Sentences with phrase «hydrologic drought»

Yohe and colleagues from Massachusetts Institute of Technology, and Industrial Economics Inc say that they are highly confident that impacts caused by hydrologic drought — on agriculture and water availability, for example — will be increasingly negative and widespread over time, despite persistent uncertainty about projected precipitation patterns.

► Agricultural drought relates to moisture deficits in the topmost 1 meter or so of soil (the root zone) that affect crops, ► meteorological drought is mainly a prolonged deficit of precipitation, and ► hydrologic drought is related to below - normal stream flow, lake and groundwater levels.

Together, the Colorado River flow, Southwest DAI, and southern Colorado Plateau temperature reconstructions allow an assessment of the covariation of hydrologic drought with annual maximum temperatures, AD 762 — 1996.

Also, he should define what he means by «climate change» in terms of time and space scales, and of what specific societally and environmentally relevant metrics (such as hydrologic drought; agricultural drought; large basin river floods, etc) he is focusing on.

meteorological drought — lack of precipitation agricultural drought — lack of soil moisture, or hydrologic drought - reduced streamflow or groundwater levels reservoir or reserve drought — lack of sufficient water in reservoirs to meet human needs or historical dry periods; a water deficiency

Have a look at the US Geological Survey graphic (pictured) in which the color brown denotes severe hydrologic drought - dried up streams and wells in other words.

Droughts can be broadly categorized into four groups: meteorological droughts (deficit in precipitation), agricultural droughts (deficit in soil moisture), hydrologic droughts (deficit in runoff and / or groundwater resources), and socio - economic droughts (higher demand than the available supply).

A complex interplay of climate, hydrologic and ecosystem processes, and human impacts influences drought.

Overall, consistent with the findings of Huntington (2006), the evidence for increases in both severe droughts and heavy rains (Section 3.8.2) in many regions of the world makes it likely that hydrologic conditions have become more intense.

Here's the problem forests and forest managers face under climate change: Increasing global mean temperatures, changes in precipitation, and the hydrologic cycle are expected to lead to temperature and drought stress for many tree species.

I can not envision physically that the hydrologic cycle can intensify and there not be an increase in storm frequency and intensity of floods and droughts.

Note also that there appears — already started — to be a likely increase in drought frequency with atmospheric warming and associated acceleration of the hydrologic cycle, assuming continued greenhouse gas emissions.

The school will also teach the importance of understanding the physical mechanisms that produce many of the most impactful extreme events, including «complex» hydrologic extremes such as drought and the role of coupled land - atmosphere feedback mechanisms in amplifying extreme temperature events.

Even though these gains were substantially less than runoff gains during pluvials, additional runoff under drought conditions could help lessen the impact of predicted climate - driven losses in hydrologic connectivity important to native fish in the Salt and Verde watersheds [64].

The combination of precipitation deficits and high temperatures has resulted in hydrologic conditions in some areas that match if not exceed the severity of the 1950s drought (Figs. 3B and 4).

Like any other region of the world, the state is subject to extreme hydrologic events, including both floods and droughts.

The hydrologic cycle will change and intensify, leading to changes in water supply as well as flood and drought patterns.
