Table.pdfPDF document27KDates of onset of the Northwest Mexico monsoon for each year, based on the daily precipitation index defined by Higgins et al. (1999). Note that 1951 and 1953 years never met the onset criteria.
Supplemental_Fig.1.epsPS document473KComparison of the terms of the thermodynamic equation at 500hPa for 15-day average before the onset (day -15 to day 1) and 15-day average after the onset (day 1 to day +15): (A,D) the temperature advection term (red represents warm advection and blue represents cold advection), (B,E) the vertical velocity term (blue represents rising motion and red represents subsidence), and (C,F) the diabatic heating term (red represents positive values and blue represents negative values). The contour interval is 0.43 K day-1 throughout.
Supplemental_Fig_2.epsPS document228KComparison of 18 strong and 18 weak advection monsoon years for the changes in precipitation for 15-day average after the onset (day 1 to day +15) and the 15-day average before the onset (day -15 to day 1) over northwest Mexico. The contour interval is 0.25 mm day-1.
Supplemental_Fig.3.epsPS document543KComparison of 18 strong and 18 weak precipitation years for southwest U.S. for the changes in the terms of the thermodynamic equation at 500hPa associated with the onset: (A, D) the temperature advection term (red represents warm advection and blue represents cold advection), (B, E) the vertical velocity term (blue represents rising motion and red represents subsidence), and (C, F) the diabatic heating term (red represents positive values and blue represents negative values). NCEP-NCAR reanalysis data is used to calculate the thermodynamic variables. The contour interval is 0.22 K day-1 throughout.
Supplemental_Fig4.epsPS document278KComparison of 18 strong and 18 weak precipitation years (shading) over SW U.S. and 200hPa winds (vectors) for 15-day average after the onset (day 1 to day +15) and the 15-day average before the onset (day -15 to day 1). The contour interval is 0.25 mm day-1 and a 10 m/s reference wind vector is given below the figure.
