Sentences with phrase «of hydrological drought»

The researchers from Wageningen University & Research, Bogor Agricultural University in Indonesia, University of East Anglia and the Center for International Forestry Research analysed the spatially distributed pattern of hydrological drought, that is the drought in groundwater recharge, in Borneo using a simple transient water balance model driven by monthly climate data from the period 1901 - 2015.

This study highlights the importance of considering hydrological drought for wildfire prediction, and the researchers recommend that hydrology should be considered in future studies of the impact of projected ENSO strength, including effects on tropical ecosystems, and biodiversity conservation.

In hydrological data, there are series of 20 or 30 years, when we would need 100 years or more to see if there is a cycle of flooding and drought.»

The paradox is that this season stands in such stark contrast to the past 11 years of drought, highlighting the types of variability that climate change can wreak on the hydrological cycle.

This indicator has a profound meaning for the hydrological cycle and is relevant for the question of flood risk and droughts.

By the 2100 humankind could be looking at a very different world, 7 metres more water apparantly, a slowdown of the worlds thermohaline system which could plunge northern europe into some canada style winters, a major realignment of the planets hydrological cycle which would mean drought and monsoons where none exist now perhaps, the disapperance of the Amazon rainforest, more extreme el ninos that last a lot longer along with the sister efect (la nina I think.

Visible changes in hydrological cycle have been observed in the form of changing precipitation patterns, cropping patterns, droughts, water availability periods, frequency and intensity of heatwaves, precipitation events and weather - induced natural disasters.

The end of the first half of the Holocene — between about 5 and 4 ka — was punctuated by rapid events at various latitudes, such as an abrupt increase in NH sea ice cover (Jennings et al., 2001); a decrease in Greenland deuterium excess, reflecting a change in the hydrological cycle (Masson - Delmotte et al., 2005b); abrupt cooling events in European climate (Seppa and Birks, 2001; Lauritzen, 2003); widespread North American drought for centuries (Booth et al., 2005); and changes in South American climate (Marchant and Hooghiemstra, 2004).

with increasing stress on crops due to changes in the hydrological cycle and heat stress, more and more farmers are seeking answers from modified crops to heartier breeds of cattle that are more accustomed to drought conditions such as those that come from Africa and India.

More accurate and reliable precipitation data would be invaluable, not only for the study of climate trends and variability, but also as inputs to hydrological and ecological models and for model validation, characterization of extreme events, and flood and drought forecasting.

For example, hydrological drought is closely related to human activities, such as irrigation, thus accurate prediction necessitates the modeling of human activities.

These include increased average land and ocean temperatures that lead to reduced snowpack levels, hydrological changes, and sea level rise; changing precipitation patterns that will create both drought and extreme rain events; and increasing atmospheric CO2 that will contribute to ocean acidification, changes in species composition, and increased risk of fires.

The results have implications for how we interpret the impact of global warming on the hydrological cycle and its extremes, and may help to explain why palaeoclimate drought reconstructions based on tree - ring data diverge from the PDSI - based drought record in recent years9, 10.

Besides this study, there are robust theory and modeling results that show increased risk of hydrological extremes (floods and droughts) and heat - related problems.

Although the recent drought may have significant contributions from natural variability, it is notable that hydrological changes in the region over the last 50 years can not be fully explained by natural variability, and instead show the signature of anthropogenic climate change.

Managing hydrological impacts of simultaneously - occurring record El Niño and record drought in California will be challenging.

Risky Business in the Face of Climate Change Catastrophic flooding in Pakistan, dam breaks around the world, and drought - caused blackouts in Africa provide ample warning of how global warming is changing the hydrological cycle.

Drought - In general terms, drought is a «prolonged absence or marked deficiency of precipitation,» a «deficiency that results in water shortage for some activity or for some group,» or a «period of abnormally dry weather sufficiently prolonged for the lack of precipitation to cause a serious hydrological imbalance.»

Hydrological drought is based on both precipitation and temperature, which affect the amount of soil moisture.
