What factors influence weather patterns around the world?.

Weather patterns are influenced by multiple factors including:

1. Atmospheric Conditions: Variations in pressure systems, humidity, and temperature drive local weather changes. High and low-pressure areas can lead to different weather phenomena.

2. Geographical Features: Mountains, valleys, and bodies of water can alter climate and weather patterns. For example, mountain ranges can block or enhance precipitation.

3. Ocean Currents: Warm and cold ocean currents affect regional climates. The Gulf Stream, for instance, warms the eastern U.S. and western Europe.

4. Solar Radiation: The amount of solar energy received at different latitudes influences temperature and weather variability.

5. Human Activities: Urbanization and deforestation can modify local climates, creating 'urban heat islands' that change precipitation patterns.

Key Facts

• The Earth’s atmosphere is made up of layers, each affecting weather.
• Ocean currents can travel thousands of miles and impact climates around the globe.
• Approximately 70% of Earth’s surface is covered by water, crucial for weather dynamics.

Examples or Use Cases

• El Niño and La Niña events showcase how oceanic conditions can drastically alter global weather.

FAQs

1. What is the difference between weather and climate?
