Understanding Climate Influences: Key Factors and Terms Impacting Weather Patterns

This section explores various factors affecting climate, including prevailing winds and the Coriolis effect, which shape weather patterns across the globe. It highlights the significance of the doldrums, ocean currents, and phenomena like El Niño, demonstrating how these elements interact. Additionally, we examine the concepts of windward and leeward, along with the formation of rain shadows, illustrating how topography influences rainfall distribution. Understanding these factors is crucial for grasping climate dynamics and predicting weather changes.

  1. Chapter 3 Section 2 Factors Affecting Climate

  2. Key Terms • Prevailing Winds • Coriolis effect • Doldrums • Current • El Nino • Windward • Leeward • Rain shadow

  3. Prevailing Winds and Coriolis Effect • Prevailing Winds- wind in a region that blows in a fairly constant directional pattern. • Coriolis effect- An effect that causes the prevailing winds to blow diagonally rather than along strict north-south or east-west lines.

  4. Doldrums and Current • Doldrums- a frequently windless area near the Equator. • Current- cold or warm stream of seawater that flows in the oceans, generally in a circular pattern.

  5. El Nino • El Nino- a periodic reversal of the pattern of ocean currents and water temperatures in the mid-Pacific region.

  6. Windward and Leeward • Windward- facing toward the direction from which the wind is blowing. • Leeward- facing away from the direction from which the wind is blowing.

  7. Rain Shadow • Rain Shadow- dry area found on the leeward side of a mountain range.

  8. Arctic and Antarctic Circles
