What are the pros of a drought?
The benefits are significant: less effluent to the sea, less pollution into rivers, greater water security, tighter control on commercial and industrial outflows, more training and jobs for water technicians and developing understanding of groundwater recharge implications.
What are the disadvantages of droughts?
Examples of drought impacts on society include anxiety or depression about economic losses, conflicts when there is not enough water, reduced incomes, fewer recreational activities, higher incidents of heat stroke, and even loss of human life. Drought conditions can also provide a substantial increase in wildfire risk.
What are three characteristics of a drought?
The characteristics of droughts are expressed in terms of: (1) drought index, (2) intensity-duration-frequency. A drought index assimilates thousands of data on rainfall, snowpack, streamflow and other water-supply indicators into a comprehensible picture.
Can El Nino cause drought?
El Niño and La Niña affect not only ocean temperatures, but also how much it rains on land. Depending on which cycle occurs (and when), this can mean either droughts or flooding. Typically, El Niño and its warm waters are associated with drought, while La Niña is linked to increased flooding.
What are 3 effects of El Nino?
Severe drought and associated food insecurity, flooding, rains, and temperature rises due to El Niño are causing a wide range of health problems, including disease outbreaks, malnutrition, heat stress and respiratory diseases.
What is the relationship between El Nino and drought?
One such phenomenon is the periodic occurrence of El Niño. During El Niño episodes the normal patterns of tropical precipitation and atmospheric circulation are disrupted, hence triggering extreme climate events around the globe: droughts, floods and affecting the intensity and frequency of hurricanes.
Does El Nino cause more rain?
El Niño is a weather pattern that occurs in the Pacific Ocean. During this time, unusual winds cause warm surface water from the equator to move east, toward Central and South America. El Niño can cause more rain than usual in South and Central America and in the United States.
Where does El Nino affect the most?
Although El Niño has the most direct impacts on life in the equatorial Pacific, its effects propagate north and south along the coast of the Americas, affecting marine life all around the Pacific.
What are two effects of El Nino?
(i) The presence of the EL-Nino leads to an increase in sea-surface temperatures. (ii) It weakens the trade winds in the regions and causes heavy rainfall, floods or droughts in different regions of the world.
Is La Nina dangerous?
Extreme La Niña events are known to cause disastrous floods in the northern parts of Australia. For example, following the strong La Niña events in 2010, Queensland, Australia, experienced the worst floods ever. As a result of this catastrophic event, over 10, 000 people were displaced and forced to evacuate.
