Sentences with phrase «mean precipitation decreased»

Not exact matches

has decreased in winter, but no significant change in annual mean precipitation potentially because of very slight increases in spring and fall precipitation; precipitation is projected to increase across Montana, primarily in spring; slight decrease in summer precipitation; variability of precipitation year - to - year projected to increase
Statewide precipitation has decreased in winter (0.14 inches / decade -LSB--0.36 cm / decade]-RRB- since 1950, but no significant change has occurred in annual mean precipitation, probably because of very slight increases in spring and fall precipitation.
In that case (along with greater precipitation, and the precipitation belt moving to higher latitudes), there could be more snow in the winter & greater melting in the summer (in higher latitudes), while I'd think the lower latitudes (with less precip) and the local mean temp being higher, would melt the glaciers faster, without adequate snowfall & low winter temps to slow this glacial decrease.
Decreases in precipitation over many subtropical areas are evident in the multi-model ensemble mean, and consistency in the sign of change among the models is often high (Wang, 2005), particularly in some regions like the tropical Central American - Caribbean (Neelin et al., 2006).
As for how this could be — and in light of the findings of the references listed above — Rankl et al. reasoned that «considering increasing precipitation in winter and decreasing summer mean and minimum temperatures across the upper Indus Basin since the 1960s,» plus the «short response times of small glaciers,» it is only logical to conclude that these facts «suggest a shift from negative to balanced or positive mass budgets in the 1980s or 1990s or even earlier, induced by changing climatic conditions since the 1960s.»
Hotter days mean more evaporation, worsening the impacts of droughts even when there isn't a significant decrease in precipitation.
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.
Increases in heavy precipitation have also been documented even when mean total precipitation decreases (for example, see Northern Japan in Figure 2.35, or Manton et al., 2001).
Projected temperature would increase by 2050 by about 2 °C above the current level (a warming similar to that predicted by the ensemble mean of the CMIP5 simulations) and precipitation would decrease by an additional 30 % compared to the current conditions.
While the HadCM3 - projected mean annual precipitation during 2070 to 2099 at El Reno, Oklahoma, decreased by 13.6 %, 7.2 %, and 6.2 % for A2, B2, and GGa1, respectively, the predicted erosion (except for the no - till conservation practice scenario) increased by 18 - 30 % for A2, remained similar for B2, and increased by 67 - 82 % for GGa1.
In the coming century, increasing atmospheric GHG concentration and associated warming could have important hydrological and water resource consequences in the Southwest resulting from mean state changes due to higher evaporation and decreased precipitation [73 — 75].
It is perfectly conceivable, for example, to have annual precipitation increase 10 to 20 % at the same time that mean annual surface water runoff decreases by 10 to 20 % (or even more).
Another aspect of these projected changes is that wet extremes are projected to become more severe in many areas where mean precipitation is expected to increase, and dry extremes are projected to become more severe in areas where mean precipitation is projected to decrease.
The long - term mean annual precipitation decreased from 816 mm year − 1 at the moist to 544 mm year − 1 at the driest site, and the mean annual temperature increased along this gradient from 8.5 to 9.1 °C (Table 1).
«Indeed it is estimated that annual mean temperature has increased by over 2 °C during the last 70 years and precipitation has decreased in most regions, except the western part of the country, indicating that Mongolia is among the most vulnerable nations in the world to global warming.»
During the last century, mean precipitation in all four seasons of the year has tended to decrease in all the main arid and semi-arid regions of the world, e.g., northern Chile and the Brazilian North - East, West Africa and Ethiopia, the drier parts of Southern Africa and Western China (Folland et al., 2001).
