Drought is a gradual phenomenon, occurring slowly over a period of time.
Drought can have even more far-reaching impacts when it affects a region that supplies agricultural products …
A drought is a lengthy period of time, stretching months or even years in which time; land has a decrease in water supply. A drought is a stage during which farmers are urgently waiting for rain because the soils run dry. A drought can be declared in as little as 15 days, and drought can be the result of water shortages in ground water, surface water, or even atmospheric water. The end of a drought is hard to identify for the same reason.
Storage, whether in surface water reservoirs or in groundwater basins, buffers drought impacts and influences the timing of when drought impacts occur. A “drought” is an extended period of deficient rainfall relative to the statistical multi-year average for a region. Droughts can become dangerous to people and other land animals; causing famine and even creating deserts. It differs from the aforementioned types of drought because its occurrence depends on the time and space processes of supply and demand to identify or classify droughts. It occurs when evaporation and transpiration exceed precipitation for … More rain, sleet, hail, and snow can occur where there are moist, low-pressure air systems. http://www.discovery.com/news/features/drought/drought.html, http://www.riverdeep.net/current/2000/05/front.170500.drought.jhtml, http://www.ngdc.noaa.gov/paleo/drought/drght_home.html, http://www.state.nj.us/drbc/drought/kids_droughtinfo.htm, http://enso.unl.edu/ndmc/enigma/cchange.htm, http://www.dep.state.pa.us/dep/subject/hotopics/drought/drtterm.htm, http://www.tamiu.edu/cost/drought/impacts/index.htm, http://enso.unl.edu/ndmc/enigma/indices.htm, http://enso.unl.edu/ndmc/impacts/impacts.htm, http://www.usatoday.com/weather/whydro00.htm, http://lwf.ncdc.noaa.gov/oa/climate/research/dm/weekly-DM-animations.html, http://lwf.ncdc.noaa.gov/oa/climate/research/drought/drought.html, http://www.cpc.ncep.noaa.gov/products/analysis_monitoring/regional_monitoring/palmer.gif, http://www.cpc.ncep.noaa.gov/products/expert_assessment/seasonal_drought.html, http://www.sandwich.k12.ma.us/webquest/drought/index.htm, http://library.thinkquest.org/10136/drought/droutq.htm, http://library.thinkquest.org/16132/html/drought.html, http://library.thinkquest.org/C003603/english/droughts/whatsadrought.shtml, http://www.germantown.k12.il.us/html/droughts1.html, http://www.wm.edu/wmnews/042398/drought.html, http://www.pbs.org/saf/1203/features/climatology.htm, http://www.disasterrelief.org/Disasters/000210megadrought/, http://www.ngdc.noaa.gov/paleo/drought/drght_james.html, http://www.watershedradio.org/may2001/050301roano.htm, http://www.bayjournal.com/current/trees.htm, http://www.ngdc.noaa.gov/paleo/drought.html, http://www.pbs.org/wgbh/amex/dustbowl/index.html, http://newdeal.feri.org/library/7_31_4r.htm, http://www.utahhistorytogo.org/drought.html, http://www.ultranet.com/~gregjonz/dust/dustbowl.html, http://enso.unl.edu/ndmc/impacts/dustbowl/1930s1.htm, http://pigtrail.uark.edu/news/2002/FEB02/Stahle02.html, http://www.abqjournal.com/2000/1mill5-27.htm, http://www.santafe.edu/~johnson/articles.anasazi.html, http://www.learner.org/exhibits/collapse/chacocanyon.html, http://www.usatoday.com/weather/science/archaeology/anasazi102900.htm, http://www.cpluhna.nau.edu/People/paleoenvironmental_change.htm, http://www.ncdc.noaa.gov/climvis/usdroughthistory.html, http://twri.tamu.edu/twripubs/WtrResrc/v22n2/index.html, http://twri.tamu.edu/twripubs/WtrResrc/v22n2/text-3.html, http://www.time.com/time/special/drought/, http://www.cgiar.org/iwmi/home/drought.htm, http://www.fao.org/waicent/faoinfo/sustdev/EPdirect/EPan0005.htm, http://www.redcross.org/services/disaster/keepsafe/drought.html, http://www.dep.state.pa.us/dep/subject/hotopics/drought/default.htm, http://www.dola.state.co.us/oem/PublicInformation/Drought/drought.htm, http://aggie-horticulture.tamu.edu/PLANTanswers/drought/drought.html, http://www.dca.state.fl.us/bpr/EMTOOLS/florida_drought_center.htm, http://www.state