  3. FT. HUACHUCA, AZ PROFILER 08-July-2002

  4. Douglas AZ dewpoint temperature 07-08 July 2002

  5. II. An analysis of mean wind roses during warm- dry months and cool-wet months in SE Arizona.

  6. WIND ROSE FOR DOUGLAS, AZ July-August (1973-2002) GMT

  7. DOUGLAS, AZ: CONTRASTING SURFACE WINDS (Jul-Aug) WARM/DRY COOL/WET 25.3ºC / 113mm 27.3ºC / 47mm

  8. July SLP anomalies (Cool/Wet - Warm/Dry)

  9. July 700mb Hgt. anomalies (Cool/Wet - Warm/Dry)

  10. III. Origin of surface moisture entering SE Arizona: A. West (Yuma Gulf Intrusions); South (Sonoran Valley Intrusions); Southeast (Rio Grande Intrusions) B. Surge frequency by month and surge type. C. Mean daily rainfall during the lifecycle of a surge event.

  11. SEEPAGE/SURGE TYPES

  12. SE ARIZONA: Long-Term Rainfall Stations

  13. High dew point days at Douglas can arise from any one or combination of the following: 1. Air mass moistening from a local rainfall event. 2. Mesoscale outflow boundaries arriving at the site. 3. Intensification of surface moisture advection under a strengthening SLP gradient. 4. Large scale synoptic forcing/moistening related to an approaching easterly wave, tropical cyclone or back door cold front. Question: How are these events related to local and synoptic scale forcing?

  14. IV. Relationships between surge events and: A. Hemispheric climate indices B. Regional climate indices.
