La Niña

La Niña is when the sea surface temperature becomes cooler than normal, a condition that prompts the easterly winds over the Pacific Ocean to produce more moisture in the air that eventually forms rain-inducing clouds. If a typhoon swirls this would further enhance the easterly winds and trigger stronger storm surges. Cold weather would follow once the northeast monsoon (Amihan) sweeps into the country from the plateus of Asia and the Himalayas, ring rain and cooler weather beginning November. The two (La Niña and Amihan) will merge. The northeast monsoon will add to the intensity of the strong easterly winds or trade winds, the weather specialist said.

Next three months we will experiencing wetter and colder weather when La Niña converges with the northeast monsoon. Residents living in the eastern seaboard off the Pacific Ocean will take the brunt of the above normal rainfall. This induced heavy rains and triggered floods, landslides and mudslides. Bislig will be directly hit by the above-normal rainfall. People should take precautionary steps to mitigate the adverse impact of this weather condition. PDI 9/27/07 www.nasa.gov
