Extreme rainfall projected to become more severe, frequent with warming（图）
Extreme rainfall projected frequent warming
2020/11/20
Across the continental United States, massive, often-devastating precipitation events -- the kind that climate scientists have long called "hundred-year storms" -- could become three times more likely...
Heavy rainfall drives one-third of nitrogen runoff, according to new study（图）
Heavy rainfall drives one-third nitrogen runoff according new study
2020/11/13
Heavy rain events that occur only a few days a year can account for up to one-third of the annual nitrogen runoff from farmland in the Mississippi River basin, according to a new study by Iowa St...
Imagine a tropical forest, and you might conjure up tall trees hung with vines, brightly colored birds, howling monkeys and ... rain. Indeed, precipitation patterns, along with temperature, dictate wh...

Climate change projected increase seasonal East African rainfall
2020/8/21
Rainfall during the season known as the "short rains" is expected to rise significantly in East Africa over the next few decades in response to increased greenhouse gases, according to research led by...
Research Finds Link Between Rainfall And Ocean Circulation In Past And Present（图）
Research Rainfall Ocean Circulation Past Present
2018/2/1
Research conducted at The University of Texas at Austin has found that changes in ocean currents in the Atlantic Ocean influence rainfall in the Western Hemisphere, and that these two systems have bee...
Rainfall-runoff risk characteristics of urban function zones in Beijing using the SCS-CN model
SCS-CN model urban function zone spatial cluster runoff risk
2018/4/9
Urbanization significantly increases the risk of urban flooding. Therefore, quantitative study of urban rainfall-runoff processes can provide a scientific basis for urban planning and management. In t...
Evaluation of discrepancies in spatial distribution of rainfall erosivity in the Czech Republic caused by different approaches using GIS and geostatistical tools
covariate geostatistics R factor rainfall intensity rainfall total USLE/RUSLE-GIS method
2017/6/26
The study presents all approaches of rainfall erosivity factor (R) computation and estimation used in the Czech Republic (CR). A lot of distortions stem from the difference in erosive rainfall criteri...
Comparison of different approaches to LS factor calculations based on a measured soil loss under simulated rainfall
geographic information systems topographic factor universal soil loss equation water erosion
2017/6/26
Geographic Information Systems (GIS) in combination with soil loss models can enhance evaluation of soil erosion estimation. SAGA and ARC/INFO geographic information systems were used to estimate the ...
A new study by researchers from MIT and the Swiss Federal Institute of Technology in Zurich shows that the most extreme rain events in most regions of the world will increase in intensity by 3 to 15 p...
A University of Connecticut climate scientist has confirmed that more intense and more frequent severe rainstorms will likely continue as temperatures rise due to global warming, despite some observat...
