Final answer:
The Hadley circulation is characterized by wet conditions near the equator and dry conditions near 30 degrees latitude. El Niño and La Niña are not characteristics of the Hadley circulation but part of ENSO, and the ozone hole is unrelated.
Therefore the correct options are C. Dry, arid conditions near 30 degrees North and South latitude and D. Wet, rainy conditions near the equator
Step-by-step explanation:
The characteristics of the atmosphere's Hadley circulation include dry, arid conditions near 30 degrees North and South latitude and wet, rainy conditions near the equator. These conditions are a result of air rising at the equator due to heating by the sun, leading to precipitation, and then descending around 30 degrees latitude, which creates drier areas.
While events like El Niño and La Niña are associated with changes in weather patterns around the world and can interact with the Hadley circulation, they are not its characteristics and are part of the broader El Niño Southern Oscillation (ENSO). In contrast, the stratospheric ozone hole is not directly related to the Hadley circulation, but rather to chemical reactions in the atmosphere primarily involving chlorofluorocarbons (CFCs).
