Climate change and heavy rain events in the central U.S.
Abstract
Floods are one of the most destructive weather-related natural hazards, annually responsible for hundreds of millions of dollars of damage in the United States. The 1993 Upper Mississippi River flood was particularly devastating, with losses estimate at $15--20 billion. Climate change caused by anthropogenic releases of trace gases into the atmosphere may potentially affect the frequency and/or intensity of the meteorological conditions that cause floods. Flood control structures often have lifetimes of 50 to 100 years or more. Since design decisions are being made today for flood control structures that will still be in operation in the late 21st century, it is important to study the possibility that changes in flooding may result due to possible climate change. In this paper, the authors describe an analysis of heavy precipitation events. In particular, they identify the principal meteorological conditions that are associated with these events. An approach to assessing the impacts of climate change on flood-producing heavy rain events is outlined. Kunkel et al. (1993) found that floods on small streams in the central US could be closely related to large rain accumulations over 5--10-day periods. Typically, these accumulations are the result of two or more sizable individual events. The firstmore »

(1993) found that floods on small streams in the central US could be closely related to large rain accumulations over 5--10-day periods. Typically, these accumulations are the result of two or more sizable individual events. The first event may set the stage by creating wet topsoils. The following events then result in high runoff. The present study focuses on these multiday events as a primary meteorological cause of floods. Obviously other factors, such as antecedent soil moisture, play a role in determining the exact amount and temporal distribution of runoff for any particular event. This analysis thus represents a first-order look at possible changes in flooding due to climate change.},
