An increased risk of intense, short - duration rainfall events in mid-latitude regions has been predicted consistently for well over a decade as part of the pattern of human influence on precipitation.

Links between monsoon - related events (rainfall over South Asia, rainfall over East Asia, NH circulation, tropical Pacific circulation) weakened between 1890 and 1930 but strengthened during 1930 to 1970 (Kripalani and Kulkarni, 2001).

Some areas received well over their annual rainfall during this event.

If we were to argue that other events would require anomalous rainfall over Australia's interior basins comparable to that in 2010 - 11, then we could use the rainfall record to infer such sea level drops.

We are already seeing more intense storms and more heatwaves and higher extreme rainfall events, all at damaging levels so it can only get worse over the next 30 years imho.

Further complicating the use of these proxies is the fact that the deviation in oxygen - 18 ratios is affected by the amount of TC rainfall, the distance from the center of the cyclone at which the rain was produced, and the intensity of the cyclone — so I doubt these proxies alone will enable disentangling intensity and rainfall, tnough a large number of samples over an area could reveal information about the track and extent of the TC event.

But perhaps the most dangerous feature of the whole event is the severe rainfall totals that are expected to accumulate over the next three days.

His examination of these extreme events — snow, storms, rainfall — shows an absence of evidence to indicate marked change over recent decades.»

Potentially more worrying, the 2015/2016 floods appear to be part of a trend over recent decades for more frequent extreme winter rainfall events.

However, the report does say it is very likely that there will be more intense precipitation events over many areas, and that peak winds and rainfall rates from hurricanes are also likely to be higher.

As in that study, they analyzed the history of rainfall measurements in the region to work out just how unusual the incredible rainfall totals from Harvey were — and whether the chances of an event like that have changed over time.

Climate studies clearly show that extreme rainfall events would increase over the Indian subcontinent and that the Himalayan range is particularly vulnerable.

Such events would likely be driven by extended periods of rainfall over the ice during summer heating events.

He says average rainfall for Australia will decrease, but the extreme weather events will be on the rise, so while you might get less rain over the year it will come in the form of damaging storms and stronger winds which feel like so - called freak events.

In the new study, the researchers define an «extreme» event by the size of the rainfall shift from the west Pacific over to the normally dry east Pacific.

Finally, there's our vulnerability to heavy rainfall events, in this case exacerbated by the city's rapid expansion that has paved over former grasslands, overloaded critical infrastructure, challenged urban planning, and limited evacuation routes.

Climate change already is being felt in the form of warmer winters in New York over the last several decades and increasing numbers of extreme rainfall events, according to DeGaetano, the Cornell researcher, who is the director of the Northeast Regional Climate Center at Cornell.

In particular, over NH land, an increase in the likelihood of very wet winters is projected over much of central and northern Europe due to the increase in intense precipitation during storm events, suggesting an increased chance of flooding over Europe and other mid-latitude regions due to more intense rainfall and snowfall events producing more runoff.

The events were triggered by a period of intense rainfall and a rapid rise in temperatures, which rose by 27 ˚C in a little over two days.

The adjacent chart depicts the distribution of the top 50 DeBilt, Holland rainfall events while atmospheric CO2 levels increased over the decades.

It is further argued that the transition of vertical circulation patterns is in response to adjustments to geostrophic imbalance — an adjustment time scale of 6 — 9 h. Although unproven, we suggest that antecedent rainfall over the alkali desert 2 weeks prior to the event was instrumental in lowering the bulk density of sediments and thereby improved the chances for dust ablation by the atmospheric disturbance.

The frequency of heavy precipitation events (or proportion of total rainfall from heavy falls) will be very likely to increase over most areas during the 21st century, with consequences for the risk of rain - generated floods.

Because droughts progress over years, it takes a prolonged period of rainfall or a massive rainfall event to break them.

The non-linearities are emergent properties of the complex interconnectivity of the many parts of the earth climate system — The presence and amplitude of El Nino changes the rainfall in the southeastern US, which affects evapotranspiration and cloudiness over the warm parts of the Atlantic, which affects the amount of sensible and latent heat which goes into the atmosphere, which the prevailing winds carry to Great Britain, and so on through a chain of events which eventually influence the barometric pressure differences between the Eastern and Western Pacific which drive the ENSO.

Published in the journal Hydrological Sciences, the study looks at data sets from 1884 to 2013 and found an upward trend in reported flooding, with flood events appearing more frequently towards the end of the 20th century, peaking in 2012 when annual rainfall was the second highest in over 100 years.
