«Since the AR4, there is some new limited direct evidence for an anthropogenic influence on extreme precipitation, including a formal detection and attribution study and indirect evidence that extreme precipitation would be expected to have increased given the evidence of anthropogenic influence on various aspects of the global hydrological cycle and high confidence that the intensity of extreme precipitation events will increase with warming, at a rate well exceeding that of the mean precipitation..

Feynman andRuzmaikin (1999) found that, «the intensity of cosmic rays incident on the magnetopause has decreased markedly during this century,» i.e., the twentieth century (and also that, «the pattern of cosmic ray precipitation through the magnetosphere to the upper troposphere has also changed.»

Accordingly, there is less certainty about the changes in frequency and intensity of tropical cyclones on a regional basis than for temperature and precipitation changes.

For the entire Northern Hemisphere, there is evidence of an increase in both storm frequency and intensity during the cold season since 1950,1 with storm tracks having shifted slightly towards the poles.2, 3 Extremely heavy snowstorms increased in number during the last century in northern and eastern parts of the United States, but have been less frequent since 2000.11,15 Total seasonal snowfall has generally decreased in southern and some western areas, 16 increased in the northern Great Plains and Great Lakes region, 16,17 and not changed in other areas, such as the Sierra Nevada, although snow is melting earlier in the year and more precipitation is falling as rain versus snow.18 Very snowy winters have generally been decreasing in frequency in most regions over the last 10 to 20 years, although the Northeast has been seeing a normal number of such winters.19 Heavier - than - normal snowfalls recently observed in the Midwest and Northeast U.S. in some years, with little snow in other years, are consistent with indications of increased blocking (a large scale pressure pattern with little or no movement) of the wintertime circulation of the Northern Hemisphere.5 However, conclusions about trends in blocking have been found to depend on the method of analysis, 6 so the assessment and attribution of trends in blocking remains an active research area.

No matter the probability or intensity of USGS ARkStorm it would have to drop precipitation (not snowpack which melts slower) where the watersheds are for the 10 dams in Northern California shown on the map at the following link (the 2 dams in Southern California only receive water from the Northern Cal dams and should not be considered): Link

The colour field underneath the wind arrows shows the precipitation rate on a scale from 0 to 20 mm per hour, noting that peaks in rainfall intensity (which may have been far higher than 20 mm / hr at times in localised regions within the Hurricane circulation), are not resolved in this animation.

The multiple physical connections between lightning, convection, precipitation, and rapid storm intensity changes make lightning a rich source of information on how these storms evolve.

Area - averaged precipitation data (terciles) for south - west eastern Australia was classified on the basis of STR intensity and position.

Data analyses have found an increase of drought intensity at many locations [130]--[131] The magnitude of change depends on the drought index employed [132], but soil moisture provides a good means to separate the effect of shifting seasonal precipitation and confirms an overall drought intensification [37].

You mention possible ways to get empirical data to either validate or falsify your hypothesis regarding wind intensity based on precipitation.

Because precipitation comes mainly from weather systems that feed on the water vapour stored in the atmosphere, this has generally increased precipitation intensity and the risk of heavy rain and snow events.

But California droughts are also fundamentally linked to the quantities and timing of precipitation, the dynamics of storm formation in the Pacific Ocean, the impacts of climate change on the frequency and intensity of El Niño and La Niña events and the Pacific Decadal Oscillation, and the behavior of the jet stream as conditions in the Arctic change.

Gavin said upfront: «By looking at the signatures of climate change in precipitation intensity and comparing that to the internal variability and the observation, the researchers conclude that the probability of intense precipitation on any given day has increased by 7 percent over the last 50 years — well outside the bounds of natural variability».

Incidentally, those who claim the extreme 2005 hurricane season is entirely due to a natural cycle, like Bill Gray, also say it is due to warmer ocean temperatures — the difference in opinion is in why the ocean temperatures are so warm, not in the effect this has on hurricane intensity or precipitation.

Trenberth did say something both to the point and scary, to wit, that based on studies of hurricane INTENSITY, he calculates that 1 ″ of extra precipitation was dumped into area around New Orleans because of global climate changes.

According to this latest study, an 80 year build - up of atmospheric CO2 at 1 % / yr (compounded) leads to roughly a one - half category increase in potential hurricane intensity on the Saffir - Simpson scale and an 18 % increase in precipitation near the hurricane core.

Based on our published results and as well as those of other modeling groups, we conclude that at the global scale: a future increase in tropical cyclone precipitation rates is likely; an increase in tropical cyclone intensity is likely; an increase in very intense (category 4 and 5) tropical cyclones is more likely than not; and there is medium confidence in a decrease in the frequency of weaker tropical cyclones.

«Whereas if it relies on multiple environmental conditions — like sunlight intensity, wind speed, precipitation — all of these factors could create a more stable power source with a higher power output.»
