La-Nina

This phenomenon generally follows an El Nino. La Nina is sometimes referred to as El Viejo, The Little Girl, anti-El Nino, or simply ‘a cold event’ or ‘a cold episode’. La Nina (pronounced Lah Nee-Nyah) is the cooling of water in the Pacific Ocean.
It is characterized by unusually cold ocean temperatures in the Equatorial Pacific, compared to El Nino, which is characterized by unusually warm ocean temperatures in the Equatorial Pacific. Typically, La Nina occurs roughly half as often as El Nino.
The impacts of La Nina impact on the global climate and ocean temperature tend to be opposite those of El Nino. In the US, winter temperatures are warmer than normal in the south-east and cooler than normal in the north-west during a La Nina year. temperatures are warmer than normal in the Southeast and cooler than normal in the Northwest.
Snow and rain is experienced on the west-coast and unusually cold weather in Alaska. During this period there are higher than normal number of hurricanes in the Atlantic.
El Nino and La Nina are the most powerful phenomenon on the earth and alter the climate across more than half the planet.
