Weather Tidbits: La Niña
This Weather Tidbits dives into La Niña. La Niña is when the waters of the eastern & central Tropical Pacific Ocean are cooler than normal. This creates for dry & mild conditions for the southern half of the United States & wet conditions for the Pacific Northwest. A high pressure sets up south of Alaska dropping the polar jet over the Western United States. The dip of the polar jet leads to variability over the Northeast with quick bursts of cold air but also occasional interactions of milder air from the South.
