Events like heat waves almost certainly bear a human imprint, the report said, and many droughts and
heavy rain events do, too.
Other factors that often play a role in the winter weather include the Arctic Oscillation, which influences the number of arctic air masses that penetrate into the South and create nor'easter s on the East Coast, and the Madden - Julian Oscillation, which can affect the number of
heavy rain events in the Pacific Northwest.
Consistent with earlier research, six of the top 10 states with the biggest increases in number of days with heavy downpours are in the Northeast, including Rhode Island, Maine, and New Hampshire, which have seen the number
of heavy rain events in the last decade increase by at least 50 percent compared to the 1950s.
Precipitation does not follow quite the same pattern, but the same concept applies: fewer light and moderate rains are being replaced by
more heavy rain events.
Catastrophic flooding, often driven by
unexpectedly heavy rain events, has swept through many states, and many of those big rain events caught people by surprise in places like Houston and Baton Rouge, La..
But overall, the simulations showed a small but significant increase in likelihood of
extremely heavy rain events for the south of England.
The local people also reported, that Lepidium species do cause diarrhea in cattle and
after heavy rain events herders do not let their livestock out to the pastures before noon.
-- We have realized how sensitive convective storms (thunderstorms and
other heavy rain events) are to the humidity of the air around them, and we are beginning to account for that in our climate models
Their new 100 million pound computer is designed to overcome this problem and in particular to
forecast heavy rain events in the narrow valleys that are prone to flooding the towns at the bottom, such as Boscastle.
«When warm, wet air meets cold air, the water vapour turns to rain and since there is more water vapour, we are getting these
very heavy rain events and subsequent flooding,» he said.
As heavy rains continue today, this storm may showcase the combined effect of
a heavy rain event coupled with a prolonged storm surge.
Between May and October, China experienced 35
heavy rain events.
Heat waves are hotter,
heavy rain events are heavier, and winter storms have increased in both frequency and intensity.
Confidence in the latter is not related to TC intensity or frequency; it comes from the probable increase in
heavy rain events and the inevitable rise in sea level that will make it easier for storm surges to go inland.
The authors commented, «These findings are in tune with model projections and some observations that indicate an increase in
heavy rain events and a decrease in weak events under global warming scenarios.»
Nevertheless
the heavy rain events just before or during the death event, did certainly lead to very moist fodder especially in the morning hours.
Heavy rain events may also pose a potential health risk; one recent study found that about half of all waterborne disease outbreaks in the U.S. (between 1948 and 1994) were linked to days of very heavy rain.
In fact, observations over the last 60 years indicate that over the United States, the amount of water falling in
heavy rain events has increased substantially, and an astonishing 71 percent over portions of the mid-Atlantic and northeastern U.S.
Projected changes include: increases to the intensity and frequency of
heavy rain events; longer, hotter, drier summers and milder winters with reduced snowpack at lower elevations.
How human influence affected other types of events such as droughts,
heavy rain events, and storms was less clear, indicating that natural variability likely played a much larger role in these extremes.
For example, in snow events or
heavy rain events, having access to high density surface data will give extra confidence in the extent and development of such events, helping provide rapid updated guidance on the evolution of such weather situations.
Droughts, heatwaves,
heavy rain events, cyclones, storms: they just haven't increased in the alarmists assured us they would.
