Because the models predict
little average precipitation increase nationwide over this period, the product of CAPE and precipitation gives about a 12 percent rise in cloud - to - ground lightning strikes per degree in the contiguous U.S., or a roughly 50 percent increase by 2100 if Earth sees the expected 4 - degree Celsius increase (7 degrees Fahrenheit) in temperature.

ACPI assumes a 1 percent annual increase in the rate of greenhouse gas concentrations through the year 2100, for
little change in
precipitation and an
average temperature increase of 1.5 to 2 degrees centigrade at least through the middle of 21st century.
The
average probability that some form of
precipitation will be observed in any given day is only 2 %, with
little variation over the month.
The probability of rainfall changes very
little throughout the month, with the
average chance of seeing some kind of
precipitation constant at 43 %.
July is the driest month, when there is an
average of 2 mm of
precipitation, whilst September is the wettest month, when an
average of 5 mm of rainfall occurs — showing just how
little rainfall Costa Adeje sees in summer.
The
average probability that some form of
precipitation will be observed in March is 32 % with
little variation.
«We're seeing increasing temperatures and relatively
little change in
average precipitation, but an increase in the variability and the occurrence of both wet and dry extremes,» said Daniel Swain, an atmospheric scientist at Stanford's School of Earth, Energy & Environmental Sciences and the lead author of a new paper published in Science Advances.
But Swain and his colleagues wanted to know if that was because there was really
little change in
precipitation or if there were big changes at either end of the spectrum that balanced each other out when looking at yearly
averages.
The researchers used recent historical data and not climate modeling, so the study does not make any future predictions, but Swain says the findings appear to be consistent with other climate research that reveals there is
little change in
average precipitation, but an increase in the amount of very wet or very dry periods.

Average temperature of the warmest month is below 10ºC (50ºF)
Little precipitation falls Winters = extremely cold Summer = cool Two Types Tundra Ice Caps
For example, analyses of glacier mass balances, volume changes and length variations along with temperature records in the western European Alps (Vincent et al., 2005) indicate that between 1760 and 1830, glacier advance was driven by
precipitation that was 25 % above the 20th century
average, while there was
little difference in
average temperatures.
December and January storms have helped, with
precipitation and snowpack mostly a
little above
average for this time of year.
