  8. Model of a Gulf Surge Transports moisture up the Gulf of California, up the Colorado River valley, and into the American Southwest.

  9. Model of a Gulf Surge A Thermal Low exists over the deserts of Arizona and southern California.

  10. Model of a Gulf Surge To get a Gulf Surge, you need to create an area of High pressure near the southern tip of Baja California. H

  11. Model of a Gulf Surge Low level easterly waves slide across Central America, bringing convection.

  12. Model of a Gulf Surge • When the convection is across the mouth of the Gulf of California, a region of relatively high pressure is created DUE TO COOLING. • Evaporation of raindrops • Reduced solar heating H

  13. Model of a Gulf Surge At Yuma, Arizona: Winds shift out of the south-southeast. Temperatures FALL. Dewpoints RISE. H

  14. Diurnal Cycle High altitudes have a peak of convection in mid afternoon. Low altitudes have a peak at night.
