Not exact matches

Variations in the thickness of the layers is determined by a combination of the amount of water seeping into the cave and the concentration of carbon dioxide in the cave's atmosphere so, when conditions are right, they can provide a measure of how the amount of precipitation above the cave varies over time.

The Midwest has seen a 37 percent increase in the amount of rain falling in heavy precipitation events since the late 1950s, the second - highest increase in the U.S. over that period.

In Relationships between Water Vapor Path and Precipitation over the Tropical Oceans, Bretherton et al showed that although the Western Pacific warmer surface waters increased the water in the atmosphere compared to the Eastern Pacific, rainfall was lower in the Western Pacific compared to the Eastern Pacific for equal amounts of water vapor in the atmospheric column — e.g., about 10mm / day in the Western Pacific, versus ~ 20mm / day in the Eastern Pacific at 55 mm water vapor, the peak of the distribution of water vapor amounts.

Tropical land - surface precipitation measurements indicate that precipitation likely has increased by about 0.2 to 0.3 % / decade over the 20th century, but increases are not evident over the past few decades and the amount of tropical land (versus ocean) area for the latitudes 10 ° N to 10 ° S is relatively small.

On average in the United States, the amount of rain falling during the heaviest 1 percent of rainstorms has increased nearly 20 percent during the past 50 years — almost three times the rate of increase in total precipitation.4, 5 The Midwest saw an even larger average increase of 31 percent, surpassed only by the Northeast (at 67 percent).4 Scientists attribute the rise in heavy precipitation to climate change that has already occurred over the past half - century.6

Average water conditions: The amount and distribution of precipitation within a drainage basin and the run off conditions present as determined by reviewing the area water supply records over a long period of time.

Snowfall varies across the region, comprising less than 10 % of total precipitation in the south, to more than half in the north, with as much as two inches of water available in the snowpack at the beginning of spring melt in the northern reaches of the river basins.81 When this amount of snowmelt is combined with heavy rainfall, the resulting flooding can be widespread and catastrophic (see «Cedar Rapids: A Tale of Vulnerability and Response»).82 Historical observations indicate declines in the frequency of high magnitude snowfall years over much of the Midwest, 83 but an increase in lake effect snowfall.61 These divergent trends and their inverse relationships with air temperatures make overall projections of regional impacts of the associated snowmelt extremely difficult.

These twelve - month running - mean time series of precipitation amounts averaged over continental land areas and the European sub-regions include values from JRA - 55 and values available to date from ERA5, the reanalysis currently in production to supersede ERA - Interim.

The principle difference over Europe is in the amount of precipitation over the north - east of the continent, where GPCP provides systematically higher values than either GPCC or E-OBS, and ERA - Interim gives values in between.

Site environmental variables in 2007 — 13: daily precipitation (annual amounts noted); daily mean soil water content at 30 cm below surface (SWC); daily maximum vapor pressure deficit (VPD); daily mean air temperature over the forest canopy (Ta).

Dust impact on climate has varied over time, depending on the amount of dust particles in the atmosphere and therefore on aspects like vegetation, wind strength, and precipitation patterns (8 ⇓ — 10).

Climate adaptation must therefore account for the greatest precipitation amounts that may be expected over a certain time span3.

• Topographic features such as mountains play an important role in the amount of precipitation that falls over an area.

And as far as precipitation goes, the trends down there are all over the place — some stations show trends towards increasing rainfall amounts, while others nearby, towards decreasing amounts.

A drought / deluge / drought sigmoid is much less advantageous than equipartition of an equal amount of precipitation over time, in particular if we do not know the lengths of droughts and deluges to expect.

You do realize that once you have a reasonable estimate for the amount of precipitation that falls over the earth then it is trivial to compute how much heat is transported by the evaporation / condensation mechanism?
