- This study examined the relative importance of wind-induced surface flux feedbacks to MJO convective destabilization using two RAMA buoys along the equator at 80.5°E and 90°E.
- Fig. 2 shows that intraseasonal latent heat flux (LHFLX) anomalies are roughly 5-7% of TRMM precipitation anomalies at the buoys. Since moist static energy is exported by vertical motions at roughly 10-20% of precipitation (Yu et al. 1998, Sobel et al. 2014), we conclude that LHFLX are an important, though not sufficient, source of moisture for MJO destabilization.
- Fig. 6 shows that wind variability is the dominant contributor to LHFLX anomalies across MJO events, which highlights the importance of wind-induced fluxes to MJO convection.
