  - occur in places such as Australia, Indonesia, and southern Africa
* can be just as severe as rainfall intensities
  - meteorological, agricultural, hydrological, or socioeconomical

  - happen just about anywhere in Australia, but their severity is relative
  - impact an island over the long term, rather than immediately
  - lead to wildfires that burn vast areas of forest
* cans have impact
  - serious impact
* cause changes to ecosystems
  - famines and floods cause death and disease
* causes a desire to water plants
  - damage
  - famine, which contributes to decentralization and unrest
  - low soil moisture levels, creating ultra-dry brush that catches fires easily
  - plants to shut down their growth process
  - reductions
  - shortages of local food production
  - the water table to drop, heavy rains cause it to rise
* changes patterns
  - weather patterns
* continue to occur over many parts of the globe in varying degrees of severity and duration.
  - ideal conditions
* decreases growth, producing a narrower ring
  - the availability and abundance of the natural food supply
* deeply affects the land, water, and people of the Southwest.
* encourage locusts and rodents, while floods foster fungi and mosquitoes.
* exacerbate tensions over land and water use.
* exacerbates the problem of ensuring a sustainable yield of potable water.
* have at least two direct impacts on farmers and ranchers.
* historically occur in the region in cycles.
* impacts the frequency and the severity of forest fires by setting up ideal fire conditions.
* increase the potential for wildland fires.
  - nitrate concentration in plants
* increases the chance for high levels of prussic acid in plants
  - of winterkill by reducing the volume of water in the lake
  - rate of natural die-off of plant roots
* induces oxidative stress in pea plants.
* is capable of last years
  - most severe in Florida
  - natural hazards
  - probably the most important factor controlling crop yield worldwide
  - time periods
* kills mature trees
* occur every few years and with that comes malnutrition
  - frequently
  - from time to time and sometimes result in famine
* occur in Indonesia, Australia, and Africa
  - other, normally moist areas
  - regularly in the habitats occupied by the southern hairy-nosed wombat
  - when a long period passes without substantial rainfall
* occurs in Indonesia, the Philippines and Australia
  - when transpiration exceeds the plant's ability to supply water through the roots
* often results in a culling of older and infirm horses
  - mass displacements of population
  - stalks trees with little if any notice Falling limbs came first
* portends dangerous and long fire seasons throughout much of the United States.
* poses serious hazards to human and wildlife populations in many parts of the world.
* produces famine and disease.
* recur frequently and cause cyclic changes in the flora and fauna of the region.
* reduce or destroy the maize crop.
* reduces habitat quality
* refers to a lack of precipitation over an extended time period.
* regenerates the soil, producing healthier wetlands once the region again becomes wet.
* results in loss reductions
* still happen, and when they do, babies as well as adults die.
* stresses pearl millet, causing nitrate levels to be higher than normal.
* take their toll on trees.
* tend to do their worst on land that is already arid, and where societies are on the margin
  - drive communities apart
* threatens both crop and livestock production.
* usually take a season or more to develop.
* vary in length and intensity, and either factor can have a devastating economic impact.
+ Desertification, Causes: Environmental issues
  * The distribution of rainfall in the surrounding area of desert is uneven. From 1970 onwards, the world's weather has been changing. There has been less rain, and the world is becoming more dry. Drought affects the area surrounding. As a result, many crops and animals have died. There is no vegetation to protect the soil. The topsoil is removed by sudden flash floods or strong wind. This makes the soil erode and the desert spread towards the surrounding area.
+ Sunspot, Their effect on Earth: Weather :: Solar System :: Astrophysics
  * Sunspots are cooler than the rest of the sun, but many scientists think that when there are a lot of sunspots, the sun actually gets 'hotter'. This affects the weather here on Earth, and also radio reception. Without sunspots the earth would probably be cooler. In the same way, if there were too many sunspots, the earth would get really hot, and there would not be a lot of rain. This would make lots of  on the Earth. Droughts are a long time with no rain. People need rain to live. The food we eat can not grow without a lot of rain. A drought can be a very dangerous thing. The sunspots help keep Earth the right temperature. This is cold when compared to other areas on the surface of sun.

  * Rainfall is usually low, very hard to predict. Climate statistics for Australian locations'. Australian Government, Bureau of Meteorology. Retrieved 16 March 2012. Rain is most common between November and March. Droughts are common and can be very long. The most rain recorded in one year was  in 1974. The least amount was  in 1965. The year 1965 was also the end of the longest drought that has been recorded here, which lasted six and a half years. They are very important for refilling the groundwater supply and can put a lot of life into the ecosystems. The last major rainfall was in 2009, which got  of rain.
