Introduction to La Niña and its Implications
The World Meteorological Organization (WMO) has issued a warning that the return of La Niña could start influencing global weather patterns from September. Despite this, the WMO anticipates that temperatures will remain above average in extensive regions worldwide.
Understanding La Niña
La Niña is a climate pattern characterized by cooler-than-average sea surface temperatures in the central and eastern equatorial Pacific Ocean. This phenomenon increases the likelihood of floods and droughts, which can negatively impact crop yields.
Current Climate Conditions and Predictions
Since March, climate conditions have remained neutral. However, the WMO suggests that these conditions could transition to La Niña in the coming months.
Recent Forecasts
According to the latest predictions, there is a 55% chance that the sea surface temperatures in the equatorial Pacific will cool to La Niña levels during the September-November period.
Economic and Humanitarian Impact
The WMO emphasizes that seasonal forecasts and their implications for weather can translate into significant economic savings for agriculture, energy, health, and transportation. Moreover, proper preparation for response actions can save thousands of lives.
Key Questions and Answers
- What is La Niña? La Niña is a climate pattern that results in cooler-than-average sea surface temperatures in the central and eastern equatorial Pacific Ocean, increasing the probability of floods and droughts.
