Global Weather Patterns Activity Instructions: Read the information below answer the background information questions. Then, follow the instructions to convey your findings in a slideshow presentation. What Is ENSO? © 2016 NOAA Climate.gov El Nià±o and La Nià±a are recurring climate patterns across the tropical Pacific. Together they make up the El Nià±o-Southern Oscillation, or "ENSO" for short. ENSO is Earth's most influential natural climate pattern.

The pattern can shift back and forth irregularly every two to seven years and cause disruptions of temperature, precipitation, and winds. These changes disrupt the air movements in the tropics. During El Nià±o, there are warmer sea surface temperatures in the Pacific. This weakens the easterly winds. During La Nià±a, the sea surface temperatures are cooler than normal, and the easterly winds become stronger.

Answer the following questions: 1. What is El Nià±o? 2. What is La Nià±a? 3.

How do El Nià±o and La Nià±a differ? United States Impacts © 2016 NOAA Climate.gov By modifying the Pacific jet streams, El Nià±o and La Nià±a can affect temperature and precipitation across the United States. The influence on the U.S. is strongest during the Northern Hemisphere winter. This map shows typical impacts of La Nià±a on U.S. winter weather. These impacts have been associated with La Nià±a events in the past, but not all of these impacts happen during every La Nià±a episode.

Answer the following question: 4. Based on the wintertime La Nià±a weather map, what do you think Florida's temperature and precipitation would be like during a winter El Nià±o event? Global Impacts El Nià±o and La Nià±a have their strongest impact on global climate during the Northern Hemisphere winter and early spring. El Nià±o and La Nià±a are opposite patterns. El Nià±o warms, and La Nià±a cools large areas of the tropical Pacific, which influences where and how much it rains there.

This disrupts the atmospheric circulation patterns, which affect the mid-latitude jet streams. By modifying the jet streams, ENSO can affect temperature and precipitation across the United States and in other parts of the world. Answer the following question: 5.

Paper for above instructions


Slide One: Introduction


El Niño and La Niña are essential components of the El Niño-Southern Oscillation (ENSO), a significant climate phenomenon that impacts global weather patterns. El Niño refers to the warming of the sea surface temperatures in the central and eastern tropical Pacific Ocean, typically every two to seven years. This warming affects atmospheric circulation and leads to changes in wind patterns, precipitation, and temperatures across the globe. La Niña, conversely, refers to the cooling of sea surface temperatures in the same regions and results in stronger-than-normal easterly winds and altered climate patterns (NOAA, 2023).

Slide Two: Compare and Contrast


El Niño and La Niña exhibit contrasting characteristics that significantly influence climatic conditions.
- Temperature: El Niño is characterized by warmer than average sea surface temperatures, while La Niña is denoted by cooler conditions.
- Atmospheric Pressure: El Niño contributes to lower pressure in the eastern Pacific and higher pressure in the western Pacific, while La Niña exhibits the opposite pattern.
- Weather Patterns: During El Niño, many regions experience increased rainfall and higher temperatures, whereas La Niña typically leads to drier and cooler conditions in specific parts of the world.
This fundamental oscillation profoundly impacts global weather, including altering precipitation patterns and the frequency of extreme weather events (McPhaden et al., 2019).

Slide Three: Data Analysis


Examining the coastal region of Southeast Asia helps illustrate how El Niño and La Niña affect climate differently.
- During El Niño: Southeast Asia may experience drier conditions, leading to significant droughts, a decrease in water supply, and subsequent agricultural challenges. For example, Indonesia is often affected by lower rainfall, risking food security and causing adverse health impacts due to water shortages.
- During La Niña: The same region typically experiences increased rainfall, leading to flooding, landslides, and accompanying agricultural benefits as moist conditions can support crop growth.
This dichotomy underscores the variability of climate impacts due to ENSO, emphasizing the importance of predictive models in anticipating agricultural and natural resource challenges (Zhang et al., 2020).

Slide Four: Effects of El Niño on Weather and Food Production


The El Niño event of 2015 had sweeping effects on weather, food production, and water supply across the globe.
Drought in the Southern United States: In 2015, El Niño contributed to reduced precipitation and increased temperatures throughout the southern United States. Farmers faced agricultural crises, with crop yields significantly impacted by inadequate water supply (NOAA, 2016).
Human Health: The El Niño-induced drought exacerbated conditions for malnutrition and food insecurity in vulnerable populations. Reduced agricultural output strained local food systems, leading to increased prices and reliance on food aid.
One possible solution to mitigate these challenges is investing in water management and irrigation technologies. Implementing advanced irrigation techniques can help farmers optimize water usage during periods of reduced rainfall, thus preserving crop yields and maintaining food security (Fischer et al., 2019).

Slide Five: Conclusion


To effectively address the damaging effects of El Niño and La Niña, it is crucial to enhance preparedness and adaptive strategies.
Solution: Establishing regional climate action plans that incorporate predictive models and water conservation measures can significantly improve resilience against climatic shocks. These may include:
- Promoting sustainable agricultural practices to adapt to expected changes in precipitation.
- Developing comprehensive early warning systems to inform communities about impending weather patterns related to ENSO.
- Investing in infrastructure to better manage water resources during extreme weather events (Gbetibouo, 2018).
