Droughts and Moisture Transport( SETH) 

Summary:

Previous works have pointed out the increasing number and intensification of natural hazards related to extremes in precipitation and drought conditions, and many of them alert about the role of climate changes of antropogenic origin. The investigation of the anomalous moisture transport before, during, and after the ocurrence of the most important drought episodes observed worldwide in the last thirty years is the purpose of the present project. Concerning trajectories of air masses, sources and sinks of humidity evolved, the lagrangian perspective can offer more detailed information than the eulerian one in studies of transport of moisture, what justifies its application in this study. The lagrangian approach proposed here uses the model FLEXPART integrated with the ERA-Interim data set and it has been successfully applied in previous studies concerning the climatological characterization of the sources and sinks of moisture in several regions around the world. The drought episodes are identified and characterized through the SPEI index. For each one of the drought events selected, the methodology proposes to investigate the role of the area affected as an receptor/source of moisture. Changes in land and oceanic evaporation are also analyzed in order to identify for which drought cases the changes in the oceanic or continental sources were more significant. A better understanding not only of the transport of humidity, but also of the relationship between sources/sinks of moisture and of possible impacts generated by variations in the sources is crucial for a more accurate weather forecast, helping to minimize the consequences of the natural hazards

General objectives:

The purpose of this project was to investigate the anomalous moisture transport during the ocurrence of the most important drought episodes worldwide in the last 30 years through a lagrangian methodology.

Specific objectives are:

  1.  Identification and characterization of the most important drought episodes during the period 1980-2015 through the SPEI index.
  2. For each episode selected, the objectives 2, 3, 4, and 5 are developed:
  3. A climatological identification of the major sources and sinks of moisture of the regions where the drought happened;
  4. Analysis of the anomalous moisture sources and sinks during the drought episodes;
  5. Analysis of the anomalies of evaporation;
  6. Analysis of the relative importance of the oceanic and continental sources.