.ok.us/~governor/drought.htm, http://water.dnr.state.sc.us/climate/sco/drought.html, http://www.wrds.uwyo.edu/wrds/wsc/dtf/drought.html, http://www.oneworld.org/ips2/aug00/17_53_028.html, http://www.bom.gov.au/climate/drought/livedrought.shtml, http://www.usaid.gov/press/releases/2002/fs020510.html, http://www.uregina.ca/biology/faculty/leavitt/drought/drought1.htm, http://www.oxfam.org.uk/coolplanet/ontheline/schools/swallows/drought.htm, http://www.riverdeep.net/current/1999/08/080299.drought.jhtml, http://school.discovery.com/schoolfeatures/featurestories/earthalert/drought/, http://fyi.cnn.com/2002/fyi/lesson.plans/06/13/wildfire/, http://www.worldwatcher.northwestern.edu/userdownloads/pdf/lessonsamples.pdf, http://www.nationalgeographic.com/xpeditions/lessons/01/g35/drought.html, http://interactive2.usgs.gov/learningweb/teachers/globalchange_time.htm, disaster, This can happen at any given time, even in winter time, however, for most droughts, they do occur during warmer or drier months.
Droughts affect people in a several ways.
Droughts occur when there is abnormally low rainfall for an extended period of time. The most important one though relates to the amount of water vapor in the atmosphere as this is what creates precipitation. The supply of many economic goods, such as water, forage, … Sometimes, drought conditions can exist for a decade or more in a region. Droughts are slowly emerging over time. Drought is a continuous period of dry weather, when an area gets less than its normal amount of rain, over months or even years.
What’s the link between climate change and drought?
Crops and other plants need water to grow, and animals need it to live. Drought and floods leave millions in need of urgent life-saving help.
Droughts are the second-most costly weather events after hurricanes. Find out the key facts in this post.
Causes . The longer a drought lasts, the greater the harmful effects it has on people.
catastrophe & calamity. Harder - A drought, pronounced drowt, is a period of abnormally dry weather when the average rainfall for a region drops far below the normal amount for a long time. A drought may last for weeks, months, or even years.
Drought, lack or insufficiency of rain for an extended period that causes a considerable water imbalance and, consequently, water shortages, crop damage, streamflow reduction, and depletion of groundwater and soil moisture.
Droughts are one of the worst natural disasters to occur.
Droughts have the ability to harm more than just the agriculture and ecosystem of the region, but also the economy of those living in the region. The rivers have low water levels and the vegetation turns its color from green to yellow during the period of the growing season. Massive drought across Great Plains could cost farmers up to $1bn. Environment. A single dry year isn’t a drought for most Californians because the state’s extensive system of water infrastructure and groundwater resources buffer impacts.
Easier - A drought is a long period of very dry weather.It is a long time with little or no rain. And it’s not surprising – droughts have been drier and lasting longer in recent years thanks in part to climate change.
Socioeconomic definitions of drought associate the supply and demand of some economic good with elements of meteorological, hydrological, and agricultural drought.
But because of the various ways it is measured, an objective drought definition has yet to be produced upon which everyone can agree. Americas. Because drought is defined as a deficit in water supply, it can be caused by a number of factors. Of all the ways climate change inflicts harm, drought is the one people worry about most, according to a Pew Research Center survey. The lack of adequate precipitation, either rain or snow, can cause reduced soil moisture or groundwater, diminished stream flow, crop damage, and a general water shortage.
period of unusually dry weather that persists long enough to cause problems such as crop damage and water supply shortages A drought is a period of time when an area or region experiences below-normal precipitation.
