Droughts occur mainly in areas where normal levels of rainfall are, in themselves, low. If these factors do not support precipitation volumes sufficiently to reach the surface over a sufficient time, the result is a drought.
Where does a drought most likely occur?
Meteorologists predict drought based on precipitation patterns, stream flow, and moisture of soil over long periods of time. [4] In the United States, droughts are most likely to occur in the Midwest and the South.
More affected countries, which carry a medium to high risk of droughts, can be found in the Middle East, North Africa, Asia – including India and China – and Europe. Ukraine and its smaller neighbor have been hit by devastating droughts in the past, which majorly diminished crops.
What can cause droughts?
This is because a large region of volcanic rock now known as the Siberian Traps erupted within a couple million years of Kellwasser. It spewed out 240,000 cubic miles of lava and released sulfur dioxide into the atmosphere, which can cause acid rain.
Moreover, what is a drought and what causes it?
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.
What is drought, its types, causes and effects?
What is Drought, its types, causes and effects. TYPES OF DROUGHT. Agricultural drought : this is type of drought in which the moisture level in the atmosphere minimizes which in turn affects the soil moisture. CAUSES OF DROUGHT. Low rainfall : the main reason for drought is low or lack of rainfall.
Moreover, 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.
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.
