Possibility of La Niña
On the other hand, in the eastern Pacific Ocean near the equator off the coast of South America and Peru, there is a high possibility that the "La Niña phenomenon", in which the sea surface temperature is lower than normal, is occurring. When this phenomenon occurs in Japan, the temperature tends to be higher in the beginning of autumn and lower in winter than in normal years, so it is necessary to pay attention to future weather information.
