Weighted ensemble analysis of extreme precipitation under climate change
The frequency or intensity of heavy precipitation has likely increased in North America since 1950s. In order to analyze climate change impacts on extreme precipitation events in Chicago area, historical (1961-2000) and projected (2046-2065, 2081-2100) daily precipitation data are calculated from …

Trends and projections of extreme precipitation over the contiguous United States
… trends in contiguous United States (CONUS) extreme precipitation events were examined in CMIP5 models, using, as a metric, the Extreme Precipitation Index (EPI) and a similar method based on the EPI. An increasing trend over the CONUS was found in the EPI, with variation among seven …

Identification and simulation of extreme precipitation using a computationally inexpensive methodology
An examination of characteristics extreme precipitation in the greater Cape Town region is undertaken. Thereafter, an investigation into the characteristics of these changes is made using two approaches. The first is an empirical methodology to explore the historical attributes of extreme events …

Economic impacts and analysis methods of extreme precipitation estimates for eastern Colorado
… they must withstand, in their lifetimes, any extreme precipitation event in their drainage basin. Correct estimation of this event is critical because on one hand it must provide an adequate level of safety to not occur, but it must not be any greater than needed since the high costs of dam …

Assessing Variabilities of Extreme Precipitation and Snow Depth Using Climate and Stochastic Models
… disasters. Climate change, with its associated extreme weather patterns, has exacerbated the frequency and intensity of these events. Specifically, heavy rainfall and rapid snowmelt have triggered extensive flooding in multiple provinces. As global temperatures rise and weather patterns change, …

Meteorological causes of extreme precipitation events that lead to flooding in Southeast Michigan
Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2027-05-01

Effect of latent heating on mesoscale vortex development during extreme precipitation: Colorado, September 2013
… to the Colorado Front Range, resulting in extreme precipitation and flooding. The heaviest precipitation during the September 2013 event occurred over the northern Colorado Front Range, producing a 7-day total of over 380 mm of rain. The flash flooding caused over $3 billion in damage to …

Weather extremes in a changing climate: analyses for extreme precipitation, severe hail, and tornadoes
… that often accompany severe thunderstorms: extreme precipitation, severe hail, and tornados. First, observational data and an ensemble of climate change model experiments (from the Coupled Model Intercomparison Project Phase 5 (CMIP5)) are used to examine past and potential future seasonal …

The Effects of Anthropogenic Warming on Changes of Extreme Precipitation Over Kansas City Metropolitan Area
… to investigate potential changes to the region’s precipitation under various global warming and cooling scenarios.

Improving Convective Permitting Model Simulations of Extreme Precipitation using Object-Based Tracking and Data Assimilation
… satellite-based MCS tracking and multiple precipitation datasets, we show that the CPM significantly better captures MCS frequencies and associated extreme rainfalls than coarse-grained (e.g. 3 km) ensemble models. Probabilistic verification illustrates that CPM has a much better skill to …

The effects of future extreme precipitation events on stream hydrology and hydraulics of stream crossing structures
… of climate is part of realistic training and extreme storm events and associated flooding risks can temporarily limit access to training lands and other training features such as water crossings. If an increase in intensity and incidence of extreme precipitation events is realized, …

Characteristics of precipitation and extreme precipitation events over the Drakensberg Mountain range in past and future climates
… natural resources in Southern Africa because precipitation over the mountains is the source of rivers that support socio-economic activities in Lesotho, South Africa, and Namibia. Meanwhile, extreme precipitation events over the Drakensberg are a threat to the communities around the mountains. …

Model post-processing for the extremes: improving forecasts of locally extreme rainfall
… investigates the science of forecasting locally extreme precipitation events over the contiguous United States from a fixed-frequency perspective, as opposed to the traditionally applied fixed-quantity forecasting perspective. Frequencies are expressed in return periods, or recurrence intervals; …

Analysis of Extreme Reversals in Seasonal and Annual Precipitation Anomalies Across the United States, 1895-2014
… effects of natural hazards may well increase, as extreme events would increasingly affect concentrated populations and the infrastructure upon which they rely. Extreme precipitation is one natural hazard that could stress concentrated populations, and climate change research is engaging heavy …

Extreme weather events in the upper Midwest: Implications on flood risk, crop yield, and water quality
… presents a comprehensive analysis of extreme weather events in the Upper Midwest, focusing on their impacts on flood risk, crop yield, and water quality. Through a series of interconnected studies, the research provides critical insights into the complex effects of extreme …

Exploring the Hydroclimatology of Floods: From Detection to Attribution
… understanding through linking hydrological extremes to large-scale climate drivers. In Ireland, recent years have highlighted vulnerability to flooding yet little research has been undertaken exploring hydroclimatic signatures of change in extremes at different scales, in part due to a lack …

Future changes in extreme rainfall events and circulation patterns over southern Africa
Changes in precipitation extremes are projected by many global climate models as a response to greenhouse gas increases, and such changes will have significant environmental and social impacts. These impacts are a function of exposure and vulnerability. Hence there is critical need to understand …
