Winter Outlook for West Central and Southwest Florida I also have noted that the tropical atmosphere has been more persistently La Nina-like than the Nino region sea surface temperatures in recent months. Drier conditions also develop in the southeastern United States as La Nina produces a weaker subtropical jet stream and less moisture over the southern United States.

To analyze the effect of different sea surface temperature patterns on early-winter precipitation in the Southwest during La Nia, I first defined two groups: the wettest 20% and driest 20% of simulations.
