Assessing the Spatial and Temporal Patterns of Seasonal Precipitation Extremes and the Potential Influencing Factors in Dongting Lake Basin, China
The Dongting Lake Basin (DTLB) of China is a flood prone area. Knowledge of the spatiotemporal characteristics and risks of precipitation extremes is essential for flood mitigation. Based on the precipitation amount (R), precipitation intensity (Ri), max 1 day precipitation amount (Rx1) and max 5 day precipitation amount (Rx5), this study analyzed the spatial-temporal patterns, risks and invest...
متن کاملOn the variability of return periods of European winter precipitation extremes over the last three centuries
We investigate the changes of extreme European winter (December-February) precipitation back to 1700 and show for various European regions that return periods of extremely wet and dry winters are subject to significant changes both before and after the onset of anthropogenic influences. Generally, winter precipitation has become more extreme. We also examine the spatial pattern of the changes o...
متن کاملA Long-term (~50-yr) Historical Perspective on Flood-generating Winter Storms in the American River Basin
Because of the broad range of altitudes spanned by its catchment, the American River is notable for its occasional, very large winter floods. These floods typically are spawned by warm and exceptionally wet storms that deposit heavy rain or wet snows on broad expanses of the river’s watershed, generating rapid runoff and high streamflows. On flood and longer time scales, the American River is n...
متن کاملChanges in winter precipitation extremes for the western United States under a warmer climate as simulated by regional climate models
[1] We find a consistent and statistically significant increase in the intensity of future extreme winter precipitation events over the western United States, as simulated by an ensemble of regional climate models (RCMs) driven by IPCCAR4 global climate models (GCMs). All eight simulations analyzed in this work consistently show an increase in the intensity of extreme winter precipitation with ...
متن کاملNonstationary Precipitation Intensity-Duration-Frequency Curves for Infrastructure Design in a Changing Climate
Extreme climatic events are growing more severe and frequent, calling into question how prepared our infrastructure is to deal with these changes. Current infrastructure design is primarily based on precipitation Intensity-Duration-Frequency (IDF) curves with the so-called stationary assumption, meaning extremes will not vary significantly over time. However, climate change is expected to alter...
