The Water Cycle: The movement of water through the water cycle, from evaporation and transpiration to condensation, to water storage in the atmosphere, to precipitation, to water storage in ice and snow, surface runoff, snowmelt runoff to streams, streamflow, and freshwater storage linux kostenlos deutsch. A cut away shows the ground water portion of the water cycle, from infiltration to ground water storage and ground water discharge into springs and freshwater storage herunterladen. Surface runoff, freshwater storage, ground water storage, and ground water discharge are all shown contributing to water storage in oceans, where the evaporation portion of the water cycle starts again icloud fotosen windows 10.
The movement of water between the land surface, oceans and atmosphere is called the hydrologic cycle 64 bit or 32 bit. Water in the atmosphere is transported to the land surface and oceans as precipitation (rain, snow or sleet). Upon reaching the land surface, water may immediately become streamflow, or it may infiltrate into the soil where it may later be taken up by plants or it can percolate to the groundwater herunterladen. Surface streamflow and groundwater flow move water from the land surface to lakes and the ocean. Water re-enters the atmosphere as vapor either via evaporation from surface waters (ocean, lakes, etc) or transpiration from plants herunterladen. This cyclical movement of water is driven by solar energy. An increase in net solar radiation or temperature will effectively speed up the processes within this cycle kinder hörbücher kostenlos downloaden mp3.
Due to complex interactions of changes in the hydrologic cycle with global circulation patterns and local weather patterns, an increase in energy in the hydrologic cycle does not necessarily translate into an increase in precipitation in all geographic regions Keepass 2. It is difficult to predict future changes in regional precipitation patterns. Predicting regional changes in streamflow and groundwater recharge due to climate change also remains challenging, particularly because of the uncertainty in regional projections of how precipitation may change videos from orf tvthek.
Changes in temperature, precipitation patterns and snowmelt can have impacts on water availability. Temperature is predicted to rise in most areas, but is generally expected to increase more in inland areas and at higher latitudes herunterladen. Higher temperatures will increase loss of water through evaporation. The net impact on water supplies will depend on changes in precipitation (including changes in the total amount, form, and seasonal timing of precipitation). Generally speaking, in areas where precipitation increases sufficiently, net water supplies may not be affected or they may even increase. In other areas where precipitation remains the same or decreases, net water supplies would decrease. Where water supplies decrease, there is also likely to be an increase in demand, which could be particularly significant for agriculture (the largest consumer of water) and also for municipal, industrial and other uses.
Increases in temperature can affect the amount and duration of snow cover which, in turn, can affect timing of streamflow. Glaciers are expected to continue retreating, and many small glaciers may disappear entirely. Peak streamflow may move from late spring to early spring/late winter in those areas where snowpack is important in determining water availability. Changes in streamflow have important implications for water and flood management, irrigation, and planning. If supplies are reduced, off-stream users of water such as irrigated agriculture and in-stream users such as hydropower, fisheries, recreation and navigation, could be most directly affected.
