What impact does El Niño have on the fishing industry Brainly?

Answer Expert Verified

The answer is B. The reason behind this is that El Niño decreases the rate of upwelling of water on the coast. Upwelling occurs when cold, nutrient-rich water “wells up” from the surface. If this process is disrupted manly due to El Niño, the movement of marine life is also affected.

What impact does El Nino have?

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.

How does El Nino effect contribute to drought?

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.

How does El Nino affect ecosystems?

Ecosystems and human communities can be positively or negatively affected. For example, in the Southern United States, during the fall through spring, El Niño usually causes increased rainfall and sometimes destructive flooding. … Changes in ocean temperatures and currents that happen during El Niño impact marine life.

What is an El Niño Southern Oscillation event Brainly?

Answer: High sea surface temperature and High rainfall. Explanation: El Niño is a pattern of climate that causes the unusual warming of surface waters in the eastern part of the tropical Pacific Ocean. It affects the temperature of the ocean and changes the strength and speed of its currents, coastal.

What are the causes and effects of El Nino?

El Nino is essentially caused by the interaction between the surface layers of the tropical Pacific Ocean and the atmosphere over it. The water is warmer due to the trade winds reversing direction or becoming less intense.

Is El Nino good or bad?

It generates powerful high-altitude winds that cut the tops off of tropical storms before they can grow into hurricanes. Good or bad, scientists say that, aside from the seasons themselves, El Niño is the most powerful climate force on Earth.

Do humans cause El Nino?

As humans put more and more heat-trapping gases into the atmosphere, the Earth warms. And the warming is causing changes that might surprise us. Often times, neither an El Niño or La Niña is present and the waters are a normal temperature. …

Does El Nino cause more rain?

El Niño occurs when warm water builds up along the equator in the eastern Pacific. The warm ocean surface warms the atmosphere, which allows moisture-rich air to rise and develop into rainstorms. … During El Niño years, such as 1997, the southeast receives more rain than average.

Does El Nino or La Nina 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.

Does La Nina cause drought?

In the United States, for example, La Niña occurs for at least five months of La Niña conditions. … A usual, La Niña winter features drier and milder conditions across the Southern hemisphere. This causes elevated fire conditions and the Southeast drought conditions.

What are the causes and effects of El Nino and La Nina?

The changes in sea surface temperatures during El Niño and La Niña are caused and helped along by changes in the trade winds, which normally blow from east to west across the tropical Pacific Ocean. … Warm waters in the west Pacific Ocean slosh to the east.
