drought

n. lack of rain, abnormally dry weather

A drought is an extended period of months or years when a region notes a deficiency in its water supply. Generally, this occurs when a region receives consistently below average precipitation. It can have a substantial impact on the ecosystem and agriculture of the affected region. Although droughts can persist for several years, even a short, intense drought can cause significant damage and harm the local economy.

Drought, Drouth A cyclic condition of the earth's astral light reacting upon the atmosphere and cooperating with other meteorological causes bringing about periods of dryness over larger or smaller portions of the earth; in extreme form, it brings about a state of periodic ekpyrosis or burning, resulting in the reduction of fertile areas into deserts. The opposite of this condition, resulting in extraordinary rains and floods of longer duration, and sometimes extending over wide surfaces of the earth, is called cataclysm. The dragon is said by the Chinese to be able to affect climate, producing droughts, rain, etc., a direct reference to the astral light in its cyclic workings upon earth; in history, the human application of the dragon is made to magicians of the fourth or early fifth root-race. Samael, Satan, or the Red Dragon, the Simoom, and the Vedic Vritra are drought producers, as is the Babylonian Tiamat, the dragon slain by Bel or by Merodach.
