Drought in general means acute water shortage. The drought maps highlight areas considered to be suffering from a serious or severe rainfall deficiency.
Drought Assessments - At the end of each month, CPC issues a long-term seasonal drought assessment.
Drought - a period of abnormally dry weather sufficiently prolonged for the lack of water to cause serious shortages of water for agriculture and other needs in the affected area ...
drought: a long period of time where there is abnormally dry weather due to little or no precipitation.
DROUGHT Abnormal dry weather for a specific area that is sufficiently prolonged for the lack of water to cause serious hydrological imbalance.
Drought
A prolonged absence or marked deficiency of precipitation.

Drought - an extended period of dry weather.
Dust Devil - A small atmospheric vortex not associated with a thunderstorm, which is made visible by a rotating cloud of dust or debris (dust whirl).
Drought A period of abnormally dry weather sufficiently long enough to cause serious effects on agriculture and other activities in the affected area.
Drought Index Computed value which is related to some of the cumulative effects of a prolonged and abnormal moisture deficiency. (An index of hydrological drought corresponding to levels below the mean in streams, lakes, and reservoirs.).
Drought- Abnormally dry weather in a region over an extended period sufficient to cause a serious hydrological (water cycle) imbalance in the affected area. This can cause such problems as crop damage and water-supply shortage.
Palmer Drought Severity Index"(Abbreviated PDSI.) An index formulated by Palmer (1965) that compares the actual amount of precipitation received in an area during a specified period with the normal or average amount expected during that same ...
PALMER DROUGHT INDEX A long-term meteorological drought severity index produced by the NOAA/USDA (Department of Agriculture) Joint Agricultural Weather Facility.
Palmer Drought Severity Index
(Abbrev. PDSI) - an index used to gage the severity of drought conditions by using a water balance equation to track water supply and demand. This index is calculated weekly by the National Weather Service.
Palmer Drought Severity Index: An index whereby excesses or deficiencies of precipitation are determined in relation to average climate values.

The Jet Stream Changed Course.
The jet stream normally flows west over the Gulf of Mexico and turns northward pulling up moisture and dumping rain onto the Great Plains.

Droughts in the Western Pacific Islands and Indonesia as well as in Mexico and Central America were the early (and sometimes constant) victims of this El Niño. These locations were consistent with early season El Niños in the past.

Droughts- Long periods of low precipitation.
El Niņo- An event that occurs every two to seven years in the Pacific Ocean, during which winds shift and push warm surface water towards the coast of south America; it can cause dramatic climate changes.
Drought - A period when a region has a lack of rainfall. Droughts can affect a fairly small area for a season or an entire continent for years. Too little rainfall can cause shortages in the water supply, destroy crops, and cause widespread hunger.
Drought- Abnormally dry weather in a region over an extended period.
Dust Devil- A small, whirling column of wind that picks up dirt and other loose material as it travels.
Drought - an extended period of dry weather.
Dry Adiabat - A line of constant potential temperature on a thermodynamic chart. See Fig. 6, sounding.
DROUGHT - A lengthy period with little or no precipitation. Droughts cause a water defecit and can kill plants and wildlife, especially through higher incidences of fires.
Keetch-Byrum Drought Index
An index used to gage the severity of drought in deep duff and organic soils.
Kelvin Temperature Scale ...
DroughtDrought 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.
As part of its mission, the USGS provides information and data on the Nation's rivers and streams that are useful for mitigation of hazards associated with floods and droughts.
water stress effect The closing of the stomata by a plant in response to excessive water loss through transpiration or in response to drought conditions.
Drier summers could lead to more periods of drought[21], potentially affecting many species of animal and plant. For example, in the UK during the drought year of 2006 significant numbers of trees died or showed dieback on light sandy soils.
