Question

1. describe how la niña affects the trade winds. in the powerpoint unusually warm surface water temperatures in the pacific ocean caused by weak (or reversed direction) easterly trade winds.
2. how does la niña affect pacific ocean temperatures?
3. how does el niño affect indonesia?
4. how has el niño impacted europe?
5. how does el niño affect north carolina?
6. how does la niña affect north carolina?

Explanation:

1. During La Niña, the trade - winds strengthen. Stronger easterly trade winds blow across the tropical Pacific, pushing warm surface water towards the western Pacific and allowing cold water to upwell in the eastern Pacific.
2. La Niña causes cooler - than - average sea - surface temperatures in the central and eastern tropical Pacific Ocean due to enhanced upwelling of cold water from the deep ocean as a result of stronger trade winds.
3. El Niño brings drought to Indonesia. The normal pattern of warm water in the western Pacific is disrupted, reducing the amount of convective activity and rainfall over Indonesia.
4. El Niño can impact Europe in various ways such as milder and wetter winters in some parts and changes in storm tracks, which can lead to more or less precipitation and different temperature patterns.
5. El Niño can lead to wetter conditions in North Carolina during the winter months. It can also affect the frequency and intensity of storms.
6. La Niña can lead to drier and colder conditions in North Carolina during the winter. It can also influence the hurricane season, potentially increasing the number of hurricanes that affect the region.

Answer:

1. During La Niña, easterly trade winds strengthen, pushing warm water west and upwelling cold water east.
2. La Niña causes cooler - than - average sea - surface temps in central and eastern tropical Pacific due to enhanced upwelling.
3. El Niño brings drought to Indonesia by disrupting normal warm - water pattern and reducing convective activity.
4. El Niño can cause milder, wetter winters and change storm tracks in Europe.
5. El Niño can lead to wetter winters and affect storm frequency/intensity in North Carolina.
6. La Niña can lead to drier, colder winters and potentially increase hurricane activity affecting North Carolina.
