Sentences with phrase «mean precipitation rate»

Understanding how the global - mean precipitation rate will change in response to a climate forcing is a useful thing to know.

Figuring how this would influence the global mean precipitation rate is well beyond what I can do in my head.

Not exact matches

Loss of the afternoon data would mean a «50 % error increase in [forecasting] precipitation rates in southern US,» according to a NOAA presentation.

The review by O'Gorman et al (3) reports that a 1C increase in global mean temperature will result in a 2 % — 7 % increase in the precipitation rate; the lower values are results of GCM output, and the upper values are results from regressing estimated annual rainfalls on annual mean temperatures.

Although WUE was positively correlated with CUE, NPP, and LAI, average baseline WUE was highest in grassland systems, which also had lower rates of mean annual NPP, precipitation, and LAI.

Most precipitation in this coastal area takes place in the months of December, January, and February with a monthly mean rate of 2.0 - 3.3 in.

Although WUE was positively correlated with CUE, NPP, and LAI, average baseline WUE was highest in grassland systems, which also had lower rates of mean annual NPP, precipitation, and LAI.

Because latent heat release in the course of precipitation must be balanced in the global mean by infrared radiative cooling of the troposphere (over time scales at which the atmosphere is approximately in equilibrium), it is sometimes argued that radiative constraints limit the rate at which precipitation can increase in response to increasing CO2.

«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..

There are no mean rate precipitation fields - the precipitation fields are accumulated from the beginning of the forecast for + step hours.

Based on process understanding and agreement in 21st century projections, it is likely that the global frequency of occurrence of tropical cyclones will either decrease or remain essentially unchanged, concurrent with a likely increase in both global mean tropical cyclone maximum wind speed and precipitation rates.

Twelve - month running means of precipitation rate (mm / day) from January 1979 to May 2017 evaluated over NW, NE, SW and SE Europe for ERA - Interim, part of ERA5, JRA - 55, GPCC and (to March 2017) GPCP.

All of these characteristics (except for the ocean temperature) have been used in SAR and TAR IPCC (Houghton et al. 1996; 2001) reports for model - data inter-comparison: we considered as tolerable the following intervals for the annual means of the following climate characteristics which encompass corresponding empirical estimates: global SAT 13.1 — 14.1 °C (Jones et al. 1999); area of sea ice in the Northern Hemisphere 6 — 14 mil km2 and in the Southern Hemisphere 6 — 18 mil km2 (Cavalieri et al. 2003); total precipitation rate 2.45 — 3.05 mm / day (Legates 1995); maximum Atlantic northward heat transport 0.5 — 1.5 PW (Ganachaud and Wunsch 2003); maximum of North Atlantic meridional overturning stream function 15 — 25 Sv (Talley et al. 2003), volume averaged ocean temperature 3 — 5 °C (Levitus 1982).

-- First we increase the greenhouse gases — then that causes warming in the atmosphere and oceans — as the oceans warm up, they evaporate more H2O — more moisture in the air means more precipitation (rain, snow)-- the southern hemisphere is essentially lots of water and a really big ice cube in the middle called Antarctica — land ice is different than sea ice — climate models indicated that more snowfall would cause increases in the frozen H2O — climate models indicated that there would be initial increases in sea ice extent — observations confirm the indications and expectations that precipitation is increasing, calving rates are accelerating and sea ice extent is increasing.

Pre-TAR AOGCM results held at the DDC were included in a model intercomparison across the four SRES emissions scenarios (B1, B2, A2, and A1FI) of seasonal mean temperature and precipitation change for thirty - two world regions (Ruosteenoja et al., 2003).9 The inter-model range of changes by the end of the 21st century is summarised in Figure 2.6 for the A2 scenario, expressed as rates of change per century.
