La Niña tends to cause flooding in Australia, Asia, and Indonesia and drought in North and South America. La Niña events, while not as well known as El Niño, can have equally drastic worldwide climate effects. The low ocean temperatures of La Niña generally last 9 to 12 months, but can persist for up to 2 years. Both El Niño and La Niña are part of what is known as the El Niño–Southern Oscillation, or ENSO. Although these events occur irregularly and cannot be predicted, they are occurring more frequently in recent years, which some scientists suggest may be attributed to global warming.

2. What happened when the hair dryer stopped blowing across the water? What ocean condition does this represent? 3. How are ocean temperatures related to weather? 4.

In intermediate conditions, water exists as a liquid. At high temperatures and low pressures, water is a vapor. Because of this, warm air contains more water vapor than cooler air. Therefore, as warm air comes in contact with cool temperatures or high pressure, the water vapor within it condenses into its liquid form.
