The top 10 events from the 100-yr, 24-h threshold, ranked by the highest number of points per event. (a) 10 min precipitation rates as observed at Houston, TX (mm hr −1), … In the year 2000, there were 20 days with very heavy rainfall. The prevalence of extreme single-day precipitation events remained fairly steady between 1910 and the 1980s, but has risen substantially since then. The highest number of extreme rain events … Extreme weather or extreme climate events includes unexpected, unusual, severe, or unseasonal weather; weather at the extremes of the historical distribution—the range that has been seen in the past. Extreme precipitation events are important indicators to measure intensity and frequency of precipitation which are very sensitive to climate change . Increase in extreme rainfall In the first scientific analysis of observed data, a team of researchers from the Indian Institute of Technology Bombay (IITB) and National Institute of Hydrology (NIH) found that between 1980-91 and 1992-2003, extreme rainfall events in the Sutlej river basin in Himachal Pradesh and the Ganga headwaters in Uttarakhand have more than doubled. Mean nest temperature during the twenty days that followed an extreme rainfall event (light gray area) was 30.7°C ( ), whereas it would have been 32.4°C in the absence of rainfall (+). This section reviews the different definitions of “extreme” rainfall used in the climate science and flood hydrology literature (section 5.1), the relationship between the duration of extreme rainfall events and catchment characteristics and the magnitude of the ensuing floods (section 5.2), and the broader meteorological context of floods (section 5.3). In 1950, 15 days with very heavy rainfall were recorded. Extreme Rainfall Events and Lake Level Changes in East Africa 64 2.2 1997 During the last few months of 1997, widespread heavy rainfall caused flooding across the East and the Horn of Africa. Source of Rainfall Data "BoM - Bureau of Meteorology Climate Archives EWSD - Engineering and Water Supply Department, South Australia MW - Melbourne Water, Victoria PAWA - Power and Water Authority, Northern Territory Private - Privately owned rain gauge PWD - … Subsequent updates to data may result in minor changes to some values. Many events of extreme rainfall share characteristics, such as high moisture and an atmospheric disturbance (i.e., a winter storm, warm/cold front or tropical cyclone). Storms happen every year, if not here then somewhere. In 1916, there were 6 days with very heavy rainfall. Extreme rainfall has devastating consequences for societies and economies. Some extreme rainfall events that occurred over the central and eastern United States are nocturnal (Winkler et al., 1988). Suburbs of Sydney experienced the worst flooding in 60 years, and the events were described by NSW Premier Gladys Berejiklian as "one in 100-year" flooding. Extreme precipitation events have produced more rain and become more common since the 1950s in many regions of the world, including much of the United States. During the extreme events, heavy rainfall is located mainly in the NEI without much spread in the aerial domain. Extreme rainfall statistics may shift as U.S. climate warms. NCEI provides a variety of information detailing these events categorized by type of event. The NPCC study projects that 1-, 2-, and 4 inch 24-hour rainfall events are expected to increase in frequency, intensity, and duration in New York City.9 Maps. Days with ‘very heavy rainfall’ are classed as days with rainfall totalling at least 30mm. 2014). In the U.S., the Midwest and Northeast have seen the strongest increases in heavy precipitation events. State-wide and point-location assessments of long-term trends in days with very heavy rainfall are complicated, due to the impact of site changes, incomplete datasets, and a low number of high quality recording sites from which data are available. More than 50 flights have been diverted due to waterlogging. Extreme rainfall events have many labels. Thirty‐two extreme events such that rainfall of the day exceeds the 90th percentile were identified. More intense rain events, fewer rain days, and longer droughts are forecasted in high latitude areas of Europe (Beniston et al. Extreme rainfall on the east coast of Australia beginning on 18 March 2021 led to widespread flooding in New South Wales, affecting regions from the North Coast to the Sydney metropolitan area in the south. Heavy rainfall events are mostly associated either with deep cloud systems or of persistent cloud systems of a different kind (Houze et al., 2017). SWB - &Water Board, Sydney-Illawarra-Blue Mountains, New South Wales Factors influencing extreme rainfall events and floods. Proof. EWSD - Engineering and Water Supply Department, South Australia Additionally, event attribution studies have identified an increased probability of some individual extreme precipitation events in this region due to anthropogenic influence (4, 5), including hurricane-induced rainfall .
