Prolonged absence or marked deficiency of precipitation (rain).
Drought is a deficiency of moisture that results in adverse impacts on people, animals, or vegetation over a sizeable area. NOAA together with its partners provides short- and long-term Drought Assessments.
a long period of dry weather when there is not enough water....... back
Condition in which an area does not get enough water because of (1) lower-than-normal precipitation or (2) higher-than-normal temperatures that increase evaporation.
An insufficient supply of moisture from precipitation or soil for optimum plant growth.
An abnormally long period of insufficient rainfall. Can cause the failure of crops, reduction in natural vegetation and depletion of water supplies.
A prolonged dry period resulting in crop damage.
An extended period of dry weather sufficiently prolonged for the lack of moisture to cause a serious hydrological imbalance (i.e. crop damage, water-supply shortage, etc.) in the affected area. (Source: Government of Canada Climate Change Site, Glossary of Climate Change Terms)
A deficiency of precipitation over an extended period of time.
Drought is viewed as a sustained and regionally extensive occurrence of below average natural water availability, either in the form of precipitation, river runoff, or groundwater. Droughts may be classified as meteorological or hydrological: A Meteorological Drought occurs when there is below average availability of precipitation. The National Meteorological Service (NMS) subdivides meteorological drought into three categories: drought, extreme drought, and severe drought. Drought is defined as less than 60% (range 41-60) of normal rainfall over 8 consecutive weeks. Extreme drought is defined as less than 40% (range 21-40) of the normal rainfall over 8 consecutive weeks. Severe drought is defined as less than 20% (range 0-20) of the normal rainfall over 8 consecutive weeks. The normal rainfall is the thirty year mean. A Hydrological Drought is marked by a deficit in the runoff of rivers where discharge (flow) remains below a low threshold or the rivers dry up completely and remain dry for a very long time and a significant natural depletion of aquifers (groundwater). The low threshold flow is the 10-year return period 7-day minimum mean flow.

A period of very dry weather.
a period of dryness especially when prolonged that causes extensive damage to crops or prevents their successful growth
A long period of unusually low rainfall resulting in parched ground and abnormal withering of vegetation. A drought is defined arbitrarily to suit the region. For example: a period of 4 months without rain would be regarded as a drought only if people were unprepared for it and it was not normal. However, in a desert region, a drought might be considered a succession of unusually dry years. From most perspectives drought is the norm on the prairies of North America.

(pronounced DROWT) an extended period during which the amount of rain or snow that falls on an area is much lower than usual.
The moisture deficit which results when the amount of water vapour available in the soil is not sufficient to meet the demand of potential evapotranspiration.
There is no definitive definition of drought based on measurable processes; scientists evaluate precipitation, temperature, and soil moisture data for the present and recent past to determine drought status. Very generally, it refers to a period of time when precipitation levels are low, impacting agriculture, water supply, and wildfire hazard.
Below average rainfall for an extended period of time.
Drought is a complex term that has various definitions, depending on individual perceptions. For the purposes of low water management, drought is defined as weather and low water conditions characterized by one or more of the following: -below normal precipitation for an extended period of time (for instance three months or more), potentially combined with high rates of evaporation that result in lower lake levels, streamflows or baseflow, or reduced soil moisture or groundwater storage -streamflows at the minimum required to sustain aquatic life while only meeting high priority demands for water, water wells becoming dry, surface water in storage allocated to maintain minimum streamflows -socio-economic effects occurring on individual properties and extending to larger areas of a watershed or beyond. As larger areas are affected and as low water and precipitation conditions worsen, the effects usually become more severe
extended period of time when a significant lack of moisture persists
A naturally-occurring phenomenon that occurs when precipitation is significantly below normal levels, causing water levels to drop and vegetation to die. This extended period of dry weather usually lasts longer than expected and leads to measurable losses for a human community (crop damage, water supply shortage).
a long period without any rainfall
A period of abnormally dry weather sufficiently long enough to cause serious effects on agriculture and other activities in the affected area.
A prolonged period of below-average precipitation.
period of little or no rain.
A prolonged period of less-than-normal precipitation such that the lack of water causes a serious hydrologic imbalance.
Climatic condition where water loss due to evaporation and transpiration is greater than water inputs through precipitation.
A period of relatively long duration with substantially below normal precipitation, usually occurring over a large area.
an extended period of dry weather that lasts longer than expected or than normal, and leads to measurable losses, such as crop damage or water supply shortages.
The prolonged lack of rain or availability of an adequate water supplies.
Generally, the term is applied to periods of less than average or normal precipitation over a certain period of time sufficiently prolonged to cause a serious hydrological imbalance resulting in biological losses (impact flora and fauna ecosystems) and/or economic losses (affecting man). In a less precise sense, it can also signify nature's failure to fulfill the water wants and needs of man.
a period of dryness which if lasts for a long period of time can cause damage to crops or a shortage of water.
a prolonged period with little or no rainfall
Dry weather, lack of rain
Droughts are merely temporary abnormalities determined by deficient precipitation and depend on the area in question. In one area of the world a drought may be a week without rain, while in drier parts of world like the American Southwest, it might be an annual rainfall deficit of less than four inches.
a period of time with dry weather and no rain
A long spell of dry weather resulting in a serious water shortage.
a period of abnormally dry weather sufficiently prolonged for the lack of water to cause a serious shortages of water for agriculture and other needs in the affected area
is a period of abnormal dryness for a particular region.
A long period with little or no rain.
Abnormally dry weather in a region over an extended period.
A prolonged period of dry weather sometimes defined by a precipitation less than 75% of average.
A period of deficient precipitation or runoff extending over an indefinite number of days, but with no set standard by which to determine the amount of deficiency needed to constitute a drought. Thus, there is no universally accepted quantitative definition of drought; generally, each investigator establishes his own definition.
Long periods of time when little or no rain falls.
a period when it rains less often than usual
A long period of time without rainfall
a period during which there is a water shortage.
prolonged dry weather generally when precipitation is less than 75% of the average.
(Sometimes spelled drouth.) A period of abnormally dry weather sufficiently long enough to cause a serious hydrological imbalance. Drought is a relative term, therefore any discussion in terms of precipitation deficit must refer to the particular precipitation-related activity that is under discussion. For example, there may be a shortage of precipitation during the growing season resulting in crop damage ( agricultural drought), or during the winter runoff and percolation season affecting water supplies ( hydrological drought). Compare dry spell; see absolute drought, partial drought.
Prolonged and abnormal shortage of water caused by lack of rainfall.
Abnormal dry weather for a specific area that is sufficiently prolonged for the lack of water to cause serious hydrological imbalance.
A drought is a period of time when there is not enough water to support agricultural, urban or environmental water needs. A drought usually refers to an extended period of below-normal rainfall, but can also be caused by drying bores or lakes, or anything that reduces the amount of liquid water available. Although what is considered "normal" varies from one region to another, drought is a recurring feature of nearly all the world's climatic regions.
In sports, a drought refers to instances in which a team has gone a lengthy period of time without accomplishing some goal (e.g. making the playoffs or winning a championship). Droughts occur for a variety of reasons, from chronic mismanagement to bad luck. Some fans believe that their team's drought is the result of a curse.
