Drier weather to the Pacific Northwest. Climate during northern summer are analyzed separately. Composite analyses reveal that a continental-scale anomalous high dominates over most of North America during La Niña events and leads to hot and dry summers over the central United States.

However it can have effects on weather all over the world. There is also a notable South America crop weather impact when La Nina is in effect. La Niña and its warm counterpart El Niño can affect weather patterns thousands of miles away in the United States and around the world particularly in winter.

Southern Brazil and central Argentina have a strongly identified relationship to. Global climate La Niña impacts tend to be opposite those of El Niño impacts. America because La Niña has an impact on our weather patterns most predominantly in winter.

For the United States the most significant impact is a shift in the path of the mid-latitude jet streams. Although each La Niña is different there are some general patterns that are predictable.

Generally speaking El Niño brings. La Niña features unusually cold weather in the Northwest and to a lesser extent northern California the northern Intermountain West and the north-central states. Climate Prediction Center Deputy Director Mike Halpert said in a press release that La Nina can contribute to an increase in Atlantic hurricane activity by weakening winds over the Caribbean.

The largest negative impacts associated with La Niña are increases in heating costs snow removal and difficulties in transportation.
