The aim of this presentation is to examine precipitation, temperature, and wind information derived from the European Centre for Medium-Range Weather Forecasts Interim Reanalysis (ERA-I) to compare MJO events during QBOE/SMIN and QBOW/SMAX conditions from a climatology and composite perspective. The ERA-I dataset is available at 1x1 degree latitude-longitude grid spacing at 6-hour intervals for the period 1979-present. The MJO events for QBOE/SMIN and QBOW/SMAX conditions are stratified by MJO phase as determined from the outgoing longwave radiation-based MJO index (OMI). Preliminary results show that MJO events that occur during QBOE/SMIN conditions are characterized by increased precipitation rates compared to events during QBOW/SMAX conditions. Additionally, MJO events in phase 5 of the OMI show increased precipitation rates in the coastal northwest United States and British Columbia in association with atmospheric rivers in QBOE/SMIN conditions compared to QBOW/SMAX conditions. This result suggests that the MJO influence on midlatitude flow and atmospheric river events may be modulated by the QBO and solar cycle. Composite analysis of the lower stratospheric static stability and wind field stratified by QBO regime and solar cycle will also be presented. It is suggested that these results are potentially useful to for weather and climate applications regarding the effects of solar variability on tropical deep convection and seasonal-to-subseasonal variability.
