Appalachian Mountains ; Atmospheric circulation ; Atmospheric moisture ; Heavyrain ; Mountain ; Orographic effect ; Precipitation ; Seasonal variation ; United States of America ; Weather type
Synoptic data associated with a sample of 554 heavy rainfall events is utilized to carry out a trajectory analysis that identifies the movements of moisture towards region of heavyrain. Both seasonal and regional variations are found
in the moisture trajectories associated with heavyrain events occurring in three regions in the Appalachian study area.
Torrential rains in central Karakoram, 9-10 September 1992 : geomorphological impacts and implications for climatic change

Descriptions of the effects of rockfalls and mudflows in the Braldu Valley, northern Pakistan, below 3000 m elevation that were triggered by the heavyrains of a late nonsoonal incursion. - (DWG)
their statistical characteristics, mainly including spatial and temporal distributions, variations and climatic trends of the 2 parameters of the durative heavy precipitation events in China.This method can be applied in flood assessment and climate change fields.
Situaciones atmosféricas tipo que provocan aguaceros torrenciales en comarcas del mediterraneo espanol. in Las lluvias catastroficas mediterraneas. (Weather type situations that bring heavyrain in the Mediterranean provinces of Spain)
The effects of heavy winter rains and rare summer rains on biological soil crusts in the Negev Desert
Biological soil crusts (BSCs) abound in the Hallamish dune field in the western Negev Desert, Israel. The aim of this paper is to examine crust responses to winter and summer rains, focusing particularly on its biomass components, chlorophyll
of the BSCs increase 2–3-fold following winter rains; much higher species composition was monitored at the BSC during the winter; summer rain substantially deceased the chlorophyll content of the crusts; summer rains may alter species composition and biomass
Spatial, synoptic, and seasonal patterns of heavy rainfall in the southeastern United States

This paper examines the synoptic climatology and seasonality of heavy rainfall across the southeastern United States, in adopting a threshold approach. Frontal systems (particularly cold fronts) were found to be the dominant mechanism that induces
heavy rainfall across the study area, but tropical disturbances and air-mass storms also contribute, especially at the more coastal locations. Annual regimes were found to vary dramatically from one site to another, and 7 of the 8 sites investigated

Information on extreme rains and floods during the last millennium is gathered on the basis of various records. It is possible to distinguish heavy downpours, continuous rains, rainy seasons, rapid snowmelts and combinations of all of them
. On this basis the A. describes phases with higher and lower frequencies of extreme rains and floods in Europe in a regionally-differentiated manner. The phase of the Little Ice Age is well expressed throughout Europe, although its particular events were never
Some socio-ecological aspects of agricultural land-use under tropical heavyrain conditions. A case study of Naravi village, south India in Géographie et écologie des milieux tropicaux.

This study aimed first to clarify the distribution and diurnal variability of Mesoscale Convective System (MCS) occurences and their relations to the in-situ records of heavyrain events in the SW area including complex topography

This paper explores the meteorological causes and predictability of the South-Central Texas Flood. A composite analysis identifies the large-scale weather patterns associated with extreme rain in Texas. The 2002 event is compared to these composite
simulations is then described to investigate the ability of numerical models to reliably predict the amount and location of heavy rainfall during this event.
