Because drought is defined as a deficit in water supply, it can be caused by a number of factors. The most important one though relates to the amount of water vapor in the atmosphere as this is what creates precipitation. More rain, sleet, hail, and snow can occur where there are moist, low-pressure air systems.
Some have found that a drought is caused by drier than normal conditions that can eventually lead to water supply problems. Really hot temperatures can make a drought worse by causing moisture to evaporate from the soil. Just because a region is hot and dry doesn’t necessarily mean it is going through a drought.
The phenomenon where drought is experienced?
Drought occurs in high as well as in low rainfall areas. It is a condition relative to some long-term average condition of balance between rainfall and evapotranspiration in a par- ticular area, a condition often perceived as “ normal.” Yet average rainfall does not provide.
What are the causes and effects of drought?
Meteorological droughts occur when dry weather patterns dominate an area. Hydrological droughts refer to when low water supply becomes evident in the water systemAgricultural droughts happen when crops become affected by drought. Socioeconomic droughts occur when the supply and demand of various commodities is affected by drought., and more items.
What constitutes a drought and why it matters?
Weather and Climate. If you look outside right now, do you see sunshine, or mostly clouds? Water covers more than 80 percent of the earth’s surface. Water and Weather on the Move. Water evaporating from the oceans, lakes, rivers, and streams moves to the atmosphere. Causes of drought, drought and floods, or drought has many causes are a couple additional items to pay attention too.
How does drought affect our lives?
Who lives in the community, because some people are more affected by drought than others based on things like health conditions and age. What kind of water system the community has. What rules the community has about water use. Other economic and social factors.
What are facts about drought?
Grazing land is inadequate. Fire season is longer, with high burn intensity, dry fuels, and large fire spatial extent. Trees are stressed; plants increase reproductive mechanisms; wildlife diseases increase.
One inquiry we ran across in our research was “What are some interesting facts about droughts?”.
They are: Meteorological drought – that is caused by shortage of precipitation or rainfall. Agricultural drought – that is caused by lack of moisture in the soil. Hydrological drought – that is caused by low levels of water in various water sources like rivers, lakes, etc. Socioeconomic drought – that is caused by shortage of tap and drinking water.
