ; Suspended load ; Turbidity ; UnitedStates of America ; Watershed
The aim of this study is to investigate the variation of sediment movement at multiple spatial and two temporal scales of an agricultural watershed in southeastern California where surface runoff is primarily supplied by irrigation.
Post-Nipissing origin of a backdune complex along the southeastern shore of Lake Michigan
Dating ; Dune ; Geochronology ; Holocene ; Lake ; Michigan ; Palaeogeography ; UnitedStates of America
The coastal dune complex southwest of Holland is fairly typical of the coastal dunes along the southeastern shore of Lake Michigan, consisting of massive parabolic dunes along the shore and smaller backdunes up to 1 km inland. This study tested
Subregionalization of low-frequency summer drought variability in the SoutheasternUnitedStates
Atlantic Ocean ; Atmospheric dynamics ; Climate ; Climatic variability ; Drought ; North Atlantic oscillation ; Ocean atmosphere interaction ; Pacific Ocean ; SoutheasternUnitedStates ; Summer ; Surface temperature ; UnitedStates of America
This article examines the subregionalization of low-frequency summer drought variability in the SoutheasternUnitedStates. It shows that drought variability is significantly associated with ocean-atmosphere variability in the Atlantic and Pacific
basins. The Eastern Gulf States subregion exhibits a long-term increase in summer moisture that is significantly associated with Northern Hemisphere surface temperature increases during the last century. The peninsular Florida subregion is characterized
Western range boundaries of floodplain trees in the southeasternUnitedStates
Biogeography ; Boundary ; Climate ; Coastal plain ; Floodplain ; Habitat ; Riparian vegetation ; SoutheasternUnitedStates ; Spatial distribution ; Tree ; Underground water ; UnitedStates of America
Forest vegetation in the southeasternUnitedStates extends westward beyond the Ozark and Ouachita plateaus in Arkansas and Missouri into the Central Plains. Along this transect, the transition from luxuriant forests to mixed forests and grasslands
