General weather patterns (hot/cold, wet/dry) are related closely to the position, strength and orientation of the jet stream (or jet streams). A jet stream at low levels is known as a low-level jet.

La Niña will likely influence the atmospheric circulation pattern this winter, with implications on the local conditions for the Great Lakes. What this can mean: • An active jet stream pattern across …

Conversely, during La Niña's, this dip in the jet stream shifts west of its normal position toward the Central Pacific. The position of this dip in the jet stream, called a trough, can have a huge …

The pocket of pressure falls causes low-level southerly winds to accelerate, which often paves the way for a low-level jet stream. Such a low-level jet stream rapidly transports moisture …

The northern polar jet stream is shifted northward across the United States, reducing the number of cold outbreaks across the central United States. During La Niña conditions, the jet streams …

During El Niño, a strong and amplified Pacific jet stream extending across the southern US in association with a polar jet stream shifted further north into Canada favors above normal …
