Similarly, the maximum
daily precipitation shows isolated patches across Europe with larger than normal values.

«We
show that at the present - day warming of 0.85 °C about 18 % of the moderate
daily precipitation extremes over land are attributable to the observed temperature increase since pre-industrial times, which in turn primarily results from human influence,» the research team said.
To solve this problem I looked at three patterns of the 6558 day period, overlaid them at the
daily weather data level, and plotted the resultant combined signal for
Precipitation, and temperature patterns for the USA, extended that cyclic interpenetration for a six year period, and plotted out maps to
show the repeating reoccurring patterns in the global circulation, as a (6 year long stretch, we are now ~ 40 months into the posted 6 years long) forecast for part of the current repeat of the 6558 day long cycle.
Figure 9.6: Maps
show the increase in frequency of extreme
daily precipitation events (a
daily amount that now occurs just once in 20 years) by the later part of this century (2081 - 2100) compared to the latter part of the last century (1981 - 2000).
Figure 2.19: Maps
show the increase in frequency of extreme
daily precipitation events (a
daily amount that now occurs once in 20 years) by the later part of this century (2081 - 2100) compared to the later part of last century (1981 - 2000).
More than one - half of the stations
showed a significant positive relationship at the
daily time scale between warm nights (
daily minimum temperature greater than the 90th percentile) or warm days (
daily maximum temperature above the 90th percentile) and heavy -
precipitation events (
daily precipitation exceeding the 75th percentile), with the greater frequencies found for the east and southwest coasts during autumn and winter.
NASA animation
showing precipitation concentrated in the tropics in the form of average
daily rainfall rates during the month of January from 1998 - 2007.
IPCC projections do not
show obvious threshold behavior this century (12), but they do agree that sulfate aerosols would dampen the strength of ISM
precipitation, whereas increased greenhouse gases increase the interannual variability of
daily precipitation (69).
Indicators based on
daily precipitation data
show more mixed patterns of change but significant increases have been seen in the extreme amount derived from wet spells and number of heavy rainfall events.
