Meteorology: Global Weather Patterns, El Niño, and La Niña

What is the role of atmospheric circulation in weather patterns?

• It has no effect on weather patterns.

• It only affects temperature, not precipitation.

• Atmospheric circulation influences the distribution of temperature and precipitation, affecting weather patterns globally.

• It only impacts local weather, not global patterns.

What is the impact of La Niña on Indonesia?

• La Niña typically brings dry weather to Indonesia.

• La Niña typically brings wet weather to Indonesia.

• La Niña has no significant impact on Indonesia's weather.

• La Niña causes extreme heat waves in Indonesia.

What is the El Niño-Southern Oscillation (ENSO)?

• A phenomenon involving ocean-atmosphere interaction that includes the El Niño event and the Southern Oscillation occurring almost simultaneously.

• A weather pattern that only affects the Pacific Ocean region.

• A type of ocean current that flows from east to west across the equator.

• A seasonal change in wind patterns that occurs every summer.

How often does El Niño typically occur?

• Once every two years

• Once every four years

• Once every six years

• Once every eight years

What is a drought?

• A prolonged period of abnormally low rainfall totals, which can have significant effects on the biosphere.

• A sudden increase in rainfall leading to flooding.

• A seasonal change in weather patterns that causes heavy snowfall.

• A type of plant that thrives in dry conditions.

What are the potential consequences of a warming climate on El Niño and La Niña?

• A warming climate may enhance the effects of both El Niño and La Niña.

• A warming climate will completely eliminate El Niño and La Niña events.

• A warming climate has no impact on El Niño and La Niña.

• A warming climate will only affect El Niño, not La Niña.

What is the significance of temperature gradients in global circulations?

• They have no impact on weather patterns.

• They are the primary driving force in global circulations, influencing weather patterns.

• They only affect ocean currents, not atmospheric conditions.

• They are only relevant in local weather systems.

How does climate change affect El Niño and La Niña?

• Climate change has no effect on El Niño and La Niña.

• Climate change alters the factors influencing El Niño and La Niña, potentially leading to more severe episodes.

• Climate change only affects El Niño, not La Niña.

• Climate change makes El Niño and La Niña less frequent.

What is the effect of climate change on the frequency of droughts?

• Climate change has no effect on drought frequency.

• Droughts are becoming less frequent due to climate change.

• Droughts are lasting longer and increasing in frequency due to climate change.

• Climate change only affects rainfall, not droughts.

What are the effects of El Niño on global weather patterns?

• El Niño causes atmospheric temperature swings and changes in humidity, leading to wild weather, including hurricanes and flooding.

• El Niño results in a decrease in global temperatures and reduced rainfall in tropical regions.

• El Niño has no significant impact on global weather patterns and is a natural phenomenon that occurs without consequences.

• El Niño primarily affects ocean currents and has minimal effects on atmospheric conditions.
