| Abstract | Correlation between streamflows of the Gulf of California continental watershed (GCCW) and the 700 mb atmospheric flow patterns (AG700) has been poorly studied. Our goal was to study and understand the relationship between extreme conditions of AG700 and dry/wet periods of the zone of study with base on collected monthly streamflow data and inflow to dams volumes from 15 gage stations and 19 reservoirs. To accomplish our goal, average atmospheric flow patterns related to: wet (1) and dry (2) conditions; years with El Nino (3) and La Nina (4) conditions; and recurrent events of dry and wet periods (5) were estimated. Obtained results were compared with data of the Pacific Decadal Oscillation (PDO). The system of analysis involved data from: 1. Streamflows (between 1936 and 1999 period) 2. Inflow volumes to dams (1936 to 1999) 3. Monthly rainfall totals (1921 to 1999) 4. AG700 data (1948 to 1999) 5. PDO data (1900 to 1999) 6. Tree-ring series (1386 to 1998) Using the Empirical Orthogonal Function Analysis, data obtained allowed the clustering of observation points in three huge regions: Northern (rio Sonora basin); Central (from rio Papigochic basin to rio Fuerte basin); and southern (from rio Elota basin to rio San Pedro basin). As it is shown in the analysis at the 700 mb geopotential heights, in the delimited by us regions, seasonal atmospheric circulation patterns that well explain the genesis, dynamic, magnitude and relationship of the wet and dry periods are well displayed. We corroborated the correlation (teleconnection) between the hydrologic balance of the Northern, Central and Southern regions, PDO and the effect on this balance of El Nino and La Nina events. The results obtained provided useful information that should be considered in forecasting the seasonal and long-term hydrologic regime for the development of agriculture and industrial complex of the Northern, Central, and Southern regions. |
