Recent Directions in Extreme Precipitation Studies and Planning Methods Introduced at the California Extreme Precipitation Symposium

On extreme daily precipitation totals at Athens, Greece

The paper studies changes in daily precipitation records at the National Observatory, Athens, during the period 1891–2004. This is the longest available time series of precipitation for Greece. The results show that both the shape and scale parameter of a fitted two parameter gamma distribution for the last two decades do show a significant difference of these parameters, when compared to any p...

Occurrence of Extreme Precipitation Events in California and Relationships with the Madden–Julian Oscillation

California receives most of the annual precipitation during the boreal winter season. Additionally, large spatial and temporal variations in the total rainfall amounts are observed. This study investigates the occurrence of extreme precipitation events in California and the modulation by the Madden–Julian oscillation (MJO). Three questions are investigated. 1) Are extreme precipitation events i...

Extreme precipitation and extreme streamflow in the Dongjiang River Basin in southern China

Papers published in Hydrology and Earth System Sciences Discussions are under open-access review for the journal Hydrology and Earth System Sciences Abstract Extreme hydro-meteorological events have become the focus of more and more studies in the last decade. Due to the complexity of the spatial pattern of changes in precipitation processes, it is still hard to establish a clear view of how pr...

Climatic Variations in Extreme Precipitation in the Midwest

In the Midwest, signi cant interannual to decadal variations in precipitation and stream ow have been observed over the latter part of this century. Yet in studies of precipitation frequency, engineers and hydrologists assume that natural climate variability does not a ect the probability distribution of extreme precipitation. A regional approach is used to test this assumption for extreme prec...
