El Nino: US Winter Temperatures Higher in mid continent Lower in south (Anomalies)
El Nino: US Winter Precipitation Higher in south and coastal regions (Anomalies)
Is there a difference?. Climate Vs. Weather Climate Long-term weather patterns of an area Weather Current state of the troposphere Short term variations.
El Nino El Nino is hot air over hot water, which causes warm winds El Nino means boy in Spanish and it causes wet period in Midwestern US.

Extratropical climate. Review of last lecture Mean state: The two basic regions of SST? Which region has stronger rainfall? What is the Walker circulation?
1 Surface Circulation Pathways Generally, warm currents move poleward and cool currents move equatorward.
