How MJO Teleconnections and ENSO Interferencce Impacts U.S. Precipitation
A composite analysis reveals how the Madden–Julian oscillation (MJO) impacts North American rainfall through perturbations in both the upper-tropospheric flow and regional low-level moisture availability. Upper-level divergence associated with the MJO tropical convection drives a quasi-stationary Rossby wave response to the midlatitudes.

Cloud Radiative Feedbacks and El Niño—Southern Oscillation
Cloud radiative feedbacks are disabled via “cloud-locking” in the Community Earth System Model, version 1.2 (CESM1.2), to result in a shift in El Niño–Southern Oscillation (ENSO) periodicity from 2–7 years to decadal time scales. We hypothesize that cloud radiative feedbacks may impact the periodicity in three ways, by: Read more “Cloud Radiative Feedbacks and El Niño—Southern Oscillation”
The South Pacific Meridional Mode as a Thermally Drive…
Abstract This study seeks to identify thermally driven sources of ENSO amplitude and uncertainty, as they are relatively unexplored compared to wind-driven sources. Read more “The South Pacific Meridional Mode as a Thermally Drive Source of ENSO Amplitude Modulation and Uncertainty”
