Drought frequency analysis and prediction in Sonora, Mexico

Document Type

Conference Proceeding

Publication Date



Sonora is located in northwestern Mexico, an arid region which has suffered from drought for the last nine years. Using available precipitation data, we conduct a drought frequency analysis and investigate teleconnections with recurrent atmospheric anomalies such as El Niño/Southern Oscillation and the Pacific Decadal Oscillation. Upon completion of these analyses, we will investigate how drought intensity-duration-frequency estimates and seasonal drought forecasts can be useful to farmers and other water managers in Sonora.
