Not exact matches

In addition, strong biosphere - radiation feedbacks are often present in several moderately wet regions, for instance in the Eastern U.S. and in the Mediterranean, where precipitation and radiation increase vegetation growth.

We found that where temperature and precipitation are increasing together, climates are changing faster than the temperature trend alone would suggest.»

There were no significant trends in mean annual total precipitation or total precipitation affected area but we did observe a significant increase in mean annual rain - free days, where the mean number of dry days increased by 1.31 days per decade and the global area affected by anomalously dry years significantly increased by 1.6 % per decade.

Interestingly, East Africa is one region where IPCC models predict precipitation increases for the coming century.

How does CO2 increase affect the water vapor exchange, the cloud amount and its incredibly complex feedbacks involving aerosols, precipitation efficiency, and the resultant radiation balance at the 1 - 2 meter height thermometer shelters where humanity defines his / her climate?

Taking the slow increase of precipitation with temperature as a given, the more rapid increase of boundary layer humidity implies that the rate of transport of moisture from the boundary layer to higher levels where it rains out must go down.

If you were in a situation where there was initially more precipitation than radiative cooling could handle, then the atmosphere could just warm up until the radiative cooling increased — though then you'd have to worry about how much the warming affects precipitation, etc..

Further, let's agree that this will on average cause more precipitation due to increased evaporation at these higher temperatures (the best data I have seen say that the precipitation trend over the continental US — where we have the best long term records — is up 5 - 10 % over the last century).

About item (1), the amounts which melt and refreeze in the Arctic give an impression of the relative amounts involved, where an increase of precipitation is marginal, compared to the the masses involved.

Growing populations and changing precipitation patterns will increase competition among urban, industrial, agricultural, and natural ecosystem water needs in regions where overall water supply declines.

As a consequence, even in regions or states where there is a strong increasing trend in heavy precipitation, the trend at an individual precipitation gauge that represents the official total for a city may be equivocal, flat, or even down.

«So where is the discussion of reverse solubility, increased physical precipitation and out gassing of Arctic and Antarctic oceans?»

Pakistan is in a region where temperature increases are higher, which will affect precipitation and vegetation.

Even in areas where precipitation does not decrease, these increases in surface evaporation and loss of water from plants lead to more rapid drying of soils if the effects of higher temperatures are not offset by other changes (such as reduced wind speed or increased humidity).5 As soil dries out, a larger proportion of the incoming heat from the sun goes into heating the soil and adjacent air rather than evaporating its moisture, resulting in hotter summers under drier climatic conditions.6

Nonetheless, in much of the United States where spring snow melt does not dominate peak or normal flow, Groisman et al. (2001) show increasing high streamflow related to increasing heavy precipitation.

Even where increases are projected, there can be short - term shortages due to more variable streamflow (because of greater variability of precipitation), and seasonal reductions of water supply due to reduced snow and ice storage.

Where precipitation decreases were projected, the results were more complex due largely to interactions between plant biomass, runoff, and erosion, and either increases or decreases in overall erosion could occur.

Efforts to offset declining surface water availability due to increasing precipitation variability will be hampered by the fact that groundwater recharge will decrease considerably in some already water - stressed regions (high confidence)[3.2, 3.4.2], where vulnerability is often exacerbated by the rapid increase in population and water demand (very high confidence)[3.5.1].

In addition to direct crop damage from increasingly intense precipitation events, wet springs can delay planting for grain and vegetables in New York, for example, and subsequently delay harvest dates and reduce yields.67 This is an issue for agriculture nationally, 65 but is particularly acute for the Northeast, where heavy rainfall events have increased more than in any other region of the country (Ch.

Projections of future changes in precipitation show small increases in the global average but substantial shifts in where and how precipitation falls.

We don't know how much climate change will be caused by X amount of CO2, nor how much of that climate change will manifest as increased precipitation, and where.

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.

Widespread increases in heavy precipitation events have been observed, even in places where total amounts have decreased.

As temperatures rise, the likelihood of precipitation falling as rain rather than snow increases, especially in autumn and spring at the beginning and end of the snow season, and in areas where temperatures are near freezing.

As for the 2006 study, it goes on to say: «The main exception is the Southwest and parts of the interior of the West, where, notwithstanding increased precipitation (and in some cases increased soil moisture and runoff), increased temperature has led to trends in drought characteristics that are mostly opposite to those for the rest of the country especially in the case of drought duration and severity, which have increased.»

That's the case in Antarctica, which is geographically very different to the Arctic, where an increase in surface sea ice area, but not total volume, is currently being observed due to increased precipitation and increased surface water run off.

In some regions where winter precipitation is projected to increase, the increased snowfall can more than make up for the shorter snow season and yield increased snow accumulation.

Anthropogenic influences have contributed to observed increases in atmospheric moisture content in the atmosphere (medium confidence), to global - scale changes in precipitation patterns over land (medium confidence), to intensification of heavy precipitation over land regions where data are sufficient (medium confidence), and to changes in surface and subsurface ocean salinity (very likely).

I have spent most of my life in very dry areas of Africa, where increased precipitation of that order would be most welcome, as also where I now live in Australia.

The differences are very small over most regions (less than ± 5 %), except for a small area of the equatorial Pacific Ocean, where the non-high-end models project an increase in precipitation that is about 50 per cent greater than in the high - end models.

The light green colour areas show where one or more models project a temperature rise of at least 6 °C, and at least 66 % of the models project a precipitation increase.

Droughts due to declines in precipitation are expected in the Mediterranean basin, as already mentioned, and in parts of India, where increasing temperatures are also expected to challenge the heat tolerances of rice and wheat crops.

The light green areas show where one or more models project a temperature rise of at least 6 °C, and at least 66 per cent of the models project a precipitation increase.

The largest increase in precipitation will occur over land in the tropics where the atmosphere is warming quickest.
