Weather Pattern Diagram Instructions
1. Draw two diagrams: One of an El Niño weather pattern and the other of a La Niña
weather pattern.
2. Include:
- Title
- Drawing of United States, Texas, Mexico, top half of South America and
Australia
- Draw and label equator
- Label the Pacific ocean
- Draw a long rectangle at the bottom of the map that will represent the depths
of the ocean.
- Draw arrows (left or right) to show which direction trade winds are blowing
(colored pencil)
- Draw arrows to show direction surface ocean water is flowing (different
color than trade wind color)
- In Texas, indicate if the weather is dry or wet. (Label and color blue if wet
and brown in dry)
- In Australia, indicate if the weather is dry or wet. (Label and color blue if
wet and brown in dry)
- Indicate the general temperature the ocean would be at the surface and at the
bottom of the ocean during each weather event. (blue=cold, red=warm) - Indicate if the surface ocean temperature off the coast of South America is
Cold or Warm. (label)
- Draw a hurricane off the southeastern coast of Florida. Indicate, with arrows,
