[Asia Economy New York=Correspondent Baek Jong-min] The U.S. National Oceanic and Atmospheric Administration (NOAA) announced on the 10th (local time) that the La Ni?a phenomenon has occurred. As a result, this winter's weather is expected to be colder than usual, raising concerns about the impact on raw material prices such as crude oil and grains.

According to CNN, NOAA's Climate Prediction Center forecasted that La Ni?a will persist throughout the winter. NOAA had warned in July about the possibility of La Ni?a occurring this fall.

La Ni?a refers to a condition where the sea surface temperature near the equatorial Pacific is 0.5% lower than the average. It is the opposite of El Ni?o, which involves rising sea surface temperatures.

When La Ni?a occurs in winter, it causes abnormal cold waves, droughts, floods, landslides, and storms worldwide. Regionally, Southeast Asia experiences increased rainfall compared to normal. The southern United States sees abnormal heat, while the western region becomes drier. The northeastern U.S. is likely to face severe cold. Korea and Japan also have a high probability of experiencing a cold winter. The South American continent often suffers from drought.

In the U.S., there are immediate concerns about the possibility of another powerful hurricane occurring within the year. The New York Times expressed worries that the drought in the southwestern U.S., where severe wildfire damage is occurring due to La Ni?a, could worsen.

La Ni?a also has significant economic impacts. Weather anomalies reduce grain production, and heating demands often cause international oil prices to rise.
